Product information "EXPLORE SCIENTIFIC APO 165 mm FPL-53 CF 3,0"FT"
This excellent telescope is the currently largest representative of a new line of apochromatic refractors by EXPLORE SCIENTIFIC. The completely new designed optics contains the special glas FPL-53, and delivers stunning sharpness and contrast without any trace of color abberation. For a apochromatic refractor of this size the focal ratio is relatively fast - the f/7 optics is thus also very suitable for astrophotography. For this reason we added one of the world’s top focusers - the high precision and the famed rigidity of the 3" Feathertouch focuser make focusing an easy task - and unwanted movements of the sensor during exposure do not happen. The result of this combination of outstanding optics, top level mechanics and the relatively low weight is a extremely versatile telescope that wil not only give images of the moon and planets that are perfect. It will also exceed the expectations of even the most demanding amateur astronomers in the field of astrophotography.

EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector
The EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector, reduces a compatible telescope's focal length by a factor of 0.7x (for around f/8) and 0.8x (for around f/10) respectively. The reducer/corrector not only reduces the focal length but also flattens the field. Although originally developed for the Explore Scientific ED-APOs 127mm and 152mm, the reducer can be used with many systems - for example with the Explore Scientific ED-APOs 102mm and 165mm (please note, this will not work on the Explore Scientific 80mm ED Apo refractors though). With certain telescope focal lengths, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. This unit comes with 3" barrel adaptor for direct focuser thread M54x0.75 (the standard focuser thread of the Explore Scientific Essential series of ED Apos) and T2 camera adaptor. This reducer/corrector features a free aperture of 65mm, so that it can be used even with cameras that have a large sensor - if the telescope allows for this. Note: As previously mentioned, this Reducer/corrector comes with a screw on ring, which fits the standard focuser thread of the Explore Scientific Essential series of ED Apos. For telescopes which are equipped with the 2.5" HEX Focuser, the optional screw-on adapter part no: 0510366 is needed. Other telescopes, not in the Explore Scientific range, with standard 2" push-fit focusers will need the Explore Scientific 2" Adaptor for 3" Corrector - part no: 0510364 to get this reducer correctly fitted. SPECIFICATIONS Reduces the focal length by 0.7x at f/8 Flattens the field for astrophotography Developed for ED127 und ED152 APO telescopes Also fits Explore Scientific ED102 and ED165 telescopes - and others Free aperture: 65mm Inner thread for telescope adaption: M76x0.75mm Outer thread for camera adaption: M72x0.75mm 3" focuser barrel adaptor included Adaptor for Explore Scientific focuser M54x0.75mm included T2 camera adaptor M42x0.75mm included Diameter: 78.5mm; length: 100mm Length without adaptors: 52mm Weight without adaptors: 530g What's Included Reducer/Flattener 3" focuser barrel adaptor Adaptor for Focuser M54x0.75mm T2 camera adaptor M42x0.75mm Dust caps

EXPLORE SCIENTIFIC 82° Ar Eyepiece 14mm (1,25")
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC 1.25" CLS Nebula Filter
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer.  The EXPLORE SCIENTIFIC CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x CLS filter

EXPLORE SCIENTIFIC 1.25" H-Beta Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The Explore Scientific H-beta filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen. The Explore Scientific H-beta nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the horsehead nebula is almost not visible with a 300mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters.

EXPLORE SCIENTIFIC 2" H-Beta Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The Explore Scientific H-beta filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen. The Explore Scientific H-beta nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the horsehead nebula is almost not visible with a 300mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

EXPLORE SCIENTIFIC 2" O-III Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, the so called emission lines. Those emission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the veil nebula NGC 6992 is almost not visible with a 200mm telescope. By using this filter you can see the nebula and its structures without problems.

EXPLORE SCIENTIFIC 2" UHC Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of the celestial object, it is possible to dramatically increase the contrast by blocking annoying artificial light. The EXPLORE SCIENTIFIC UHC filter "zeros in" on the wavelengths of so-called emission nebulae. Those objects glow in special colours - their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colour wavelengths (and thereby nearly all of artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely invisible from, without filters. In suburban skies, for example the Owl-nebula M97, the Veil-nebula NGC 6992 or even the bright Dumbell-nebula M27 are not clearly visible. Using this filter allows you to see nebulae and their structures in much finer detail. A must for every visual observer.

EXPLORE SCIENTIFIC 2" Variable Polarizing Filter
Universally usable variable polarizing filter with a  2" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 2.0" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing2.0" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

EXPLORE SCIENTIFIC Dark-Sky Filter 77mm Slim
Universal Dark-Sky Filter with 77mm thread for photo lens. Contrast enhancing filter for Aurora- and Deep-Sky imaging. Especially during Aurora imaging the most important wavelength of 550nm (green) and 630nm (red) this filter let pass by 90%. In comparrision to CLS filters, the Explore Scientific Dark-Sky Filter is blocking also the yellow Sodium (Na) wave at 590nm which elliminates Sodium-lamp street illumination from your picture. This is very useful because the yellow light is always a partially mix of green and red light. Removing the yellow wave-length with any image processing software will always damping also the green and red coloring. For Aurory imaging this is of course not wanted. At these days of increasing light pollution, the Explore Scientific Dark-Sky Filter is absolutely recommended in order to take pictures also from urban conditions.

BRESSER Spica-II 130/1000 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Embark on a voyage of discovery through our solar system and beyond using the BRESSER Spica-II reflector telescope. You can start straight away with your new hobby, because this complete astronomy set already comes with everything you need for exciting observations: an astronomical reflector telescope with 130 mm aperture and 1000 mm focal length, an equatorial mount, a tripod and extensive accessories. Perfect for the astro-novice: the system is very easy to use. So look forward to fascinating sights especially of the Moon, the planets and the Sun. Perfect combination of mirror and lens – the telescope Using the Spica-II you’ll start your celestial exploration tour with a classic reflecting telescope of the "Newton" type with an additional lens inside the focuser. This combination of mirror and lens is called "catadioptric". It’s immediately noticeable with this type of telescope that you do not look in at the back, but at the front and laterally. What is the advantage? Even if the telescope is pointed vertically into the sky, you can observe the beauties of the night sky in a comfortable posture. In addition, catadioptric telescopes impress with their transportability, because despite the long focal length, the tube is comparatively short. With its 130 mm aperture, the Spica-II already collects a lot of light from celestial objects. In addition, 130 mm aperture and 1000 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 7.7 (F/7.7). This means you can enjoy an image with good contrast even at high magnifications. Thus, the telescope is well suited for observing the planets and details on the Moon. Even some deep sky objects are worth looking at through this entry-level telescope: admire open star clusters and globular clusters as well as bright so-called planetary nebulae such as the Ring Nebula M57 in the constellation Lyra. And how big will the nocturnal highlights appear? The 130 mm aperture achieves a resolution that allows magnifications of up to about 260x with sharp images. Technically, even more is possible – theoretically up to 750x with the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. In addition, as is so often the case in astronomy, you are also dependent on the prevailing conditions. For example, the air turbulence in the atmosphere (seeing conditions) always plays a role in your magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Spica-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. A good foundation for your astro-start – mount and tripod If you want to look up at the sky, you need a solid base on the ground. That's why you will find a robust height-adjustable aluminium tripod and an equatorial mount in your telescope set. The special advantage of this type of mount: unlike an azimuthal model, the movement of the celestial bodies is compensated for only on one axis instead of two. For this purpose, one axis of the equatorial mount is aligned parallel to the Earth's axis in the course of the so-called "alignment". This is easily done by pointing it approximately at Polaris. Perfect for convenient adjustment and tracking of the entry-level telescope: the axes can be moved precisely via the two flexible shafts with fine adjustment. And if you simply place smartphone adapter, eyepieces etc. on the convenient storage plate between the tripod legs, you will have the equipment you need quickly at hand.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything for the astro-beginner – the accessoriesFor your start into the wonderful world of astronomy, the Spica-II beginner's telescope comes with lots of accessories. The LED viewfinder, for example, is great for orientation in the night sky. You simply install the direction finder parallel to the actual telescope. It projects a red dot onto a small ground-glass screen that appears to float in front of the sky when you look through it. In this way, it shows you where the telescope is pointing. A great help for the exact alignment of the telescope and the easy location of celestial objects before you gaze at them with higher magnifications. You determine how detailed you observe your discoveries by using one of the two eyepieces, each of which provides a different magnification. They are fitted with standard 1.25-inch (31.7 mm) diameter sockets which allow them to be easily inserted into the eyepiece focuser of the entry-level telescope. Would you like to look even closer? Then grab the 3x barlow lens, which triples the magnification of the eyepieces in no time. Explore the astronomical highlight of the daytime sky: With the safe solar filter you can examine sunspots as well as granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! There is also a suitable accessory for your first steps in astrophotography: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. First snapshots of the Moon or Sun made easy!

BRESSER Pollux-II 150/1400 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Explore the beauties of the night sky with this complete telescope set. Everything is included so that you can get started immediately with the fascinating hobby of astronomy: the astronomical reflector telescope with 150 mm aperture and 1,400 mm focal length, the equatorial mount, the tripod and extensive accessories for exciting observations. Especially important for beginners: the system is very easy to use. Particularly the Moon, the planets and the Sun appear impressive through the Pollux-II. Powerful performance for your first celestial observations – the telescope Take your first steps in astronomy with this classic reflector telescope of the "Newton" type. Because it is equipped with an additional lens inside the focuser, it belongs to the group of the so-called "catadioptric" optics. One advantage of this combination of lens and mirror: despite the large focal length, the telescope tube is relatively short and therefore easily transportable. In addition, you can look forward to a comfortable observation position at all times. This is because with telescopes of this design you do not look in at the back of the telescope, but at the front and laterally. So you don't have to bend down, even if the reflector telescope is pointed vertically upwards at the sky. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 1,400 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 9.3 (F/9.3). This allows you to enjoy viewing your favourite objects at high magnifications with good contrast. Admire especially the planets or details on the Moon through the entry-level telescope. But also some deep sky objects are very nice to observe: open star clusters, globular clusters and bright planetary nebulae such as the Ring Nebula M57 in the constellation Lyra can be seen beautifully through this astronomical telescope. But how close can you get to the celestial eye-catchers? The 150 mm aperture achieves a resolving power that allows magnifications of up to 300x with sharp images. The technical possibilities go far beyond this – theoretically up to 1,050x using the included accessories. However, as the magnification increases, the sharpness of the image can slowly decrease. In addition, high magnification also requires the right environmental conditions. For no matter through which telescope you look, the air turbulence in the atmosphere (seeing conditions) always influences your observation and magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Solid base for gazing skywards – mount and tripod Have you found the perfect location for your journey of discovery into the night sky? Then simply mount your astronomical telescope with the equatorial mount on the height-adjustable aluminium tripod. The special feature of this type of mount: after the so-called "alignment", the positioning of an axis parallel to the Earth's axis, the movement of the celestial bodies only has to be compensated for on this one axis. To do this, you simply point the axis approximately at Polaris. This is a huge advantage over the azimuthal mount, where both axes are moved simultaneously. In addition, the two flexible shafts with fine adjustment make adjusting and tracking the telescope very precise and comfortable. And to ensure that accessories are always at hand, they can be stored on the handy shelf between the tripod legs.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything you need, night and day – the accessories The astronomical telescope comes with a wide range of equipment so that you can start admiring the Moon, planets or the Sun straight away. At night, the LED viewfinder helps you keep an overview of the sky. Once installed parallel on the tube and correctly aligned, the small red dot shows you where the telescope is pointing when you look through it. This way, you can align the optics precisely and find celestial bodies more quickly before you then take a closer look with the high magnification. Varying views of the universe: the two eyepieces allow you to marvel at your observation objects in different magnifications. They are simply inserted into the telescope's focuser using their sockets with a standardised 1.25 inch (31.7 mm) diameter. You want to see even more details? Then go for the 3x barlow lens, which triples the magnification of the eyepieces. If you would like to make astronomical discoveries even during the day, use the solar filter to observe the star of our own solar system. It allows you to easily and safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Capture special highlights easily – with the smartphone adapter, you use your smartphone as a camera for your telescope. This way you can quickly take your first photos of the Moon or the Sun, for example, and get started in astrophotography.

BRESSER Sirius 70/900 AZ Refractor Telescope with Smartphone Camera Adapter
Set off on your personal journey to the stars with the BRESSER Sirius 70/900 AZ lens telescope. The complete astronomy set already includes everything you need to start observing the sky: the astronomical lens telescope with 70 mm aperture and 900 mm focal length, the azimuthal mount, the tripod and a wide range of accessories for fascinating discoveries. At the same time, it is very easy to operate - ideal to amaze even children with a view of the night sky. Simply a stargazing classic - the telescope With this lens telescope - a so-called Fraunhofer achromatic refractor - even total astro-beginners and children can easily explore the secrets of our night sky. Because this classic design impresses with its special user-friendliness and easy handling. To ensure that you enjoy good imaging properties when looking at the Moon, Sun, planets and star clusters, the entry-level telescope has been equipped with modern, precisely coated optics. The 70 mm aperture collects a total of 100 times more light than the human eye. And it is also convincing compared to a comparable 60 mm telescope: the light gathering capacity is 36 % higher and the resolving power is also better. Thus, with the 70 mm lens telescope, significantly more details are visible at the same magnification, e.g. on Saturn's rings or the two main cloud bands of Jupiter. But how big do the celestial objects appear then? The resolution of the 70 mm lens lets you enjoy really sharp images at magnifications up to about 140x. For comparison: with a 60 mm aperture, this is only possible up to 120x. Technically, of course, the starter telescope can do even more - theoretically up to 675x with the included accessories. However, with increasing magnification, the image can slowly become more and more blurred. And how big you can really see the planets, star clusters and co. depends not only on the telescope. Another important factor: the air turbulence in the atmosphere (seeing conditions). A sharp image with good contrast - this is what the starter telescope achieves with its large focal ratio of about 1 to 12.9 (F/12.9), which is calculated from the ratio of the 70 mm aperture to the 900 mm focal length. And you will see: Due to the long focal length, especially the Sun, Moon, planets, open star clusters and globular clusters become absolute eye-catchers. Solid base for your stargazing hours - mount and tripod Found the ideal location for your nocturnal explorations? Then attach the telescope tube to the height-adjustable aluminium tripod with azimuthal mount. And this azimuthal mount is particularly compelling due to one quality: operation is really child's play. Simply swing the telescope by hand to the left or right, up or down, as with a common photo tripod. This way you can quickly move your gaze from one celestial highlight to the next. And where are the accessories? Simply place them on the storage plate between the tripod legs. This way, eyepieces, solar filter and co. stay always within reach. All the trimmings - the accessories The beginner’s telescope comes with everything you need for a quick start in stargazing. When searching for celestial bodies worth seeing, take your first look through the included LED viewfinder. Because the direction finder helps you to align the telescope precisely and find astronomical objects. It works like this: The LED finder is mounted in parallel on the telescope tube. It projects a red dot onto a small ground-glass screen that appears to float in front of the sky when you look through it. And that is exactly where the aperture of your telescope points. This way, you can always keep an overview of the night sky - before focusing your attention on the details through the magnification of the telescope. And you decide how high this magnification is by choosing the eyepiece. You will be amazed: the two eyepieces included in the set (4 mm, 20 mm) allow you to admire completely different images of the same object. If you one day want a change of perspective, you can expand your astronomy set with a large selection of eyepieces. For this purpose, the socket diameter is 1.25 inches (31.7 mm), which corresponds to an international, manufacturer-independent standard. You like what you see, but would love more detail? Then simply insert the 3x Barlow lens between the telescope and the eyepiece. And you have tripled the magnification of the eyepiece! Observation comfort and a pleasant view - this is what the 90-degree star diagonal mirror is made for. Even if your starter telescope is pointed vertically into the sky, you don't need to lie down underneath it to see anything. Instead, simply look in comfortably from the side and enjoy the view. But it's not only at night that we should look skywards. For only during the day you can see a very special star: our Sun. So put the solar filter in front of the lens and safely look at sunspots and granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! Would you like to share your discoveries with friends and family? Then take your first steps in astrophotography right away - and those are done in no time with the smartphone camera adapter for your beginner's telescope. The Moon, Sun, planets, open star clusters and globular clusters always make a good picture. Discover what our night sky has to offer with the BRESSER Sirius 70/900 AZ refracting telescope.

Explore hidden worlds through your own eyes – with the BRESSER Pollux-I telescope starter set for budding amateur astronomers, you can go on your own journey of discovery in outer space. Everything you need is already included: the astronomical reflector telescope with 150 mm aperture and 750 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Perfect for getting started quickly: the system is very easy to use. In addition, the entry-level telescope impresses with its versatility: you can observe the Moon and planets as well as star clusters, gas nebulae and even galaxies through the high-quality optics. Due to the parabolic primary mirror the image delights with impressive sharpness and high contrast. In addition, the 2-inch focuser allows for the use of high-quality eyepieces. Perfect conditions for fascinating sights of the night sky! Time-proven optics for your first astro-steps – the telescope By choosing the Pollux-I, you’ll start your journey to the stars with a classic Newtonian reflector telescope. Beginners are often surprised by the fact that with telescopes of this type you don't look in at the back of the tube, but at the front and laterally. This gives you the advantage of always being able to look into the telescope in a comfortable posture, even when it's pointed vertically upwards at the sky. In addition, these reflector telescopes offer optics that are absolutely free of chromatic aberrations and thus provide good imaging properties. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 750 mm focal length result in a short focal ratio (ratio of aperture to focal length) of 1 to 5 (F/5). On the one hand, this makes the telescope fast and provide a bright image. On the other hand, high magnifications can be achieved. This combination makes the entry-level telescope so versatile. In addition, the Pollux-I is equipped with a parabolic primary mirror. The remarkable effect of this special mirror shape: you enjoy excellent imaging properties at all magnification levels. So you can look forward to the complete range of celestial highlights. At low to medium magnification, you can admire deep-sky objects such as open star clusters, globular clusters, gas nebulae and even galaxies such as the pair of galaxies M65 and M66 in the constellation Leo. And at high magnifications, observing the planets or details on the Moon is an absolute pleasure. You can get really close to your favourite objects: The aperture of 150 mm achieves a resolving power that allows magnifications of up to about 300x with sharp images. Technically, even higher magnifications are possible, theoretically up to 562.5x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition, the prevailing conditions always make a difference: How highly you can magnify always depends not only on the power of the telescope but also on the air turbulence in the atmosphere (seeing conditions). The telescope also impresses with its flexibility in terms of eyepiece compatibility: it comes with a 2-inch focuser (focuser extension) and an adapter from 2 inch to 1.25 inch. This enables you to use eyepieces with 1.25-inch sockets (about 31.7 mm) as well as eyepieces with the larger 2-inch sockets (about 50.8 mm) with large fields of view. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-I reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Perfect foundation for fascinating discoveries – mount and tripod Your beginner's telescope is securely held by the height-adjustable aluminium tripod with equatorial mount. The special feature of this mount, also known as a parallactic mount: in contrast to azimuthal models, the movement of the celestial bodies is only compensated for on one axis instead of two. For this purpose, you simply align one axis parallel to the Earth's axis by pointing it approximately at Polaris. For precise and comfortable alignment and tracking of the entry-level telescope, the Pollux-I comes equipped with two flexible shafts with fine adjustment. And to ensure that the interchangeable eyepieces, barlow lens etc. always remain within reach, they can be stored on the tray between the tripod legs.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory.

Vixen AXD2 with VMC 260 Maksutov-Cassegrain Telescope
AXD2 GoTo mount with VMC260L telescope set The AXD2 mount comes with the new STARBOOK TEN controller and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars. This telescope set has everything that you need for hobby astronomy. The set includes a telescope, a mount with automatic tracking and a stable tripod. Featuring the STARBOOK TEN controller, the telescope locates celestial objects automatically so that you don’t need to search for them manually. Even if you’re not an expert, you can still give your friends an exciting tour through the night sky! The AXD 2 mount in detail: Robust construction and lightweight housing with 30 kg load capacity (photographic) The RA and DEC axes are made using the A7075 superalloy, one the strongest aluminium alloys. The stability of the A7075 superalloy is stronger than titanium, which is known for its strength as a lightweight material. Its thickness is 38% less than titanium. Using the A7075 superalloy for the axes ensures that the AXD mount is both lightweight and stable. 21 bearings The rotating parts of the AXD mount have a total of 21 bearings. These ensure uniform motion in order to swivel the telescope and track objects. Stepper motors Vixen uses precise stepper motors for the mount in order to ensure optimal performance. The motors are controlled via a micro-step motion control system, which eliminates the disadvantage of stepper motors with large steps. The system generates 400 impulses per second at a high speed. This results in very quiet scanning with no vibrations. The stepper motors on the AXD mount have sufficient torques. This is most significant when working at high magnifications and photographing with a CCD camera with small pixel sizes. Worm gears The sizes of the worm gears were increased in the latest Atlux version. The AXD mount has 270 teeth in the RA axis and 216 teeth in the DC axis. Both axes are 50 mm in diameter. This ensures that the mount operates with precision and stability. Low backlash The Vixen micro-step motion control system ensures that the stepper motors run uniformly at low and high speeds. This eliminates the need for reduction gears in the motor and therefore reduces the backlash in the gears. Elegant design The flat sides of the mount were designed based on previous generations of the New Atlux range. The white and silver housing provides a modern and elegant exterior with high functionality. The AXD is the flagship model in the Vixen mount range. Original motor layout The solid RA and DEC motor units are arranged in the lower part of the mount. This means that they automatically act as a counterweight. As a result, you require far fewer weights on the counterweight bar. On small devices, no counterweight is required. The counterweight bar can be slid fully into the housing. Polar finder scope The AXD mount is equipped with a 6x20 polar finder as standard. The polar finder features an integrated scale, which provides a quick and easy way to polar align the telescope in the northern hemisphere. For observations in southern latitudes, the polar finder features an image of the Octans constellation, which can be aligned with the night sky. VPEC periodic error correction Periodic errors on mounts are usually measured and corrected by the user. Unlike the old StarBook controller, the STAR BOOK TEN controller saves these errors permanently. The periodic error of the mount is measured in the factory and corrected before delivery. This is known as VPEC and functions automatically as soon as you use the mount. It delivers an accuracy of +/- 2.8 arc seconds. You can increase the tracking accuracy further by saving your own recorded periodic errors. The VMC 260 in detail The optics of the VMC260L are significantly better than the traditional Schmidt-Cassegrain telescope. Despite its high 3000 mm focal length, it is just 650 mm long. Featuring a large 260 mm aperture, the telescope collects large amounts of light for serious professional observations and photography of the planets and countless deep-sky objects. Thanks to the dielectric mirrors, the VMV260L guarantees razor-sharp images and maximum brightness. The open lens barrels cool the telescope quicker than conventional closed Cassegrain systems. The telescope can be used with an optional 0.62x focal reducer to reduce the aperture ratio to 1:7.1. This shortens the exposure times and allows you to photograph large objects. The telescope comes with a standard dovetail bar and a carry handle that doubles up as a camera holder for night sky photography.

EXPLORE SCIENTIFIC Ultra Light 20'' Dobson 500mm f/3.6 GENERATION II
Ultra Light Dobsonian 500mm GENERATION II - telescope mechanics handcrafted in HUNGARY and GERMANY No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto held together by gravity and driven by yoghurt power and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector (part No. 0510330) . The ideal workhorse for the deep-sky enthusiast. A telescope with 500mm aperture gathers more than 5100-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details and some color. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience. The fast 20’’ f3.6 main mirror as well as the large 120mm secondary mirror are made of high quality quartz material, so the cooling time is reduced to a minimum and the Dobson is quickly ready for use. Every main mirror is delivered with an individual optical test certificate, which guarantees the highest capacity. A laser engraved center mark of the main mirror allows easy adjustment. The optical surface has a high-quality aluminum silvering with 94% reflectivity and an extremely resistant quartz protection layer. The mirror overcomes frequently occurring dew fogging and cleanups without any damages and guarantees a long service life. A complete redesign of this Dobson was necessary to ensure the significantly increased requirements to stiffness and load bearing capacity of the optical components. All connections of the tube structure were made in the TIG welding process and no rivets and screws were used. This has made it possible for us to produce this 20’’ light weight Dobson so unbelievably stiff in spite of the low weight - a noticeably good quality which is searching for its match. The production of almost all mechanical components is carried out by our partners in Hungary and the final assembly of the optics and subsequent quality control takes place in Rhede, Germany. The equipment details of the smaller Dobson models, which have been popular for years, have been taken over and even extended considerably. First of all, of course, the very good decomposability and transportability should be mentioned. Set-up and dismantling can be carried out without tools. The main and secondary mirrors are adjustable during the observation and only two adjusting screws have to be moved. Thanks to the use of precision ball-heads in the main mirror cell and a precision hinge for secondary mirror suppport, the adjustment is absolutely easy and guarantees excellent stability. All connecting parts of the tube trusses now consist of CNC machined aluminum and are attached by stainless steel dowel screws. The secondary mirror can now also be adjusted by the adjusting screws in the direction of the optical axis. The tried and tested 2.5’’ HEXAFOC focuser with 1:10 fine adjustment has been used for years - this allows vignetting-free observation despite the fast aperture ratio. A second 40° displaced installed mounting plate with a viewfinder shoe allows the rotation of the tube top in combination with a favorable position of the viewfinder tube or the mounting of an additional TELRAD viewfinder. The 6 supporting feet underneath the rockerbox offer a perfect stability and guarantee a smooth tracking in azimuth. Four smaller fans are installed in the side of the mirror box as well as a large fan is installed under the main mirror. This allows an even quicker adaptation to the ambient temperature and reduces the tube seeing (boundary layer removal). The lateral altitude wheels can now be stowed comfortably in the foam layers of the mirror box. Last but not least another gimmick: The optical tube and the mirror cell are designed to use also on heavy equatorial mounts.
