EXPLORE SCIENTIFIC Adaptor for 2" FT-Focuser on tubes with 2.5" HEX

Giant binoculars for observing the starry sky, nature and landscape. Observe the beauty of the starry sky at night and distant objects in nature during the day. Globular star clusters, glowing gas nebulae, the moon with its craters and even planets can be observed wonderfully on a clear night. But also all other distant things in nature and landscape, even ships and airplanes can be seen in detail. With the all-round binoculars of the EXPLORE SCIENTIFIC BT series, you can get up very close. Thanks to the large, light-gathering lenses and the professional coatings on all lens surfaces, these binoculars produce bright and brilliant images even at night and at twilight, providing a special viewing pleasure. The comfortable 45 degree viewing angle allows fatigue-free use even when the binoculars are tilted strongly.  Large binoculars can also be called a double refractor telescope One complete lens telescope with the full light gathering power is available per eye. Experience a whole new dimension of observing. Objects are reproduced almost vividly in these binoculars and observing with both eyes is basically very relaxed. Last but not least, this comfortable way of observation increases the recognition of the finest details and effectively prevents rapid eye fatigue. Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen  The BT series binoculars are designed for tough outdoor use. The IPX6 sealed and nitrogen-filled design effectively prevents fogging of the internal optics even under difficult weather conditions. The very light magnesium housing saves weight and makes it easy to handle. Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included. EXPLORE SCIENTIFIC is an established manufacturer of extremely high-quality eyepieces in the astronomy scene. An optical system is only as good as its weakest component. Therefore we have decided to deliver these giant binoculars with a pair of quality eyepieces of the 62 degree LER series. With an apparent field of view of 62 degrees and a focal length of 20mm, the BT-100 binoculars produce a 28x magnification. Thus these wide angle eyepieces offer a very good overview (field of view 2,3 degree) at moderate magnification. The large interpupillary distance of these LER (long eye relief) eyepieces of 15mm and soft silicone eyecups, which can be turned inside out, also guarantee a comfortable and relaxed view. For astronomy, a flat and sharp image field is advantageous and offers a particularly impressive viewing experience even during the day. Due to the waterproof design and the argon filling, these eyepieces are absolutely durable and easy to clean. Interchangeable eyepieces with 1.25 inch / 31.7mm plug-in diameter Adjust the magnification and field of view to your individual needs and choose from a wide range of available eyepieces. All eyepiece types with a plug-in diameter of 1.25 inch / 31.7mm can be used with the binoculars of the BT series. Especially recommended are EXPLORE SCIENTIFIC eyepieces of the 62 and 82 degree series with focal lengths from 8 to 26mm (see item No. 02188xx and 02196xx). The magnification can be varied from 21x to 70x (focal length binoculars : focal length eyepiece = magnification). The eyepieces are held in the binoculars by a precise brass compression ring clamp and guarantee a tilt free position.  Use of color and nebula filters for astronomical observations Increase the contrast and visibility of objects and details by screwing the corresponding filters directly into the thread of the eyepiece sleeves. The use of color and nebula filters must of course always be done in pairs. Suitable are all EXPLORE SCIENTIFIC screw filters with 1.25inch / 31.7mm diameter (see item No. 03102xx)  Comfortable 45 degree view and helical single focus The 45-degree viewing angle allows a relaxed observation position even when the binoculars are tilted strongly. Also the individual interpupillary distance can be adjusted in a range from 54 to 76mm. With the fine helical individual focusing, precise focusing is achieved effortlessly. Extendable dew caps The integrated dew caps can be removed in high humidity and cold conditions. This avoids fogging of the outer objective lenses and effectively shields additional control light coming in from the side. Integrated carrying handle A metal carrying handle located at the center of gravity facilitates transport and ensures a secure hold during tripod assembly. Suitable tripods and tripod connectionWhen using these large binoculars, a sturdy photo tripod with an appropriate load capacity is highly recommended. The connection is made via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) in the tripod adapter of the binoculars. The ideal solution is to use the optional availlable EXPLORE SCIENTIFIC U-Mount with field tripod (item No. 0114300). This is specially designed for the large binoculars of the BT series and carries these devices absolutely safely. The excellent mechanism with adjustable friction in both axes allows easy moving and tracking. The binocular position is kept stable depending on the adjusted friction intensity. Vibrations are reduced to a minimum by the massive construction of the U-Mount and the large stainless steel tripod. Even at high magnification there are no vibrations and the finest details can be observed.FEATURES Large binoculars for observing the starry sky, nature and landscape Observe globular star clusters, glowing gas nebulae, the moon with its craters and even planets Also wild animals, ships and airplanes can be seen in detail Highly light gathering lenses produce a bright and high-contrast image All-round binoculars, but especially suitable in twilight and at night The comfortable 45 degree viewing angle allows fatigue-free use One complete lens telescope with the full light gathering power is available per eye Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included 28x magnification and an apparent field of view of 62 degrees, true visible field of 2,3 degreesLarge interpupillary distance of 15mm to the eyepiece lens for comfortable viewing Eyepieces interchangeable and with standardized plug-in diameter of 1.25 inch / 31.7mm The magnification can be adjusted with optional eyepieces from 21x to 70x Precise brass eyepiece compression ring clamps for tilt-free fitColor and nebula filters can be used for astronomical observations Extendable dew caps prevent fogging of the outer objective lenses and stray light Integrated carrying handle facilitates transport and mounting on the tripod Tripod connection via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) Tripod recommendation: EXPLORE SCIENTIFIC U-mount with field tripod (Art.No. 0114300) Objective type: Air spaced achromatic lens (2 elements/ 1 group) Coating: full multilayer coating on all optical surfaces Aperture, focal length and aperture ratio: 100mm / 550mm / F=5.5 Sealed to IPX6 standard and nitrogen filled: yes / yes Close focus distance: 25 meters Eyepiece mount diameter: 1.25'' / 31.7mm Adjustable interpupillary distance: 54 to 76 mm Helical single focus: yes BAK-4 prism system for a bright and high-contrast imageDimensions and weight of binoculars: 520 x 270 x 155mm, 6.8kg Housing color of binoculars:  white SCOPE OF DELIVERY Giant binoculars with carrying handle (without tripod)Eyepieces ES 20mm 62 degrees LER Series (2pcs)Precisely fitting foam insert for transport Dust covers for objectives and eyepiece sockets Instruction manual

Enter the world of astrophotography now - with the new EXPLORE SCIENTIFIC 4K DEEP SKY ASTRO Camera including ST4 autoguider function. This is truly new: Equipped with the new high-sensitive SONY IMX585 Exmor CMOS colour sensor, this astronomy camera delivers amazing image results with extremely short exposure times even with basic telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with an SLR or CCD astro camera. An all-round camera that delivers super-sharp and high-resolution planetary images. The high 4K resolution of 3840x2160 pixels guarantees the best possible image result. Sensor The secret to the high light sensitivity is SONY's new back illuminated Exmor CMOS sensor. It increases the quantum efficiency to up to 77 % at 533 nm, which leads to an extremely high light sensitivity and thus particularly bright and high-contrast photos. In addition, the particularly low noise level of this new CMOS sensor generation by SONY ensures exceptionally high brilliance and no active cooling is required. Nevertheless, this astro camera has an elaborate internal structure made of aluminium for ideal heat radiation and a fan that can be switched on via software. When used with suitable telescopes, the high native pixel resolution of 3840x2160 enables very nice overview images of the moon, but also detailed planetary images. Solar Imaging This camera is also recommended for solar astro-photography. Especially the Lunt LS40 THa solar telescopes (item No. 0551145/0551146/0551147), with their short focal length, allow in combination with this planetary camera with its large sensor great overview images of the sun. Important Note: When observing and taking photos of the sun, always use a suitable protective solar filter or a special solar telescope. Otherwise there is a risk of immediate blindness and damage to the camera. Software The included Explore Capture professional software offers not only the necessary basic functions for image and video capture, but also many helpful special functions for image post-processing and for setting up the guider. Functions such as live image display, exposure settings, white balance, dark image capture, stacking, timelapse recording and much more can be configured individually. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings you can produce absolutely presentable results without a lot of prior knowledge. And when you are ready, simply switch off the automatic settings and gradually venture into the individual professional settings. Automatic tracking control Connect the camera directly to the ST4 port of your telescope mount and you have a fully automatic tracking control. Thus, long exposures of several minutes are possible without the stars producing unwanted star traces due to the always existing periodic error of the telescope mount gears. A corresponding ST-4 connection cable is even included in the camera's scope of delivery. Because of the high light sensitivity of the camera, you will always find a suitable guide star even with very short exposure times. Simple automatic tracking at its best. Connection For the connection to telescopes, guiding scopes or off-axis guiders the camera has a 1.25'' socket with 1.25'' filter thread (M28.5x0.6) and a large T2 connection thread (M42x0.75) directly on the housing. IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10 or 11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, GuideDog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

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.
