Product information "BRESSER Polar Viewfinder EXOS-1"
Optical pole finder scope for fast and precise polar alignment of the BRESSER EXOS-1 EQ mount (part No. 4964200).
The BRESSER Polar Viewfinder is used with the BRESSER EXOS-1 EQ mount enabling high precision alignment to the celestial pole by using the illuminated reticle and star constellation markings. Simply adjust the pole height and azimuth until the constellation markings in the polar finder match the constellations in the sky - that's it. Ideal for optimizing tracking accuracy in astrophotography.
A new take on a classic design, superior to the usual red dot finder - which will fit many telescopes and larger binoculars.Explore Scientific ReflexSight™ LED projection viewfinder, uses proven functionality with versatility, while having enhanced performance features.Looking through this viewfinder shows multiple deep red target circles projected against the night sky. Both eyes can be used for quick and easy star hopping, in order to target objects in your telescope. The big advantage is that you can see the entire night sky without magnification and not just a small section of the sky, as you would through a magnified finderscope. This makes Goto aligning quick and easy and speeds up acquisition of targets.New "Multi-Dot" target circle pattern (in standard circle diameters of 4.0 degrees, 2.0 degrees and 0.5 degrees), prevents blocking of stars within the field of view. Using the widths of the projected circles as reference points allows those users with non-goto telescopes to easily work out the location of non-visible targets, with reference to more easily visible stars. The projection screen size is a generous 55 x 35 mm.Multiple mounting options. The Explore Scientific ReflexSight™ LED projection viewfinder's base fits standard "Vixen-style dovetail" finder bases, allowing the user to attach this finder to a wife array of commercially-available telescopes, without modifying the telescope itself. A ¼ inch x 20G threaded adapter (photo tripod thread) is built into the finder base, allowing the finder to be attached to a variety of telescopes, via piggyback camera adapters with a photo tripod threaded hole.Functional design and intuitive use: the smooth housing, with no sharp corners, prevents snagging. Easily accessible battery compartment, taking 2x standard AAA alkaline batteries (not included), which power the frugal LED illuminator. The low power consumption of the LED lighting ensures a long operating time. Large, continuously adjustable brightness control with knurled knob head can be easily operated with gloves. Click the rotary switch to turn off completely. Rear-facing, tool-free three-point parallax knurled collimation knobs, again, easy to operate even with gloved hands, ensure you are well locked-on to the main optical axis of your telescope. The projection screen is coated, to minimise annoying reflections and allow you to concentrate on the finder's target and the night sky behind it. Comes complete with screen and optics cover. The extremely compact design allows mounting even on small, lightweight telescopes - truly a finder for all!FEATURESReflexSight LED projection finder with deep red target circles Standard circle diameters 4.0 degrees, 2.0 degrees and 0.5 degreesProjection screen size: 55 x 35 mmFits standard Vixen-style dovetail finder shoes There is also a ¼ inch x 20G female photo tripod thread in the base Can be mounted via piggyback camera adapters etc. Operates on standard AAA batteries (not included) Smooth housing with no sharp corners, prevents snagging Comes complete with optics and screen cover Compact design and easily accessible battery compartment Large, continuously adjustable brightness control with knurled knob Click switch to turn off completely Tool-free three-point collimation parallax adjustment with easily accessible knurled knobs Can also be mounted on small and light telescopes WHAT'S INCLUDEDReflexSight LED projection finder

The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope
Thanks to the large aperture of 50 mm, the Vixen 7x50 finder scope immediately reveals many objects that are not visible in smaller viewfinders. This makes it easy to adjust the telescope to the target object. The red illumination of the finder scope can be dimmed to different levels.The eyepiece is detachable (31.7 mm diameter) so that a CMOS camera with 31.7 mm diameter (available separately) can be attached and used as an autoguider. The eyepiece unit with crosshairs is also removable in order to use 31.7 mm diameter eyepieces (sold separately) with different focal lengths. This allows the finder scope to be operated with various magnifications.The lens is designed to be compatible with CMOS cameras. The distance between the bottom of the 31.7 mm sleeve on the camera side and the sensor surface should be approximately 17 mm. However, the focus position may vary depending on the camera, so you should adjust the guiding camera for focus before use. The focus of the optics is adjusted by rotating the lens. First, the black lock ring on the main optics must be loosened. Then, the focus can be adjusted by turning the lens mount. Please also read the operating instructions for the viewfinder and the CMOS camera used.If the focus of the viewfinder has been adjusted, the focus position must be readjusted when using the eyepiece unit.FEATURESMagnification: 7xAperture: 50 mmLenses: coatedCrosshairs: illuminated in red, dimmableDimensions: 220 mm × Ø 58 mmWeight: 467 gSCOPE OF DELIVERY7x50 viewfinderEyepiece unit with illuminationCR2032 batteryInstruction manual

Universal 60mm viewfinder and guide telescope with a focal length of 250mmExcellent 10x60
viewfinder telescope with removable eyepiece unit and crosshairs with
adjustable red illumination. The larger aperture and focal length, provide an even brighter field of view and more accurate tracking due to the higher resolution. The precise helical focuser and the 1.25
inch /31.7mm plug-in connection, as well as the T2 camera connection
thread (M42x0.75mm), allow the autoguiding required for long time
exposure to obtain a point-shaped star image. It can also be used as a
mini travel telescope.High quality 10x60 viewfinder telescope with adjustable crosshair illuminationImage
sharpness and viewing characteristics lift this viewfinder well above
the level of the usual 10x60 viewfinder scopes. The visible image is
bright and crisply sharp. Furthermore, this viewfinder has a very large
field of view (FOV) of 6.0 degrees. This makes finding and adjusting
objects much easier. The existing scale markings (pitch=0.85 degree) on the
crosshair are a good reference for estimating distances, and the open
centre markings also make it easier to centre objects precisely. All
lens surfaces are protected against weathering by multi-coating and
guarantee a bright viewfinder image due to the high light transmission
values. The adjustable red LED illumination unit is powered by two LR41
coin batteries. The main lens and the crosshairs can be focused
independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne
of the main applications for this telescope is the so-called
autoguiding. Here the usually larger photo-taking optics are actively
corrected by a smaller guiding telescope with a second tracking camera.
This means that the mechanical fluctuations in the tracking accuracy,
which are present in all astronomical telescope mounts, are measured by
the tracking camera and compensated accordingly. This is necessary in
order to obtain a point-shaped star image on the astrophotos during long
time exposures and to avoid unwanted star trails. For this purpose, the
guiding telescope is inserted into the existing viewfinder shoe of the
photo-taking optics and aligned parallel. If the existing viewfinder
shoe is not compatible, a suitable viewfinder shoe is also included.
With the 1.25 inch / 31,7mm plug connection at the rear end or via T2
thread connection (M42x0,75mm), a tracking camera can be mounted
afterwards. This is held securely by a brass ring clamp and 3 clamping
screws. Please note the required back focus for your tracking camera.
The focal plane (backfocus) is approx. 22mm behind the T2 thread. The
sensitive focusing on the guiding star is done by a large knurled wheel
of the mechanically precise manufactured helical focuser. For easy
reproduction of the point of focus, this has a white millimetre scale
from 0 to 28mm, which is attached by laser engraving. After the tracking
camera has been connected directly or via computer to the telescope
mount and the necessary basic settings have been made, the first
astrophotos with long time exposure can be taken.Use as mini travel telescopeThis
viewfinder and guide telescope can also be used quite simply as a mini
travel telescope. With the optional eyepieces, a magnification of 9x to 50x can be achieved. Nearly all eyepieces with a focal length of 5 to
26mm and 1.25 inch/31.7mm plug connection are suitable. Especially
recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art.
02195xx) and 62 degree (02196xx) LER series. Note: Only straight view
use is possible.Metal viewfinder holder and viewfinder shoeThe
mount of this viewfinder and guide telescope is completely made of
aluminium and is a stable base. The viewfinder mount is suitable for
many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER
MESSIER etc. If the existing viewfinder shoe is not compatible, a
matching viewfinder shoe is also included. This can be attached to the
telescopic tube by means of four M5 screws. The bore distances of the
viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The
six large adjustment screws with non-slip knurling make it easy to align
the viewfinder, even with clammy fingers. All adjusting and clamping
screws have plastic tips that effectively prevent the viewfinder housing
and viewfinder mount from being scratched.FEATURESExcellent 10x60 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 250mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.0 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 0,85 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 9x to 50x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsWHAT'S INCLUDED10x60 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

The Vixen POLARIE is a new camera accessory, that enables you to capture sharp, point-like images of the stars. It has been developed to track the stars and to compensate for the movement of the earth. POLARIE enables you to take atmospheric shots of landscapes and the night sky and can also capture these in sharp images. Extremely simple and compact design for use in every location on earth.
If you have ever viewed a romantic, starry sky, you will surely have felt the desire to capture it on film. But if you have tried to do this, you will know that it’s really not all that easy. This is because you need to have multiple exposures of several minutes if you want to photograph the stars. As our earth is always turning on its axis, the stars keep moving as time passes and become long strokes on photographs. Today’s digital technology gives us the option of obtaining shorter exposure times by increasing the sensitivity of the sensor, but, unfortunately, this dramatically increases picture noise and the picture becomes very noisy and ugly. This makes it impossible to take beautiful images of the night sky. For this reason, the Vixen company has developed the Polarie Star Tracker, which eliminates the problem of star migration. When you attach your camera to the Polarie, the device will track in the opposite direction of earth’s rotation and this allows for sharp, point-like images of the starry sky even when using long exposure times.
POLARIE is a new and unique camera accessory for photographing the night sky, with perfectly point-like stars being tracked. Using the simplest solution, it makes the experience of photographing the night sky more accessible for everyone. The multi-functional mode dial is adjustable for sky- and landscape-, moon-, sun- and star-tracking. Polar altimeter for a fast focus. Also included: USB connection for external power supply and a built-in compass for quick orientation. Available as optional extra accessories are a polar finder telescope for exact alignment with the celestial pole for long-exposure photography including into the telephoto range, and a tripod.
