Explore Scientific ReflexSight LED Finder
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

EXPLORE SCIENTIFIC 8x50 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection
Universal 50mm viewfinder and guide telescope with a focal length of 220mmExcellent 8x50 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. 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 8x50 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 8x50 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.96 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=1 degree) on the crosshairs 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 8x to 40x 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 8x50 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 220mmMax. 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 6.96 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 1.0 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 8x to 40x 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 tipsSCOPE OF DELIVERY8x50 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

EXPLORE SCIENTIFIC BT-70 SF Giant Binoculars with 62° LER Eyepieces 20mm
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-70 binoculars produce a 20x magnification. Thus these wide angle eyepieces offer a very good overview (field of view 3,1 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 15x to 50x (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 20x magnification and an apparent field of view of 62 degrees, true visible field of 3,1 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 15x to 50x 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: 70mm / 400mm / F=5.7 Sealed to IPX6 standard and nitrogen filled: yes / yes Close focus distance: 12 meters Eyepiece mount diameter: 1.25'' / 31.7mm Adjustable interpupillary distance: 54 to 76 mm Helical single focus: yesBAK-4 prism system for a bright and high-contrast image Dimensions and weight of binoculars: 370 x 213 x 122mm, 3.4kg 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

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.

EXPLORE SCIENTIFIC 10x60 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection
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

EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
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

Explore Scientific ReflexSight LED Finder
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

EXPLORE SCIENTIFIC 8x50 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection
Universal 50mm viewfinder and guide telescope with a focal length of 220mmExcellent 8x50 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. 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 8x50 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 8x50 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.96 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=1 degree) on the crosshairs 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 8x to 40x 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 8x50 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 220mmMax. 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 6.96 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 1.0 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 8x to 40x 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 tipsSCOPE OF DELIVERY8x50 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

Vixen finder scope 7x50 with crosshairs and illumination
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
