EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
£61.00*
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 8x50 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection
£186.00*
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 ReflexSight LED Finder
£55.00*
£69.00*
(20.29% saved)
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

Vixen Polarscope PF-L II for AP & SX Mounts
£257.00*
Vixen’s latest design of polar finder, allows a simple, hassle-free method of polar alignment. The Vixen Polarscope PF-L II for AP & SX mounts has a reticule showing the Pole star (Polaris) and two other stars (Delta UMi and 51 Cep) in their precise positions. By turning the Polarscope you can easily match the reticle with the asterism of these stars in the sky and mechanically adjust your mount’s azimuth and altitude axes to align to the true North Pole. You can then adjust the Polar star to a more precise alignment using the reticule’s year marking (which runs from 2015 to 2040, but in practise can be used much longer after this) .
Using this alignment process, with visual reference to the actual stars in the sky, a complicated alignment, using date and time to calculate Polaris offset from the pole is unnecessary. For alignment in the Southern Hemisphere you simply use the Trapezium asterism (Sigma, Chi, Tau and Upsilon Octantis) of the constellation Octans and position the reticule with the trapezium stars aligned to their marked positions.
The Polarscope has built-in LED illumination, which is dimmable in many stages, and ensures an automatic shut-off after 2 minutes, saving your battery life.
The PFL-II also has an improved edge sharpness, when compared with its predecessor.

In the northern hemisphere*, simply position the polar star and two additional stars in the finder’s field of view so that each star is aligned with the corresponding positions in the finder reticle. This enables you to easily configure the equatorial mount with an accuracy of 3 arc minutes or less. The new design of the polar scope eyepiece improves the visibility of stars and makes the scale easier to read. *Three stars for polar orientation in the southern hemisphere are located in Octans.
What is the polar alignment scope?
The polar alignment scope is a small telescope that is installed parallel to the R.A. axis of an equatorial mount such that it matches the R.A. axis to be parallel in the direction of the diurnal motion of stars. The polar alignment scope utilizes 3 stars (Polaris, Delta UMi and 51 Cep) near the north celestial pole. To locate the north celestial pole, simply align the positions on the reticle in the polar alignment scope with the 3 designated stars. In addition, the patterns of the Big Dipper and Cassiopeia are engraved on the polar alignment reticle for use as a guide for the north celestial pole. The polar alignment scope can align the polar axis of the equatorial mount as accurately as 3 arc minutes or less.
The marks and patterns on the built-in reticle provide everything that you need for polar alignment
The necessary information for polar alignment is integrated into the reticle, which is designed for locating the north (or south) celestial pole. It is not necessary to configure an hour angle setting in the dark. This makes polar alignment easier, as you can look through the eyepiece of the polar alignment scope.
A free app is available to download via the following link.
https://www.vixen.co.jp/app/
Dark field illumination (with automatic power off function)
The switch on the polar alignment scope’s brightness adjustment dial illuminates the reticle in red when activated. Compared with bright field illumination, this prevents less bright stars from disappearing from the scope's field of view. The brightness can be adjusted in 8 levels by turning the brightness adjustment dial. The red light dims gradually after a certain period of time and turns off automatically.
Easy to set up
Remove the mounting block on the front side and the cap on the rear side of the POLARIE. Then insert the POLARIE PF-L finder scope into the POLARIE to complete the installation. The telescope is ready for use in no time!

Vixen finder scope 7x50 with crosshairs and illumination
£149.00*
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
