BRESSER Viewfinder 8x50 without Holder for Messier Telescopes Category: Spare Part suitable for Messier Telescope Series Description: The high-quality 8x50 Viewfinder without Holder is a spare part for Messier Telescopes. It enables precise target alignment for untarnished observations and is easy to mount on the telescope viewfinder holder (Art. 4901630). Suitable for the BRESSER Messier Telescope series.

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

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.Due to the short focal length this telescope provides large and bright fields of view. Don't forget to observe the Anrdomeda Galaxy with the BRESSER Messier AR-127S! The glow of this object that you can observe from the immense distance of 2 million lightyears is as spectacular as it is to watch large nebulae with the Messier AR-127S. Because of the large aperture it is even possible to use nebular filters on the Messer AR-127S. These filters can enhance the appearance of emission nebulae to en astonishing contrast level.  The special four lens construction delivers a better perfomance than a classical two lens achromat of this focal length.The short tube and the rigid mount also make this combination ideal for short easy viewing sessions, especially if the telescope has to be moved for observation. CHARACTERISTICS OPTICSOptical design: refractor telescopeLens diameter: 127 mm / focal length: 635 mm / F/5Maximum recommended magnification: 254xTelescope for night and solar observationHigh-quality BRESSER refractor opticsUniversal telescope for planets, double stars, planetary nebulae and deep-skyHigh-end Hexafoc-focuser with 2,5" free inner diameterFour lens construction8x50 straight through viewfinder with reticleCradle rings with handle and integrated piggyback camera holder (1/4 thread)Smartphone camera adapter for sky navigation includedDovetail plate with stainless steel rail 50,8mm (2") to 31,7mm (1,25") adapter with integrated T2 thread (T2-adapter ring for your camera is needed) CHARACTERISTICS MOUNT Stable parallactic mount with fine drive in both axes Ball bearings in both axes for more precise movements Stable height adjustable stainless steel tripod (min. 69 cm / max. 109,5 cm ) Load capacity up to 13 kg payload Retrofittable with the BRESSER Star Tracker Goto Kit (item no. 4951750) Circular bubble for easy horizontal alignment Pole height scale for setting the latitude Scaled graduated circular rings to facilitate finding objects using a star atlas or planetarium software Pole finder scope with optional illumination ( item no. 4964212 ) Tripod weight: 4.7 kg Mount weight: 5.6 kg (without counterweight) Total weight incl. counterweight: 14.8 kg Batteries: not included SCOPE OF DELIVERYTelescopeAperture solar-filter26mm Super Plössl eyepiece (31.7mm / 1.25")50.8 mm (2) diagonal mirrorIntegrated 31.7 mm and T2 adapter 44mm Universal Dovetail (for EXOS and similar mounts) Handle with camera holder 8x50 ViewfinderSmartphone adapter for celestial navigationAdjustable polar finder scope with optional illumination Astronomy PC software Stellarium Rotatable star map1 x 4.5 kg counterweightEXOS 2 German equatorial mount with stainless steel tube field tripod
