EXPLORE SCIENTIFIC 2" Variable Polarizing Filter
Universally usable variable polarizing filter with a  2" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 2.0" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing2.0" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

BRESSER Messier NT-203s/800 EXOS 2 GOTO Telescope
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.In the past few years the BRESSER Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the BRESSER NT-203s/800 with Hexafoc and fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2,5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale  leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Also prepared for use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism. BRESSER EXOS-2 GoTo Equatorial Mount. Mount, tripod and hand box with computer. This German mount has tracking motors in both axes that follow celestial objects very precisely. The handbox with GoTo works reliable and controls the mount in every situation. Precise ball bearings in both axes ensures minimal backlash at all nine possible tracking speeds. The battery pack (12 V) is conveniently fastened to the tripod shelf and takes eight size D batteries. The mount rests on a very tough and rigid stainless steel tripod and can take optical tubes of up to 13 kg. GOTO Stargazing at the push of a button ! The Startracker GoTo System enables beginners to start astronomical observations in just a few minutes, and guides you to objects that are hard to localize through a standard finder scope.Just push the button and the GoTo System will find planets, nebulae or galaxies for you and position your telescope automatically and precise. The GoTo System database includes thousands of astronomical objects. The Messier mount with GoTo System allows you to observe without tedious searching, or image faint objects that are hard to find in a standard finder scope.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight.

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.In the past few years the Bresser Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the Bresser NT-203s/800 with Hexafoc and fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2,5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale  leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Also prepared for use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.Mount and Tripod. The BRESSER EXOS 2 is a rugged mount with high rigidity and precision tracking for visual observation and astrophotography. The tripod is extremely rigid to suppress vibrations really well. This model is very well machined and has an illuminated polar finder scope and precise graduated circles. A powered twoaxis control (BRESSER Exos Duo) or a GoTo-Kit is available as an optional extra. The BRESSER EXOS 2 can take the weight - depending on length and use of up to 13 kg. This allows you to use refractors of up to 152 mm aperture and mirror telescopes of up to 203 mm aperture.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.CHARCTERISTICS OPTICS Optical design: reflector telescopeMirror diameter: 203mm / focal length: 800mm / F/3.9Maximum recommended magnification: 406xTelescope for night and solar observing Very high quality Hexafoc focuser with 2.5" free inner diameter Diffraction limited optics with parabolic main mirror 8x50 straight through viewfinder with reticle Optimized finder socket for comfortable use Cradle rings with handle and integrated piggyback camera holder (1/4 thread) Smartphone adapter for celestial navigation included Dovetail plate with stainless steel rail Can be connected to SLR cameras (optional T2 ring required) 50.8mm (2) to 31.7mm (1,25) adapter with integrated T2 thread (T2-adapter ring for your camera is needed) Backfocus fully inward focused: 60mm 85mm secondary mirror for optimal illumination Large knobs for primary and secondary mirror adjustment Tube without accessories: 8.7 kg - Tube with all accessories mounted: 11.5 kgCHARACTERISTICS 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. 69cm / Max. 109.5cm ) 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: 19.3 kg Batteries: not includedSCOPE OF DELIVERY Optical tube 26mm Super Plössl eyepiece (31.7mm / 1.25") Integrated 31.7 mm and T2 adapter Prism rail with stainless steel clamping surface Adapter for 50.8 mm (2") eyepieces 8x50 optical viewfinder Rotatable star map Aperture solar filter Tube clamp with handle and camera holder Smartphone adapter for celestial navigation Adjustable polar finder scope with optional illumination Astronomy PC software Stellarium (via download) BRESSER EXOS-2 mount Stainless steel tube field tripod with accessory tray 2 x 4.5 kg counterweight
