Teleskops Bresser Reflektor 203/800 EXOS 2 GOTO

BRESSER Reflektor 203/800 EXOS 2 GOTO

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 steel tripod and can take optical tubes of up to 13 kg. GOTO Stargazing at the push of a button !
