Bresser PN-208 208/812 Optical Tube

In the past few years the Bresser Newtonian 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 a fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images with the same exposure time, than an equivalent 8" f/5 system - due to its shorter focal length primary mirror delivering a faster optical system. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2.5" Hexafoc focuser also prevents vignetting due to its large diameter and makes focusing a joy - the smoothness and image shift-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 make this system extremely comprehensive - 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) with the minimum of fuss. This telescope is ready to use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.
