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.
