For many years Bresser Newtonian telescopes have become the standard workhorse for Deep Sky astrophotography, now the second generation of this telescope, the Bresser NT-203s/800 comes with an improved Hexafoc focusser and fast parabolic main mirror.

The Bresser NT-203s/800 f3.9 will deliver you much more detailed images at shorter exposures due to its oversized primary mirror and therefore faster optical system (f3.9, compared to standard f5 telescopes of this size). The large 85 mm secondary mirror also helps reduce vignetting for maximum optimal illumination of the target. The excellent 2,5" Hexafoc focuser also helps reduce vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets a new standard in this price class.

BRESSER EXOS-2 Equatorial Mount:
The Bresser EXOS-2 is a rugged German Equatorial Mount offering high rigidity and precision tracking for visual observation as well as astrophotography. The tripod is extremely sturdy and designed to suppress vibrations very well. As with all the Bressier Messier range, this mount is built to extremely high standards and comes with an illuminated polar finder scope and precise graduated circles for more accuracy and ease of use during polar alignement. - If you wish at a later stage to upgrade the mount to a full computerised GOTO system, a powered two axis GOTO-Kit is available as an optional extra. The EXOS-2 mounts is designed to take a max payload weight up to 13kg allowing you to use refractors of up to 152 mm aperture or mirror telescopes of up to 203 mm aperture.
