Bresser Messier NT203s/800 OTA features a fast parabolic main mirror and a Hexafoc focuser. It is an excellent tool for astrophotography. This is an aluminum tube with a classical design. The large primary mirror of 203 mm diameter allows for delivering deeper images and a faster optical system. The 85 mm secondary mirror prevents vignetting. The excellent 2.5″ Hexafoc focuser makes focusing easy due to its large diameter and smoothness and shifting-free operation. You will love astrophotography with this optical tube. It is easy to take pictures due to the tube rings with a 44 mm universal standard dovetail and a high-end finderscope with a crosshair and laser-engraved scale.
