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. Features: Aperture: 203 mm Focal length: 800 mm Focal ratio: f/3.9 Backfocus fully inward focused: 60 mm 85 mm secondary mirror for optimal illumination Diffraction limited optics with parabolic main mirror Large knobs for primary and secondary mirror adjustment The kit includes: Aluminum tube with optics Tube rings with a handle and camera mounting feature 8x50 finderscope with a reticle 26 mm Super Plössl Find an interesting review on telescopes for kids here.
