This noble telescope has 8 lenses in 4 groups. All lenses are spherical and multi-coated. The good imaging performance is shown in high MTF values at 100Lp / mm. The star image results in round spots in the entire image field. The built-in temperature compensation is effective up to 4° Kelvin with 9 µm pixels.
The telescope is mounted in pipe clamps on a 3" dovetail rail.
