Description

This is a comparison between C11 and the Sharpstar Astrograph.
Camera on the C11 was Nikon D750a and on the Sharpstar Nikon D5100a
Exposure time was both the same - scopes are side by side. The C11 was at a focal length of 2000mm which is with the reducer f 7, the Sharpstar´s focal length is only 640mm with corresponds to f 3,2.
Focus on the Sharpstar could have been a bit better, so there I miss a bit on resolution.
It´s interesting, that the small scope holds quite well against the C11.
