Description

Test for the Skywatcher Esprit 100/550 in combination with 0,75x Riccardi Reducer, at f/4,1 or 412mm focal length. The chip size of my G2-8300, approximately APS-C, is well corrected. The fine resolution of the system can only be appreciated in the 100% version of the picture, give it a try! Even the 150% version looks crisp, but over 100MB size... download here:
