Description

Unfortunately all Flat frames shown some kind of problem. Also, due to a small misalignment and huge field curvature (probably Coma corrector at wrong distance and sensor tilt), the image has to be cropped.
With new variable distance spacer and tip-tilt adapter, this problem will be (hopefully) soon solved...
