Description

Welcome to the world of undersampling ;)
Finally i found a way to connect my Canon telephoto lens (70-200 f4) and an USB filter wheel to my CCD camera (yes, with the correct chip distance ;) ).
Surprisingly there was a hole in the clouds on the same evening ;)
I was able to capture 6 frames a 600s (@70mm F5,6) before the clouds returned.

Only minor image processing, just a little bit of stretching. The image shows full resolution and the full fov.
