The Vesta Pro 680k seems to be working better now I fixed a loose connection on it's ccd (I always wondered where the huge amp-glow was comming from in the raw images. Now I know).

Shown is a stack of 90 images of 10 seconds each made with the 680k in prime focus of the Starfinder 10". There was quite a lot of fog, and streetlights were right under this object, so conditions were far from perfect.
