Hmm, I tried using all different combinations of spacers on the Venus before it set and then the moon last night and the screen was just fuzzy and grey. Once I take the camera off of the OAG it shows that it is definitely picking up light.

Can anyone pick up any faults on the image train in my first post photo?
