After looking at this image, does it seem like the scope is in good collimation? You can see the obvious coma in the corners. This was taken with a 50D prime focus.

If this was taken at prime focus, then why are the stars 6 sided and not round?

The center of the optical axis near the top right corner of M27. I put a yellow cross on it, but the image looks like it did't come out so good.
