Mine was very nice as well. I think optically they are very high quality.
To Don's point about undersized primaries, that well could be the case. While I loved the sharp images of my Orion, it was noticeable less bright at the same magnification on the same targets than one of my observing buddies' C6 XLTs. I never thought to use a laser to try and verify the vignetting.
Regards,
Jim
