Very sharp though. Better than mine with a CDK17 at home.

Thanks, Greg. I'm not sure whether I might have managed to damage the stars somehow in the processing. When I did the PSF estimation for deconvolution I picked 60-70 stars and the average aspect ratio was up in the high 0.9s and there wasn't any consistency in rotation angle. That said, I'm sure my polar alignment wasn't perfect. I get so little time under dark skies that I don't spend a lot of time tweaking it. I'll see if I can fix the stars (and the black clipping) in my next repro attempt.

Thanks, Dave. I hope you're going to get some quality dark sky time once semester is over!
