ngc2997 mono only - colour added

hi

was working up a new scope last night when the seeing settled below 2arc sec - best in a long time!. The new scope was nowhere near ready, so I threw the old trusty 200mm back together and aligned the bits more or less by eye in the hope I could get something before the seeing went back to normal. It was partially successful, but the scope ended up a fair way out of whack with a bit of astigmatism and some bad diffraction patterns - I had to tidy up the very messy bright stars in Startools (thanks Ivo) to get something postable.

Anyway, here is the best I could do with the luminance data - unlikely to get colour. Pity I did not have a proper system going for this lot - the seeing was great and the mount was tracking at about 0.3 arcsec RMS! Ah well... thanks for looking. Regards Ray

EDIT: added colour - the best I could get with diffraction issue.
