i didn't really know what i was doing then, and am sure that i could get much better results. mostly these are only a few mins total exposure with no calibration frames except darks.

If you get flats, etc going and up the total exposures i can't see why you can't do way better.

there was a bit of a sweet spot in terms of the angle the scope was pointing (zenith is no good).


cheers
