After that it largely comes down to seeing for the amount of detail that you can pick up. Your stars look great but there may be a bit too much noise reduction showing in the galaxy itself; it might be blurring some of the details but then again, not so great seeing destroys that too!
All in all, a great shot Paul  |
Thanks Colin. There wasn't too much noise reduction applied to the galaxy core - I think the limited detail was just the bad seeing. Some nights were up to about 4.5" FWHM and yet I still used that data (I know!). (One night the average FWHM of some frames was well under 2", with the stars in the centre about 1.5". I've never seen seeing that good before. Shame it was only for a bit of a night!).
