While I think my shots are pretty good for a small amateur scope, if you want to see a shot almost as good as Hubble with what is (just) still an amateur instrument, have a look at Johannes Schedlers site, scroll down to his Eta shot taken on 17 May 2008 under excellent seeing conditions in Namibia FWHM = 1" with a superb Philip Keller 20" cassegrain
Check out the lasrgest files, they are simply breathtaking

There are always better shots out there
