That's a very pleasing result Dave, lovely clarity, particularly given where you have shot it from! Some good details revealed and a nice delineation in colours between the galaxies too, nice job
Yes, shooting that same scene, for the same exposure, from a true dark sky site, would yield a truly amazing result I recon
. NGC 2628 always reminds more of a foot long Subway sandwich, or one of those long sandwiches from a New York Italian Deli, than a hamburger....a Hamburger is Cen A's doppelganger to me
