Although it's not quite as spectaular as Peter's stunning resolution image, here's 3.5 hours of LRGB (5 minute subs) through a 1500mm f3.6 scope with small pixels (QSI683). I suspect a large amount of the difference in the two images is due to seeing conditions and processing expertise though, so I don't think it's fair to draw too many conclusions!
