Love wide fields cause the mount is usually up to it unguided so I can look thru the 12 inch while getting captures, but I took a few at low ISO (200 lowest for 600 seconds) and 400 at 1200 seconds all guided in a fashion one would employ on the Horsehead. And yes guiding makes all the difference as does a near perfect polar align. Used canon unmodified 300d piggy backed and guided with a 70 x 600 ar with illuminated reticle all on a eq5 mount (which runs near perfect now only taken two years) the shot was cropped to remove the amp glow off the right hand side, minimal processing and here is my result. Colour is a problem for me and is adjusted to get detail not the correct colour..or I am colour bind in plain terms
