Wished I had a 12" aperture scope.
This is the best I could do with my 10" SCT.
Very nice pics of M13 and M42! I'll guess that you have a Meade SCT? I worked at Celestron many years ago, and have owned a handful of different Celestron scopes. Right now I have a homemade 14.5" F5.5 Newtonian, optimized for planetary viewing... curved vane spider, 2.1" secondary & a very low profile focuser. It's on a Dobsonian mount (sono-tube) and an equatorial platform. Unfortunately it's just not rigged at all for photography. I'd have to move the mirror forward about 4-6 inches to get it to focus a camera. (Range of focus is one of the beautiful things about SCT scopes)
Where do you do your observing?
