Oh wow!
It's vastly different isn't it. I just looked up the manufacturing date of the 600D vs 1100D, however, according to wiki they're both built in 2011.
Can the type of telescope or f ratio contribute to the difference in quality of the final image? I only ask because I use an SCT, which I've heard to be considered 'slow'.
What type of telescope did you use for that image?
