27x120s on a G11 with QHY8 on C11 at prime focus, autoguided with PHD and QHY5 with meade OAG adaptor and capture in Nebulosity 2. Stacked in CCD Stack and processed in PS3.
Took this last night before the moon rise to test all my "bits and pieces" on a C11 I have on loan. Imaging at that FL is a bit scary at first. Everything is magnified and seems to "jump" all over the place. Goto and finding objects is a bit of a challenge too.
I'm used to image at 650mm FL maximum so that was a bit of a shock. The processing part is great though coz there are so many pixels in the stars to play with

Focus is soft. No mask yet so I eyeballed it
... and the camera is not exactly square either (see right of the frame) but the tracking is sorted out.
So overall I was happy with a pretty picture and having heard a few rumors about imaging with SCTs I can now see some real potential in the scope once working around a few things.
Hope you like it.
