This image is made up from rather poor data taken from Images taken from 20131103 to 20131213, lots of the frames with slight trails and or taken in poor seeing conditions. But I thought I would see what I could get and it was a challenge but using PixInsight worked wonders and the result is far better than I thought it would be, so I have posted here. At some point, I may try again, but as there are lots of targets up there, It may be a while.

The reasons for the poor data are: Too windy, poor seeing, but most of all, an imbalanced mount. I had altered it which added extra weight, and no matter how I re-balanced it, it still drifted a bit. So I am currently modifying the mount to get this right, spending time on it now, will (I hope) reap rewards when taking images in the future.
