A month or so ago I finally got around to processing some data I took last November. The target was NGC 2146, a spiral galaxy in Camelopardalis undergoing some serious disruption. My data capture was problematic. Due to CCDCommander’s retention of prior settings when creating a script (this is not a bad feature), I took most of my luminance data binned 2×2. Probably not a bad idea as seeing wasn’t that great, but not what I had intended. In trying to recover from this error, I did not get adequate color data.

I did all of my alignment and combination processing in PixInsight, and had a good learning experience there. The main one is to make sure to use the optimize function on the darks. All in all, even with the data challenges, the image turned out OK.

Here is the final result:
