Description

First image with the 294MC-Pro and the 8"RC. I had some odd reflections that I think were caused by the ONAG. Basically above and below each bright star was a oval donut. Looked like a out of focus star. Not many of them, but I stamped them out in PS. Strangle, the background pattern that plagued my M51 and M101 image with the 8"RC @ f6 was a non-factor for this image.
