Here I imaged the area around B39, the dark nebula the image center. There are a couple more dark nebulas in the top right, and bright nebula NGC2264 on the left hand side.

The focus must have shifted between this image and the previous image. AAAARG!!! I ended up doing some deconvolving in CCDStack, but at 100% it is still quite apparent that the focus is off. I'll check focus between target from now on.
