I had a two-hour run on the DSC last night, Oct 01. At the
start of the run, I took a focus frame and noticed that
the out-of-focus images were NOT "centered": they have the
form of a diffuse ring with a bright spot at one edge.
I suspect that the telescope may not be properly collimated.
Has anyone else noticed this problem lately?
