Hi all, last night I tried for comet Metcalf/Brewington and missed the FOV with the Astrograph. Thought I would still process the stack of exposures to see what I had. Well at the exact postion of galaxy PGC3097159 there is this red object. That galaxy is listed in The Sky6 pro at magnitude 30 and size=0". So way too faint and small to show up here. I thought is may be a nebula, but nothing in my program.
I am sure it is not camera noise as such a large red area hasn't shown up before with the Astro 40D.
Any sensible thoughts welcome.
