That's an interesting point. I read this great thread a while ago where this guy knew all about the best black paints around. I wonder if I can find that again. I think it was on the Astrophysics Yahoo Group or perhaps the TEC. Blackboard black spray has been recommended on this site and I bought some recently to use. I'll post once I have about its performance.

Certainly some areas are worse than others. Fortunately the best imaging is at the zenith anyway.
