Thanks, Jay. I did look at this site and a few others like it but I didn't have my question answered. However, as I've thought about it some more, I've begun to wonder if there is any correlation at all. Perhaps it is more a function of one's own visual acuity. But hey, someone out there has to have a more definitive answer, so I'm still "listening."

I'm sure those more verse in this will come along, just trying to see if that site has a quick answer for you. Oh, here is the site: http://www.stargazing.net/naa/scopemath.htm Jay On Sat, Apr 16, 2011 at 11:29 AM, Kim Hyatt <kimharch@cut.net> wrote:
I can't find information that relates a scope's theoretical limiting magnitude to a corresponding theoretical limiting magnitude based on surface brightness. Maybe I'm missing something that is obvious but I can't put my finger on it. Can anyone help?
