Kim Not sure if this will help at all but below the calculator they discuss TLM vs TLM surface brightness and the impact of seeing conditions and magnification on said object. 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?
