I felt optically inferior next to Daniels 17" scope. I'm sorry, make that SEVENTEEN AND A HALF inch scope. ;) What's a half inch among friends?
Actually, everyone forgets to subtract their edge bevel. Most folks are surprised to find that their clear aperture is sometimes almost 1/4" less than the stated size. My own, old, old 17.5" mirror has a clear aperture of ~17.35" when the bevel is subtracted. I'd be willing to bet that Daniels isn't a true 17.5" too. Hope that doesn't ruin his day. __________________________________ Do you Yahoo!? New and Improved Yahoo! Mail - 100MB free storage! http://promotions.yahoo.com/new_mail
