OK...since I have been corrected, ridiculed and educated ( none of which I expected on the optics forum...) I have a serious question.....
Since the 30mm tubes aren't what they are made out to be, do any makers put out a 50mm objective along with a 30mm tube that is actually a good match, and make everything work as it should?
I ask because I have a friend very much enamored by these "Hubble" scopes and I can't see where its gaining him any advantage.....
