Is anyone here who has one or even both scopes (TSN-1 and TSN-3) or it's counterpart with a straight eyepiece in use and would like to provide some pictures taken through these scope to show any difference in quality.
As far as I understand is that the TSN-3 is the upgrade version of the TSN-1 with fluorid coated lenses.
