Hi Fox,

That's a bit of a loaded comment. I have used both the TV85 and the TMB80 (not at the same time) and I "personally" felt the TMB80 was a better telescope than the TV85. We are comparing slightly different animals with the TMB being a flourite APO triplet and the TV85 being a non flourite APO doublet. The TMB also has a much nicer focuser for visual use in the dual speed Feathertouch. The TMB also has less false colour than the TV85, which is itself very good for colour correction.

At the end of the day it really is all a bit academic at this small aperture. Any differences between the top end scopes appear to reduce as the aperture is reduced IMO. Don't forget we are talking about a telescope of the same aperture as the finderscope on the two 25" Obsessions I regularly use. Put another way, does it really matter a whole lot if one is a tick better than the other because an 80mm telescope doesn't show a lot for visual astronomy anyway. Are you really going to see that much more in a Televue 85 than you will in a Williams Optics 90mm or a TMB80? Somehow, I don't think so.

Cheers,
John B
