From my limited experience with the University Optics orthos (with no
direct comparisons mind you) I would say that they are comparable in
quality and at a fraction of the cost.
BTW, I didn't address the field of view issue regarding Naglers vs. orthos
when used with Dobsonian mounted scopes since the original poster had
already mentioned it. I suppose I should have discussed the effects of
fully multi-coated lens elements as Jeff Medkeff did later.
To compound things further planetary imager extraordinare Don Parker swears
by Naglers for planetary observing!
