Ok good info thx Mike, so just as the 10mm sct vb, t2 prism were best for binoviewing the baader lock ring and 2" clicklock diagonal are best for 2" eyepieces. This is why Eddgie kept mentioning the fastest way to switch from bv to 2" ep's....
Well, my well has dried up and will venture down the 2" path at a later time...
As for the binoviewers, you will be switching back and forth? Your T2 will be strictly for binoviewing?
I've decided not to bother with binoviewing my Cats or refractors. I did use the special WO adapter for binoviewing the Moon with my EdgeHD 8" for one observing session. But the WO adapter became stuck tight in another adapter that I needed to adjust the position of the binoviewer on the diagonal. (I'd have to look up what adapter that was. I don't memorize these things.) I had a devil of a time getting it unstuck. I don't think I'll revisit that setup again.
I'm not married to the binoviewer. I can take it or leave. For grab-n-go sessions and for deep sky I'd rather leave it. IME, binoviewing seems best for larger Dobs, and that only for planet/lunar. Otherwise I'd rather do without it.
