My most used is my green TV-85 as its so grab & go. Its also tough & works as a daytime spotter too.
My least used is my Tak TSA-120. It is my most expensive, needs a better mount, and "for best" use.
In-between, my 100 Equinox. Not quite g&g, but easy enough to set up on a Giro Ercole mount.
I'm the same. My (also green) TV-85 is most used for the much the same reasons.
My only other refractor is an NP-127, on a heavier mount, but does generally give best views.
Weight -- for grab and go the TV-85 is on a Manfrotto 475B + SV M2C,
-- NP-127 is on a Berlebach Planet + DM-6
The other reason the TV-85 is used more often is because it has slightly more back
focus than the NP-127, which surprised me. I roughly measured the TV-85 as 150mm
of back focus, and the NP-127 as 135mm? This is just enough difference so
- Baader T-2 Mirror diagonal
- T-2 Quick Changer
- Maxbright II with 1.7x GPC
- *Baader* Mark IV zoom
comes to focus with the TV-85, but not the NP-127. I think if I swapped in a prism
diagonal, the NP-127 will come to focus. Alternatively, Tele Vue "Group B" parfocal
EPs come to focus in both, so maybe I'll just do that.
