Bill, is the 92SS of similar build and visual quality?
Would put its build quality a notch lower than the TV as TVs are built like tanks. But the build is still excellent on the TMB. Optically I would say they are all very good. TV85 is a doublet and some folks report they can coax a very little color out of now and then. NP101 essentially color-free. TMB had a little color as it is a super-fast triplet. NP would be a more complicated re-collimation given it's dual doublet design, other two perhaps a bit simpler if needed (TMB is meant for user collimation, TVs are built for it to be done at factory).
NP is really in a class of its own and should IMO be considered as such due to its optical design - Petzval. It produces a flat field whereas doublets and triplets do not. You might gets some field curvature visible at the eyepiece for low power ultrawides with the TMB, not with the NP. If optical performance were the ONLY deciding factor then would go with the NP as it has the unique flat field, very fast focal ratio. But since portability and simplicity are prominent goals for you, and aperture as well to some degree, the others come into the mix. For me, if just a choice between the 85 and the 92, I would go with the 92 because smaller and wider field and more aperture...simply more versatile than the 85. Plus the TMB92 (not the L version) has Starlight focuser which puts most focusers to shame, and still $350 less than the 85. If you go with the L version then $850 less than the 85. So could get the 92L with a battery of fine eyepieces and have more TFOV and more aperture than just the 85. To me, the choice is between the 92SS and the NP101. If I was going to make the refractor I buy my only largest refractor, then would probably opt for the NP101 if could afford. If I anticipated getting a 120mm or 130mm APO in the future, then that would steer me directly to the 92 as would never need an 80mm for travel since the 92 is so very small and a 101 is IMO just too big to keep with a 120 or 130 APO also. It is s always more about other things than purely optics.
