The 22T4 has a substantially wider field of view vs. the 22LVW. The latter is sharper than the former without a Paracorr, but since I recently acquired a Paracorr, I'm taking a second look at the 22T4.
The 22LVW also doesn't get along too well with a Paracorr. You need even more in-travel in 1.25"-mode than you do with a 14mm or 17.3mm Delos. The 22T4 can be set on the "5" setting of the older Type-1 Paracorr that I have and it works great.
I tried Syed's 22T4 out and it really had that certain, "oomph"--a wide field of view, a 3.9mm exit pupil that's great for wide objects, yet maintains more sky contrast than a lower-power ocular.
i did that move 1 month ago and i am very satisfied. the instajust is tigth and does not slip. very immersive and very nice with a paracorr.
i use much less the longer FL EPs now that i have the 22t4.
still need to try it on my f/7 refractor, but in a sct and a dob with a paracorr, it is a great combo
