that said tho, some of the old models are pretty good, like the 20mm t2...
anyhow one modl of televue has been left out, the radians. I believe these have extra eye relief.
if you try bintels site they sell televue, or go a secondhand one. most amateur astronomers look after thier gear, especially when it gets to televue level so secondhand gear is 99% of the time in really good condition.
I have bought 2 premium level eyepieces second hand and i couldnt tell them from new
