University Optics 32mm Konig with 1.25" barrel. Mint condition with box and caps. I bought this to try in an ETX-90, and it is fabulous--far superior to the 26mm Super Plossl, with over 1.3 degrees of true field in that scope and no dropoff in sharpness nor geometric distortion visible anywhere in the field. No ghosting. No problems. I guess it could use an aftermarket rubber eyecup of some kind.

Need some data on this eyepiece? The field stop is 32mm in diameter and located about 13.9mm above the flange (would be Tele Vue's F measurement of -.55", i.e. it needs about 0.8" more in-travel than a Radian or Tele Vue Plossl). The effective field stop diameter (barrel limited illumination) is about 29mm in the ETX (closer to 30mm in my 10" f/5). It weighs about a half pound.

So it's a nifty eyepiece, but I don't really need wide fields out of my ETX, so I'm thinking of something else for that little scope. Your turn.

$80 + $5 shipping via domestic USPS Priority Mail. PayPal or US Postal Money Orders preferred. (SOLD)
