I was under the impression that long ago UO made a 25MM Super Erfle. I have the 16MM & 20MM and have been trying for sometime to acquire a 25MM. Perhaps they did not make a 25MM? Thanks for your comments.

UO did make these. I have one. Not giving it up though as I have the whole set. Here's what UO site said about them:
"A major improvement on an old favorite! Using the latest in computer-aided design programs and high refractive index glass, the new Super Erfle gives significant improvements in both central and edge-of-field definition. The Erfle design is a true “classic” and the first quality eyepiece I ever owned years ago was a 20mm from Unitron.
That’s all history now, and these new 5 element oculars will meet your most critical deep sky viewing needs. Legendary University multi-coatings improves image contrast. The 16mm and 20mm have a crisp 60 degree field and the 25mm a 58 degree field. Satin chrome brass 1-1/4” barrel threaded for filters."

If want them from UO's supplier and can live without the University name on them....they're available here at a decent exchange rate...

They're not listed, but they are available. Markus at APM sells them also(without the University name and the same supplier).
I've got the whole set coming to me. I want to compare them to the Konig set that I own. I once owned the 25mm and REALLY regret selling it.
