Thanks!

Their orthoscopics were said to be quite good. However all my Criterion EP's are rubbish.

I almost didn't reply because I hate to be the bearer of evil tidings. But, then, I thought I might save yourself some regrets if you're thinking about buying some.

Over the years, I've owned a number of Criterion scopes, several of which (all Newtonians) were quite good, optically (don't even think about one of their SCT's!).
With these scopes came a large number of Criterion eyepieces. Without exception they ranged from "pure *Word deleted by the CN gnaughties gnomes*" (the Ramsdens, Kellner, etc.) to "just not very good" (Orthos).
Maybe there' someone out there whose experience is more positive...but I've never met that person.
Hope this helps!

Well, thanks for the info, even if bad. They happen to be just coming with an old RV-6 I bought. I wasn't really counting on quality but just a bit curious. I will hold on to them though for the collectible value of the RV-6.

I have 9mm and 18mm ARs that came with an RV-6 that I recently purchased. I don't use em much, but IMHO they are decent eyepieces. Yes, the field of view is narrow, something around 36-38 degrees if my memory is serves me half decently. But they are reasonably sharp and they do not seem to have ghosts or other such problems.

With my RV-6 I normally use a set of Meade Circle T Orthos plus an similar vintage Meade Circle T MA-40. The scope does a nice job all the way around but the views in the MA-40 are quite amazing. Very sharp across the field of view.

I think I still have a Criterion eyepiece or two, Jon. My son, who's still using the RV6 I bought forty years ago may also have one or two. I'll bring mine and ask him to bring his to the star party near Palo Verde 04 & 05 November. If you make it, you can compare. I've always thought they were very passable.
