Can anyone decifer the "circle" codes on my "astromart" Ortho's? I have a 4mm (Celestron) Circle-T, a 7mm (Celestron) Circle-V, a 25mm (no-name) Circle-A, even a 20mm (no-name) Circle-T Erfle! All of these eyepieces perform excellently, but I am trying to find thier manufacturer and year.
Thanks!

Circle-T is Kokusai Kohki, I think. See

http://www.kkohki.com/english/Kkohkiparts.html

though the logo may actually signify a subcontracting manufacturer. Circle-V is Vixen. Both companies sell a number of eyepieces. Never heard of Circle-A.

Note, it seems that Vixen orthos are likely to be Plossls rather than Abbes.
