(1) Siebert 7mm -- "fully coated, 4-element, 65 deg. FOV, 6mm eye relief". Costs $49 + s&h. I'll sell for $44, includes shipping Con.US.
This EP is very good -- sharp and contrasty, and with wide FOV. It doesn't have threads for filters -- you just kind of "twist and push" to get a filter in, and it holds securely. Being an eye-glass wearer even when observing, I find that the short eye-relief is not comfortable for me. Were it not for this -- and ONLY this-- drawback, I would have hung on to this li'l cutie (...homely-looking cutie.) It's a no-nonsense, very good performer (on my 80mm refractor.)
I will take money order, or discuss with you other ways of transaction.
P.S. -- I have 12.5mm Sieberts (2 of them) for sale, too, under another entry.
