Quote:The 8mm Hyperion with the 14mm Fine Tuning Ring (around $15) will make that eyepiece a 6mm Hyperion. I would suggest doing that as a cheap, easy, and FUN way to get to 6mm.

Fact: I like reflectors and big ones. All the refractors I own are either finderscopes, binoculars, or riflescopes.

Quote:I found the Radian more comfortable (better eye relief, slightly wider FOV) than the TMB, but otherwise they were indistinguishable.

Quote:hiThanks and I looked for a long while for Radian. I'll keep looking. It doesn't even seem they make the 6mm new any more. maybe in the mean time I will get the fine tuning ring that Bill suggests. How does that work exactly? If anyone has a lead on a Radian 6mm let me know. I'll also keep an eye out for a cheap used BC or BG ortho out of curiosity. I like the idea of the Ring because I like the Hyperion a lot. I never see people talk about them but to me they seem like really good EP's.ThanksPaul

Quote:A Baader Classic (or even the amazing 6mm TAL Plossl, which is also cheaper) is, IMHO, the best budget-minded pick.
Quote:Between my 2 samples it is almost a draw. The BCO has a tiny advantage in contrast, transmission and scatter control, a somewhat larger field of view, and is noticeably more comfortable.On the other hand the TAL has a more uniform performance across its entire field (I judge the TAL being the real "orthoscopic" between the 2), and I like very much that feature on Moon and Sun.
Quote:The fine tuning rings are a nice options, but personally I do not like assemble/disassemble my eyepieces in the field.
