Hi Rich I'm pretty hip to EP's and who does what. I guess I'm looking for some sleeper EP that is great on contrast, resolution, crisp and has good eye relief. I really don't like when I have to jam my eye onto the glass to get a view, so a little relief is good (also keeps oils off less flare from the oils). I don't wear glasses (except to read), I need an EP for when seeing is really steady and crisp and I'm working at high power and w/barlow. My 10mm TV Plossel is OK but it really has to be PERFECT seeeing for it to do good, I think it's my weakest performing EP. I'll replace it too, but 1st something to see Saturn and Jupiter with ( and I regret that I didn't buy the 5mm for Mars). I almost had a 5mm Radian on Astromart, I just couldn't get an e-mail thru and even called the fellow who sold it just minutes earlier. Oh well ............... We have clear but hazy sky here now. OK at the zenith but lower you can see some flare around bright objects. I'm spoiled here, good air and mostly warm thoug this AM wasat 54 and a bit nippy. :^) Aloha Rob
