Hi, Rod. Thanx for that report. Were you guys using a ParaCorr? (at lower mags). I find your observations encouraging, because I'm building that 36-inch F3.75... and was just a bit worried, regarding whether that is getting too fast. Which eyepieces handled the F3.3(3.8) gracefully? I have Naglers and some Ethos (which are too much field for my recessed eyes). 2500X ?! Lord Ross says, "Yep." Tom
I'm sure the owner was using a paracorr 2 which is the latest model designed for the fast f ratios now being deployed these days. You need that model if you're going that fast. I can't recall specifically which eyepieces he was using but I'm pretty sure they were Televue products, mostly likely naglers and ethos models and probably the latter.
