View2 Posted May 18, 2016 Share Posted May 18, 2016 Torn between which 2" filter would best suit my scope for things like dumbell and cygnus loop. I have a moon filter coming already as the moon is blinding. The scope is a 127mm apochromatic ED triplet refractor, f/7.5 (fl=952mm). Although not f/10, it should still have high contrast(obviously I have not had it out yet). Have 2" Meade UWF EPS and some other 1-1/4 EPs). Am hesitating to get the UHC filter over an OIII. Hoping for some input here, and perhaps recommend brand. I know the baader ones are supposed to be high end, but have heard they are not much if any better than a celestron O3?
