Those were my ES 100º….maybe a bit too cheap…who cares... I don't. They were really terrific in my f8 6" and f9 100ED refractors, but not so good in my f12 6" refractor, don't know why. I have had them in my f4.8 Newt and didn't like them one bit…talk about coma city. So if you get the 100's you are going to have to get a coma corrector too, at least I had too, and that is a lot of tubes hanging out the focuser…a lot. Give me 68º eyepieces any day. Not so bad in the Newt without the CC perfect with the CC (coma corrector) and perfect in any of my refractors 70mm f7, 90mm f11, 100mm f9, 150mm f12, and not forgetting 50mm f12
What a little cutie it is.
If you haven't done so check out the Cloudy Nights eyepiece section…it's a mine of information…..
