Re: Best Eyepieces For $100 or Less

To All,
Thanks for trying to answer my vague question. Should've known better to not list my equipment. Right now, I'm very diverse in that my main scope is an 8" SCT (f10) and my second scope is an ST80 achro (f5). Perhaps no eyepiece is going to be perfect for both simultaneously. And yes, I do wear glasses when I observe. I'm just beginning to really study eyepieces in depth, so really all of your replies have taught me a lot already even if the info doesn't necessarily apply to my equipment and situation.
Right now I have a very meager selection of eyepieces: 40mm Sirius plossl, 25mm Celestron SMA Wide, and a 7.5mm Sirius plossl. I also have an ancient set of Criterion eyepieces: 18mm, 12.7mm, and 7mm. While the Sirius plossls perform ok, the peephole in the 7.5 is bothersome. The Celestron isn't bad and easy to look into, but does have a good deal of curvature around the edge. The Criterions actually work pretty good in the SCT, but have a very narrow AFOV and, of course, small eye lenses. I need to fill in the gaps on focal lengths (not considering the Criterions) and would like to retain as much eye relief and AFOV as is practical without sacrificing optical quality (especially when it comes to curvature around the edge). I can't afford an Ethos and many high-priced Televues and the like.
Now, by golly, if I had only said all that at the beginning, this thread would be a bit more coherent perhaps. Sorry. Still learning here.
