I have a CPC 1100 Edge and I am presently making a decision on an eyepiece that would fill the mid-range of magnifications for my scope. Right now, I mostly use a Luminos 23mm to fit the bill. That and my 12mm Delos see the most time. Right now, I am a bit split between two eyepieces: ES 17mm 92 and APM 20mm 100, preferring the latter at the moment, mostly because of it's ideal focal length for the scope. (Note: I am not considering Ethos yet, since I have never owned a 100 degree eyepiece and want to make sure I really like them.)
My question to you all: which would you get in my situation?
There are obviously pros and cons of both. I like the magnification, exit pupil, and weight of the APM. I like the Delos-on-steroids feel of the ES 17mm. I like that you can easily take most of the FOV in, unlike the APM. However, I find myself preferring 20-23mm over 17mm in my scope. It seems like the APM 20mm will have the best view for most DSO objects I am looking at. Tell me if I'm wrong. I know some that really like the 17mm in this scope. Another consideration is that I suspect that, if I buy the ES 17mm, I will also need to buy eventually a 22-23mm for that range (The Luminos is not my favorite by any means). The 20mm APM would be a nice in between 17mm and 23mm, making those less necessary and thus perhaps saving an extra eyepiece to lug around. (On the other hand, the jump from 20mm to 12-13mm is a big one.) These are just my thoughts right now....
Anyway, I can go either way. So I thought I would ask advice to the forum. Any advice is welcome, and especially if you have this scope or a related one.
EDIT: It might be helpful to add that I use my telescope in a very light polluted area of Phoenix (zone 9) about 70 percent of the time and a dark site (zone 2) the rest of the time, about once a month, as the weather and wife permits.
