My boss bought a Nexstar 8" and asked me infos about it, I have the following questions:
#1. The 90d diagonal coming with the telescope, is it good enough to start with or it should be upgraded directly from the start?
#2. I want to propose a low power 1.25" eyepiece for it (along with a medium and higher power), my question is about the low power one. Telescope is 2032 mm of focal length, a 24mm would give 84x.
For me it's a bit too high, I would prefer a choice aound 40 ~ 50x. But I don't want vignetted views, it needs to be a low power eyepiece 100% compatible with a reducer, the telescope and it's visual back, the diagonal.
--> Which reducer, which eyepiece focal length and which eyepiece AFOV would be the best bet?
