A buddy of mine (actually a person and not that random blonde I dated from Canada that never visited because of visa issues), he isn’t on here but asked me this question and my answer is definitely not as educated as a lot of you will provide, so here it is.
You just got an 8” SCT. You have committed $1500 to go berserker on eyepieces. Your goal is planetary viewing....lunar viewing and you want to go DSO hunting. You live in a Bortle 7 area but hit a Bortle 4 once a month. Your seeing on most nights is Average.
Don’t pick apart the specifics. What do you get? Do you get a 31mm TV or is that money that can be spent in better areas? How high powered do you go? I’ve avoided <10mm because the times I’ve used them have been underwhelming.
What do you get?
Like I said, my answer is based on hype, reviews and 6 months of experience. Ergo, I don’t think I’m the best equipped to spend here. That said, I would get the 31mm Nagler because, what I’ve read and seen has been pretty solid. I also like the ES pieces. I have an ES 40 62 degree (or 68, I forget) and I love it. I also have the Baader Zoom which is nice and flexible.
