My previous scope (6+ years ago) was an 8" dob. I liked the combination of FOV and magnification using Baader Hyperion and a 2.5x Powermate. I had a range of 56x --> 325x. I assume most of my viewing was probably in the 100-200x-ish range, occasionally down the the low end and when capable, I would occasionally push the high end. I got a really nice view of Mars at 325x once that was great.
I've now got an older 8" Nexstar Evolution. The guy that I got it from included a couple of random EP and a 2x Barlow.
I think I'm looking for a range more like I had on my old Dob. I had thought "I'll get a focal reducer corrector and then similar EP to what I had before," but then I realized that I could skip the f6.3 reducer/corrector and just get EP that gave me something similar. Granted, to get similar FOV, I'm pretty sure I'm going to have to spend more, getting EP that have AFOV in the 76º-82º range instead of the 68º hyperions.
So, does that seem like a reasonable course of action?
I was thinking, something in the 24-31mm range would give me low power views, then maybe something in the 21-16mm range (AFOV to vary depending upon the option and availability). Then maybe something in the 14-11mm range and again 10-8.5mm. Then I could try the barlow for the rare times when I wanted to try pushing into the 250-350x range.
And for those ranges, if for instance, I went with a 16mm instead of 17 or 17.5, spend a bit more and get something with a wider AFOV to try to keep the views similar. But if I went with 21mm instead of 16mm, then I could go with something like the hyperion at 68º.
Please point out flaws in my thinking or recommendations.
