Just my opinion, It really depends on what you want to look at that is
deep sky. I very rarely (that I can remember) using 200x on DSO's unless
maybe a faint small globs. Using a 10mm @ 120x in my scope singular
objects (but not always the case) using 20mm @ 60x for larger nebula
and galaxy clusters. 30mm @ 40x for larger objects again but even then
it can be hard and or some dont fit into the FOV. 200x is getting rather
high but not out of the question for DSO but seeing can come into play.
I mostly use that sort of power (200x plus) on planets and such. What
sort of scope are you using?
