A little advice please.
I thought I had it all figured out but ......... now that I see them up close and in-person and start comparing the deals, I am having trouble figuring out which is better for my situation?
Situation: 60% land viewing of ships 1-5 miles away 40% moon/planets (ideally see the red spot on Jupiter and some detail of Saturn rings).
Right now I'm trying to decide between:
127mm or 5" Mak with a 1500mm focal length
150mm or 6" short tube Refractor with 750mm focal length
120mm or 4.7" long tube Refractor with a 1000mm focal length
Any comments or advice?
