#Ideal F ratio for dobsonion

usually 8" dobs are f/6 with 1200mm of fl, most of them are pretty much the same in terms of quality so just look for the cheapest one
Thanks @leaden remnant
Thanks @glossy mirage
I'd go for an f5 dob @elder ruin
there is 1000mm
200/1000
and 150/750
f/5 superiority
Dob?
Thanks @signal bear
