So, I'm considering picking up a scope come fall (my first in a few years), and one of the last bits of info I'm collecting is how well increasing aperature does in combating light pollution (assuming appropriate filters).
I've looked around on the net and haven't found anything that even guesses at how much extra a few mm of aperature will reveal given bad light pollution.
Where I live is about a 7ish on the Bortle Scale (link). Naked eye I can see to about 3.8, 3.9 on a good night. With just 50mm binoculars that increases to about 5.8.
I'm considering anything from a 90mm to a 125mm scope. But am I just throwing good money away after a certain point? I'm looking at a Maksutov, just because it's easier to pick up and drive to a much better site (Bortle of about 3 is within a 40 min drive, 5 is about 10min), but I'll be doing a good chunk of observing from my roof.
