I live in Murrieta Ca and the light pollution maps I can find are from 2015 indicating that I am in Bortle 5 skies. We are surrounded by new developments and I have 2 yellow street lights less than 100 yards from my backyard. So it seems the light pollution is worse than Bortle 5.
I can barely see any of the Milkyway at the zenith....so I think it's actually ~ Bortle 7
My questions is how long should I image to get the best SN ratio in stacked images?
