We can't all live in the desert or on a mountaintop or in a closed community with strict light pollution laws. Many of us live in urban settings and do a lot of our observations and astrophotography in our backyards.I live in a large city and my limiting visual magnitude is about 3.5-4.5 depending on conditions. My dslr registers red murky, mercury vapor colored sky after a very short time, dependant on focal length.When I shoot images I must use filters to block certain wavelengths of light, causing a dramatic decrease in signal and requiring a dramatic increase is integration time to get an equivalent image as what my counterparts in a more rural, less light polluted area get.This is a place to share our pitfalls, detriments, workarounds, solutions and remedies to astrophotography issues unique to our urban environment.
