While waiting for my main target to enter the visibility zone, I decided to spend an hour photographing a galaxy. I was curious how it would turn out with one hour of imaging in a green light pollution zone. A single one-hour session is much inferior to one hour of integration of the same galaxy in the city in an orange light pollution zone.
