Need to stop extreme shooting from the city balcony without light pollution filters. What to do if there's no opportunity to go out of town during the week, and I also want to sleep at night? ...
Shot in a red zone of light pollution. Full calibration: dark, flat, bias.
Had to resort to extreme measures during processing to even out the background. Will reshoot the object under good skies outside the city.
