M33 in "Triangulum"

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.
