According to the light pollution map, my location has light pollution between the white and pink zones. The area is Pokrovskoye village, Istrinsky district.
I checked the map, and it should be Bortle 5, which is yellow. That's how I look at it. There's a map that shows the Bortle scale specifically, and then I convert it to a color. I would send you screenshots, but unfortunately, you can't add screenshots in comments here. It's very hard to navigate by color alone, so I use a map that shows the actual scale value. Unfortunately, I only know of a 2015 map like that. https://www.lightpollutionmap.info/#zoom=10.73&lat=55.8703&lon=36.8954&layers=B0FFFFFFFTFFFFFFFFFFF
How do you manage to capture such galaxies in a white zone? How do you achieve 300-second exposures without overexposing the background? And the diffraction spikes from the secondary mirror supports look as if they were added separately?
