The material was shot by me in July and August 2016. Unfortunately, at my latitude, at this time, the nights are still quite bright. The previous processing option did not suit me. The object turned out to be quite complex and the quality of my sky reduced the value of a large accumulation of shooting. Time passed and I was looking for image options that would suit me. Here is the fruit of my torment.
