A couple of days ago, I went to work in Abrau-Durso, took with him a mini-astrograph.The main task was to shoot the nebulae in Scorpio, but I could not resist and decided to shoot my favorite nebulae in Sagittarius – M 8 and M 20. Local light pollution interfered noticeably, but closer to one in the morning some of the lanterns were turned off.The sky was noticeably better than Supsekh, but the filter Optolong L-Prois still useful and now it will be in the camera all the time.With the white balance did not arise.
