In late July, I managed to leave for the dark sky in the area of the village of Varenikovskaya. The sky there is really good at its zenith, but from the south there was a noticeable orange flare. I could not resist and again shot a number of hydrogen nebulae – M 16, M 17 and Barnard 312. With auto guide and shutter speeds of 2 minutes, there were practically no defective frames.
