NGC 6822 Barnard's Galaxy
Photo description / processing
I have wanted to photograph this galaxy for a very long time. But in our latitudes, it is very low, and the atmospheric quality and light pollution do not allow it to be photographed properly... Namibia, with its wonderfully transparent sky and absence of light pollution, gave such an opportunity!
I photographed it over several nights from October 14 to 25. Even in Namibia, it sets quickly now. And there is a peculiarity there - in the first hours after the onset of astronomical twilight, the atmosphere is very turbulent due to sharp temperature changes - 30 degrees during the day, dropping to 10 at night, the desert...
To the left of the galaxy, a faint dust lane is visible, and dust can also be seen on the right.
