Spiral galaxy M 81, March 31, 2019.

In March, I managed to photograph a bright galaxy in Ursa Major – M 81. This is a classic spiral galaxy, easily visible even with binoculars. The company “Meade Russia” kindly provided me for testing the MEADE LX85 8 ″ f / 5 telescope Newtonian reflector. The shooting was done with short exposures (5 seconds). The level of light pollution has become so large that the details of galaxies are simply drowning in the flare. Therefore, all hope was to stacking frames and stretch the spiral arms through processing.

      На одиночном кадре хорошо вижу “гало” галактики пока двигаю страницу скроллом. Как только останавливаю и смотрю в центр кадра – его площадь заметно уменьшается.
