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.
Equipment:
-telescope MEADE LX85 8″ f/5 Newton.
-Baader MPCC coma corrector
-filter Meade IR-cut
-camera QHY5III178m (588 frames per 5 seconds).
Calibration and stacking with Fitswork, background flatten with Regim, noise reduction with PixInsight LE.
Scale 50%.
Location: Russia, Anapa, backyayd.
Galaxy M 81, single frame 5 seconds.

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