Equipment:
-Samyang 135mm f/2 ED UMC Canon EF lens
-Canon 550Da camera
-Sky-Watcher AZ-GTi mount (EQ mode)..
Calibration and stacking of 50 frames of 30 seconds in DeepSkyStacker, ISO 1600.
Location: village Krepostnaya, Krasnodar Territory, Russia.

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.

For comparison a single frame without processing:
Galaxy M 81, single frame 5 seconds.

Galaxy M 81, single frame 5 seconds.

In the galaxy M51 “Whirlpool” appeared an interesting star – AT2019ABN. This is a possible supernova, or “imposter”. The star has already dropped the outer part of the shell, but the nuclear reactions are still burning. It is possible that in a few tens of days its magnitude will increase by 2-4. At the moment, its magnitude in the R-filter is about 16.5m. In principle, it is available for shooting from an aperture of 100 mm or more. I recommend astrophotographers to take pictures of this star – the data may have scientific value, and there is a great chance to photograph a supernova explosion.
