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.
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.

AT2019ABN, 25\03\2019
Подбирал объекты для съемки и понял, что этой осенью еще не снимал галактику М31. Точнее, снимал, но результатом был не очень доволен – попробовал подружить Samyang 135\2.0 и камеру ZWO 290 MC без IR-cut фильтра. Результат получился столь мыльный и ужасный, что даже не стал выкладывать. Вчера снова отснял Туманность Андромеды, но уже на монохромную камеру с IR-cut фильтром. Даже камеру ровно выставил с первого раза, без перекоса 
. Сама галактика ночью практически в зените, однако мощный прожектор в центре города и градиент засветки неприятно напоминают о себе.
