Two comparative images of the Messier 101 galaxy with and without a supernova

Summary[edit]

Description
Українська: Знімки отримано 18 березня 2023 року та 21 травня 2023 року. Перший південніше міста Бережани в Тернопільській області, а другий в самому місті.

Телескоп системи Ньютона Sky Watcher D=254mm, F=1200mm, коректор коми Baader Planetarium Mark III. Екваторіальне монтування: SW NEQ-6. Камера Nikon D7200, ISO 5000, exp=30s на кожен кадр. В першому випадку таких кадрів було складено 59, в другому - 151. Апаратна база в обох випадках була повністю однаковою. А от умови зйомки суттєво різними як географічно, що позначилося на різниці в засвітці неба, так і кліматично, коли березнева ніч була трохи морозною, а травнева явно теплою, що мало чималий вплив на теплові шуми матриці.

English: The pictures were taken on March 18, 2023 and May 21, 2023. The first is south of the city of Berezhany in the Ternopil region, and the second is in the city itself.

Sky Watcher Newton system telescope D=254mm, F=1200mm, Baader Planetarium Mark III coma corrector. Equatorial mounting: SW NEQ-6. Camera Nikon D7200, ISO 5000, exp=30s for each frame. In the first case, 59 such personnel were made, in the second - 151. The hardware base in both cases was completely the same. But the shooting conditions are significantly different both geographically, which affected the difference in the lighting of the sky, and climatically, when the March night was a little frosty, and the May night was clearly warm, which had a considerable effect on the thermal noise of the matrix.
