Fireworks Galaxy (HaLRGB)

The Fireworks Galaxy, NGC 6949, gets its name because ten supernovae have been observed there in the last 100 years. That is a rate far in excess of what most galaxies see. The average is about one per century per galaxy. We have not observed one in our own galaxy in around 400 years.

The galaxy is about 25 million light years away in the constellation Cepheus. It’s about half the size of our own Milky Way.

This is a bit over 26 hours of data. For all the technical details see the astrobin.
