Firework

Informations

The firework galaxy (NGC 6946) is a face-on intermediate spiral galaxy with a small bright nucleus, with open spiral arms in the constellation Cepheus. It is about 22.5 million light-years away, making it a member of the Local Group of galaxies. It was discovered by William Herschel on September 9, 1798. It has an apparent visual magnitude of 9.6, therefore it is visible with binoculars.

It is called the firework galaxy because it has had ten supernovae observed in it since 1917, making it one of the most prolific in this respect. The most recent supernova was SN 2017eaw.

He managed to get way more data and a better processing than me, I love the purple color he got on the galaxy. I don’t understand why the galaxy is still blurry, it might be a matter of integration time, maybe the more data I will get the less blurry it will look but I have no idea yet.
