Fireworks Galaxy NGC 6946

The Fireworks Galaxy (NGC 6946)

A spectacular view of a dramatic spiral galaxy seen through a mass of stars from our own Milky Way Galaxy. It took the light from this galaxy 22 million years to get here. I'm glad it was a clear night.

 

It gets its name, Fireworks galaxy because of the number of Supernova explosions that have been reported in the galaxy. In the last century alone, at least 10 supernovae have been detected in the galaxy. N.A.S.A.

It is also known as a Starburst Galaxy galaxy due to the number of new stars being created.

Tracking but no guiding. I haven't been able to get the guide camera in focus either with OAG or separate guidescope yet so I restricted my captured to 30 seconds each to keep the stars round.
