This is another discovery by Charles Messier in 1773. About 80 years later it was established that it was a spiral.

The blob on the left is in fact another galaxy - NGC5195 that is interacting gravitationally with its neighbour. Stars don't crash into eachother, but galaxies do!

This is a 7 hour total exposure, captured over three nights. 5 minute subs. Location central Lyon, France.

A fellow SGL member did a far better job editing this TIFF than what I show here.
