Bright meteor before the Andromeda Galaxy!

Lights from ... a meteor crossing a galaxy

This is actually my luckiest moment I have ever lived in astronomy: a meteor crossing the Andromeda Galaxy !

I took this image at prime focus of a 200/800 mm newtonian telescope with a Canon 600 D camera.

This is a 30-second-single exposure.

More details about this rare event:

Since such a phenomenon does not regularly occur, I have written an article on my blog (obviously, I have made an english-dedicated version of my article) :
