C/2007 N3 Lulin

The second image was auto-contrasted to make the comet more visible (click to embiggen and see annotations).

This is a 13 second video made from the two images.

There are lots of images ans video out there. This is the most astounding I've come across. You can briefly see the dust filaments coming off Lulin. The original is courtesy Space Weather dot com and Filipe Alves of Portugal.
