This is super cool. I studied comets for a while when I was in academia, and my favorite was one called Humason [0]. There are other great photos of it, some in google images, though the ones I had in the research lab in a a few books about comets were even more surprising. It had a very odd tail appearance because the comet tail is primarily created by an interaction with the solar wind / magnetic field, and at distances far from the Sun, that field is much weaker, so the tail becomes less straight, and this effect is even more pronounced when the comet is very large, as smaller comets just don't have an easy to detect visible tail from such great distances from Earth.

Humason is less than half the size of this comet and is considered abnormally large.
