Comet ISOn by Damien Peach

[Knight of Clear Skies]

Out of curiosity I dropped the image into Astrometry.net to see where it was and I was surprised to several others have got close to Damien's pic in the similar images. here is one http://nova.astrometry.net/user_images/133847#annotated

Thanks for the link. APOD has a gallery of the year's comets here, some of the recent ones at the bottom are showing similar levels of detail in the tail after the recent increase in activity. I think the patterns are caused by localised jets as it rotates, making a spiral.

Utterly awesome picture!

Just used for work on comets with my astroclub at school   - kids were inspired by this & Melsky's comet and fireball gif.

Here's some artwork they produced:
