Hartley 2

Here is a picture of the Comet Hartley 2 from 10th October (not very current). Perhaps it should be renamed Harley 2, because of its ability to move during the time it takes for its picture to be taken. The green colour comes mostly from the molecule C2. Hmm... I wonder what that smells like. I tried to process to give the most coma and tail, but probably have included some optical artefacts due to not using a flat field correction to the image.
