Hi All,
This ones a bit of a blast from the past.
I stumbled across a new way of processing comet images to get rid of the rainbow stars I usually end up with because I image with a monochrome camera. (

I hunted around and found this set of data from about a year ago.
I like the result. With a little practice I think it's a winner.
Before and after shots below.
Cheers
Stuart
