Thanks,

great start Duncan
yep coma corrector is the way to go. as jjjnettie has mentioned lens correction can help out post production but can be a little tricky when the coma isn't even (notice the bottom left of your pic hasn't got much compared to the top right). a lot of people crop out the edges to avoid the worst sections.
already making some quick progress
some more data and you'll have something to hang on the wall.
cheers
