Some nice colour there Duncan, and the IFN is starting to show especially in the larger version.

Well done.

Thanks Carole.

There is quite a lot of IFN in the data but bringing it out messes up the galaxies even more. I need to use Starnet to split the two really. Or learn how to apply masks (used to know but I haven't used them in ages).

Beautiful image!

Helmholtx IX is also showing nicely and (correctly) appears blue. I agree with Carol that the colour overall is excellent.

Oh - that is nice!
