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.

Sir Isaac Newton should have said, "If I have seen further than others it is by inventing my own telescope".

Thanks everyone. As you can surmise, there has been a few clear nights. :D
