Description

Another planetary, this one shows distinct patterns in Ha, S and O so you can get really crazy with colour combinations!

O was very weak no matter the long subs so I couldn't really get fancy with its details and at the end I had to use convolution to smooth it out a bit.

Ha was great and S decent so I did significant deconvolution there (an algorithm I'm slowly getting the hang of in postprocessing that looks really promising once tweaked).

Finally I'm improving on mixing RGB stars using short 1x1 subs with narrowband data at 2x2 binning, managing to remove stars without damaging the delicate structures.

Enjoy!
