Description

Went light on deconvolution because it looks a bit weird with too much detail!

Chose not to linear-fit the Ha and OIII as the OIII is pretty strong naturally.

Combined into HOO, extracted luminance from that, removed & shrunk stars, deconvolved without stars, then recombined the stars into a final synthetic luminance frame for further processing.
