I took this series of 6 images over the last new moon and have been wrestling with the processing and mosaicing ever since. Each frame has only got about 15 minutes through each filter. I tried to make the HDR more tasteful, but decided, to hell with it, and went for structural definition around the fish's mouth and trapezium.
Maybe next year I'll go a bit deeper and add some Ha to the luminance.
Astrobin high resolution
here:
Mosaic done using PI's mosaic tool and used a combination of HDRmultiscale and the localhistogramequalisation tool to disrespect the light in the core.
Each of the 4 channels per panel were also an HDR combination of 60s and 10s subframe integrations.
cheers,
Andrew.
