The weather has been pretty poor recently so have taken the opportunity to try and get to grips with blending HA data in PI.
NGC7293 Helix in HARGB
6 hours of RGB data were blended with the 9 hours of Ha that I posted recently.
Still working through star colour and star masks, but I did enjoy learning how curves can be used with such effect on the final processed image
No stars were deconvoluted during the processing of this image, in fact no sharpening was used at all. Maybe it needs it but if you stand back a bit its not so bad.
I am though intrigued as to why my iPad eats Ha when viewing through astrobin. Anyone else noticed this? It clips the data quite hard. I work in 32bit FITS files with embedded ICC and according to PI, the colour profile is sRGB.
Thanks for looking
