Re: [APML] Cederblad 214, NGC 7822



Thanks Volker and Chris.
What I did differently with this one was to make a blend of the
HA data and red channel (using lighten) and then substitute this
for the red channel. In this way the stars are borrowed from the
red channel and the RGB is now strong enough to be matched
with the high contrast HA luminance. The problem on the previous
image I did (IC1396) was imperfect focus for the blue channel. I spent
more time on this image getting good focus so there are no blue halos.
