Really looks nice Albert. The HA really brought out the hydrogen areas.

Last night, at my home in Phoenix, I added 4 hours of 900 second Ha
exposures to this image I took remotely in New Mexico over the last 6 weeks.
I now have a total of 16 hours on this version. If you look carefully you
can see some of the hydrogen, particularly on the upper bands. Stars are
still color and this final version is now an HaLRGB. The full size JPEG is
17.7 megabytes and looks amazing on my IMAC 24 inch screen. The tiff I used
is 221 megabytes :)
