Thanks Steve. Appreciate that. It took me nearly two months to finish this.

Albert;
What a terrific image. Lots of detail and color. It is truly amazing what a
modern camera and software will do.

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 :)
