I would like to know the technique you use to
colour differently the arms of the spiral and the bulge. I'd like to apply it to
my very modest picture of M31 I shot last July.
I've posted a new shot taken last weekend at
Mount Pinos of M31. This shot could probably use a little more work and
I might end up including more of the orginal (the posted one is cropped
significantly). The originals have very nice color. I didn't have
to do very explicit color correction on the image, just the basics.
