Description

The Rosette Nebula, in my own HO palette.

I have had quite a few comments on my palette, on this and other images. Here is what I use:

L = (H + O) / 2

R = 1.5 * H - O

G = 0.4 * H + 0.325 * O

B = O

You have to be a little careful on the red channel, with the negative Oiii term, not to clip the darks. My Oiii is always weaker than the Ha, so this is seldom a problem.

I find this palette gives a warm, natural feel to what is really a false-colour image.
