Hi Marc,

That is Ha and O111. Ha is red, O111 is blue and green is an average of Ha+O111/2 (using pixel maths).

Then RGB weightings were something like red (2) green (.7) blue (.8).
These weightings I tended to modify to suit the image.

I wasn't really happy with it so I didn't publish it. The Eagle Neb escapes me so far. Perhaps another attempt at it this weekend.

Cheers,

Greg.
