Hi all
I have been experimenting with this procedure for a while which as you know is a technique whereby you seperate out the large scale detail from the small scale detail, treat it, then recombine in pixel math.
I thought M31 would be a good example to start on.
Here is the original SBIG STL image, which includes 6 hrs of Ha.
and
here is the reworked image (3Mb).
Let me know what you think.
cheers
Martin
