Thanks Gary,

I do like the nice reds I get from the SBIG, a far cry from my unmodded 40D.

As you go through your processing routine, keep a close eye on the histogram. Don't raise the black point too much early on in the routine. Its always good to finish with some "white space" before flattening the image. Then close with linear stretch (levels) bringing the background in check. Looking forward to seeing more. Well done.
Thanks Jase,

I guess I failed at the final hurdle . I was going OK until the end and then raised the black point, I usually do this to darken the background but maybe should try something else.

This was a different way of processing as well. I produced two images from the data. One pushed not so far so i didnt blow out the center of the neb and then one where i pushed the outer nebulosity. Then i layer merged them. I need to read a bit more about this technique I think.
