Nice sharp stars and plenty of H-alpha.  The OIII looks fairly subdued for some reason.

13 hours!  That's a long total exposure!  Is that your longest so far for one image?

Really nice data Roger. As Mark said. Possibly a bit more detail could be teased out and a bit of restraint in some parts of the processing could make this a really good picture.

Very nice Roger
Looks very clean and conrtasty; what happens if you leave a little more noise in the background?
