Hi Karl
Your image and the processing are very good.
I had a look at NGC6559 for the first time a few nights ago.
It's a very interesting part of the sky, lots of Ha.
Our results are quite different and I think it all comes down to the quality
and amount of data.
You have about 5 hrs, I have about 15 and there is really no substitute for lots of good data.
Re where you should post: It doesn't really matter, wherever you feel comfortable.
Well done
