Soul Nebula DSLR, 3hrs but no nebulosity?

In the StarTools forum look in the section User Notes, excellent guides in there by Guy and each has a link to the unofficial PDF.

Processing is quite addictive. I've overcooked the strength on the nebula but have better balance on the background.

Wow was that all in PI?  It certainly looks more defined now, but my takeaway from this is I really need a more sensitive (mono less noisy) camera and some Ha data for these nebs.  Oh and some more in-depth homework on Startools.  Thank you for taking the time to help me out on this.

I think we followed more or less the same workflow but obviously you've made much more intelligent use of the mask! Thank you again.

The original image is very good considering sub length, well done.
