Let's see, to double the signal to noise ratio you'd need another 124
hours. Least I'd think the square law would apply here.

Now the connection between the main nebula and the red blob on the left
is starting to show. I was wondering if they were even related.
Appears they are.

You'll end up in the Guinness book of records if you don't stop now ;-)
I wonder if there is a practical limit to "useful" exposure times. Adding
some more hours certainly improved the image, but would e.g. 80 hours be
noticeably better than 60 hours? Maybe you will show us ;-)

Rick thinks you need another 124 hours! Or it may be time to order that
36-inch scope and liquid nitrogen cooled back-lit camera!

Of course the results you have are spectacular and really tell the story of
this nebula.
