Cometary Globules are not image too frequently although many could be. Many are very small or very faint, but some are of good size/surface brightness for even wide field imaging. I have imaged 18 of them, which, I believe, is about as many as any amateur has done. Here is another, CG 11:
To see others that I have imaged go to my "Catalogs" page and look in the far right column entitled "Other". Then scroll down and click on the respective link.
You have supplied us with a real "running cometary" on these dusty fields Tom and have certainly built up an impressive catttledog of these piles of comsic dirt.
I should add - I am collecting data on the dark tower in Scorpius at the moent - a fairly easy CG - I understand how difficult it it is to process this stuff just above the background levels and not overstretch . Im starting to have some luck with Pixinsight with the masking techniques but not enough to publish yet.
