Thanks for chasing it up Mike. So those spots either side of the bright stars in the blue neb are real? Someone else's image is not conclusive as they may have though they were artifacts and deleted them using the healing brush. But they are perfectly round unlike the other patches of red.
I wonder if a Ha exposure of this area would clear it up. If I get my filter wheel sorted quickly enough I think I will image this on my CDK and see what comes up. Its worth adding a Ha layer as there is more there than I think most of us thought.
What's HH stand for?
Greg.

Greg and Slawomir, I found This APOD shot by University of North Carolina using a 32" scope at extreme altitude at Cerro Tololo. It's the "Answer in the Back of the Book". There are two faint but intensely red star-blobs towards ten o'clock from Yoda's head, and a few other smaller red splotches around Yoda's scone, which prove to be real, and are possibly HH related. In M&T's image, there are three red blobs more or less along the line of the horizontal diffraction spike from the top ultrabright star. These are artifact. (We notice they're not in Mike Sidonio's or Dylan's shots either). We'll seek them out and destroy them utterly in the next version. Destroy them, we will.
Best,
