Joe,
I think the blue is real. Probably h-beta emission.
Also lots of blue stars in the central open cluster.
See my image below. BTW nice image!

Hi
  I finished processing my images of the Packman nebula and I was wondering
if anyone knows if this nebula has blue in its core area? The image link
below is a result of three images (60/90/75 minute exposures). Stacked in PW
and processed in PS.  Did I over process this image or is it real?
Thanks, Joe
