Nebula image is NGC 1977 and M 42. Pentax K100D DSLR,
Stellarvue Nighthawk 80-f6, 2 min * 56 exp. I had my old "refractor
blue bloat" around bright stars. I cheated and fixed most blue circles, but could not fix the stars inside the Running Man Nebula. I'm just happy to see the Running Man, blue nebulas are near
impossible with the SBIG camera in my location.
