- Name: GM2-41 & LBN 248
- Type: Reflection and Emission Nebula
- Constellation: Cygnus
- Coordinates: 20h 32m 10s RA, 40° 18' 28" Declination (J2000)
- Notes: GM2-41 is the blue reflection nebula. LBN 248 is the brighter emission nebula just below and left of the blue reflection nebula. This is a very active star forming region with many Herbig-Haro (HH) objects and Ha emission stars. See here for some of these objects. Unfortunately my image is not deep enough to capture the HH objects.
I couldn't find another color image of these two targets. If you have one, I'd love to see it!
I first saw this object in a widefield shot I did of the region. You can see that image here. This object is on the far left edge of the wide field image.
