SIMBAD literature search shows several papers:

Bibliographic references

This one has:

  • Known IRAS source associated with it.
  • Known sample of YSOs?... need to read the literature a bit more.
  • There is a lot of optical emission, which is likely from gas. Is this an HII region?
  • But, it looks cool.

The image below is constructed using: blue = DPOSS2 (blue) green = 2MASS J red = 2MASS Ks
