Emission Nebula in Perseus

Uploaded 1/16/01

This intriguing object in Perseus has no common name, but is plotted on most atlases as a small box nebula. The field here is 10 arcmins wide, and reveals the emission object to be cut by both thick and thin dark lanes of obscuring dust. The pair of red stars just to the upper left of the nebula were very strong in the red filtered shot, and appear to be genuinely ruddy probably due to obscuration by dust in the nebula. The seeing was the best I've ever seen in Payson, the stars simply burned and did not twinkle at all.
