Planetary Nebula in Cygnus

Uploaded 9/9/2001

During the full moon, while film astrophotographers are sleeping, the CCD astrophotographer can still take detailed color images as seen here. The moon was one day past full, and blazing in the eastern sky, washing out the milkyway to invisibility. This object, is one of the largest planetaries in Cygnus at 61 arcsecnds, and is located about midway between Deneb and Lacerta. The planetary is fairly bright at mag 11.3, and shows hints of blue and green in the central regions. The very faint 19.1 mag central star is shown faintly here.
