Planetary Nebula in Puppis

Uploaded 2/12/02

Located just north of the center of the bright star cluster M46, this gem shines at 10.1 magnitude amongst a sea of cluster stars. It is large for a planetary, at 64 arcseconds and reveals a wealth of color details from the ionized gasses within. No visible galaxies lay in this field, being too close to the galactic equator. The central star is barely seen here. it is a very faint blue object, just to the lower left of the brightest star within the ring. This 18th magnitude object is nearly swamped by the nebular light.

Processing: Calibration, RL deconvolution, final brightness adjust.
