NGC6543

Planetary Nebula in Draco

Uploaded 6/30/02

A planetary nebula of most unusual coloration, this very high surface brightness object is 8.8 magnitude and 20 arcseconds (yes arcseconds) in size. The very blue central star is a beacon at 11.1 magnitude. Look closely at the unusual structure seen here. Polar "jets" of material, red here are seen at about 12:30 and 6:30. Light colored internal arcs are around the central star, and pink and yellow colored spots are on the vertexes of the long axis of the object. Yes thats a galaxy off to the right, blue with a hint of a single pink HII region, this is16th magnitude IC4677. This object is shot with a barlow lens to yield f/9, similar in focal length to many of the R/C optical systems many are doing CCD work with today. Faint diffraction spikes can be seen extending from such a brilliant object in this image as well. My diagonal vanes are rotated 45 degrees from most newtonians due to a square tube.

Processing: Photoshop curves and luminance layering were used to preserve the extreme range of brightness and deep coloration of this object.
