NGC6543
 NGC6543
Cat's Eye Nebula

Planetary nebula (dying star). Magnitude 8.1. This nebula is very small, only 23x17 arcsec. For this shot  I used about twice the focal length as the other nebulas on this page, and further enlarged the image by 2X. Composite of 84 (out of 500) 10-second exposures. Full color. North is to the right.
