Description

The Helix Nebula is a planetary nebula located approximately 650 light years away. I was going to capture in the Hubble palette but my Sulfur (SII) data was unusable so I processed as an HOO (Ha and OIII) image. One of my goals was to see if I could resolve the knots of nebulosity called cometary knots.
