Description
The Helix Nebula (NGC7293) is a planetary nebula in Aquarius lying at a distance of about 700 light-years. Also known as The Eye of God I like to call it The Eye of Sauron! This Nebula have strong emission in both Ha and OIII. I needed a total of 10 hours of Ha and OIII data to process this image. Many of the cometary knots are clearly visible in this image.
