Tagged: NGC7293 - Adam Lundie - Eatons Hill Observatory

I've already done the Helix Nebula in natural colour, so I've imaged it again in narrowband. Lots of H-alpha and Oxygen-III, but barely any Sulfur-II.

The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula located in the constellation Aquarius, 695 light years away.

Often I like to see how an image is processed from start to finished. Presented in this animation are the main processing steps in sequence from my image of the Helix Nebula
