Thanks to the guys at iTelescope again for access to this high quality data. Telescope used was a PlaneWave Instruments CDK 20″ f/6.8 with a focal length of 3411mm. The camera used was an FLI ML16200 all mounted on a PlaneWave Instruments L-500 Mount.

10 subs each of red, green and blue, each at 300 seconds given a total data accumulation of 150 minutes. Processed in Pixinsight and PhotoShop.

The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.

Thanks for looking.
