The Helix Neblula - NGC7293 Orion 8" f/4 Astrograph

Uploaded 10/15/16

 One of the largest planetary nebula in the sky is the Helix Nebula. Located in Aquarius, it rides high on October evenings and presents a great target for wide field and longer focal length astrographs. It is moderately low in surface brightness however, and even 20 minutes is only starting to record some of its outer dim features. The main body is 15 arc minutes in size, half the size of the full Moon.
