NGC 7293 - The Helix Nebula
|
||||||||||||
|
NGC 7293 - The Helix nebula is one of the closest planetary nebula to our Solar system, about 300 light years distant. It is located in the constellation Aquarius, and is the largest planetary in apparent size (it did not fit in my FOV at f/3.3). It subtends 12' x 16', or about 1/2 the apparent width of the moon. However, it has a very low surface brightness making it a tough target for visual and even difficult to image.
