NGC-7293 The 'Helix'

NGC-7293 The 'Helix' Nebula in Aquarius. Size 15'x12' with a magnitude listed as 6.5, but because of very low surface brightness is difficult to be seen with a telescope of less than 6" and the aid of a filter. This object if it were bright enough, would have an apparent size half that of the moon. Imaged with a ST-6 camera, Tri-colour RGB of 9-21-24 minutes.
