| Notes | The Helix Nebula is one of the closest of all planetary nebulae and with an apparent diameter of nearly half of the full moon is also one of the largest in apparent size. In fact, I feel that this is really the largest deep sky object that I can confortably image with the C11 and 6.3 focal reducer. |
