M27 Dumbbell.jpg - M27 NGC6853 Dumbbell Nebula Planetary Nebula with White Dwarf distance: 1,360 ly actual size: 1.4 ly apparent size: 8'x5.5' image size 20'x20' FLI PL-16803 camera 12.5" Planewave scope @ 2500mm (f/8) AP900 mount 8 hour total exposure LRGB 200:80:100:100 subs 10:10:10:10 binned 1:2:2:2 (0.73" per pixel unbinned) MMOAG with ST402-ME camera guiding The Dumbbell Nebula is considered by many to be the finest planetary nebula in the sky. It was also the first planetary nebula discovered (by Charles Messier in 1764). It is easily visible with binoculars. It is believed to be no more than 9,800 years old. The central star, a white dwarf, is about 5% of the size of the Sun with a mass of about 55% of the Sun, making it the largest known white dwarf. It has an angular size of about 8 arc minutes. The Helix Nebula is the only planetary nebula appearing larger.
