Description

Another product of my astro-camping weekend: M76, the Little Dumbbell Nebula!

After having some weird guiding issues on my Paramount MyT, I managed to get at least some data on this target, which turned out pretty decently thanks to the low light pollution! This is the first time I've imaged this little guy.

M76 is a planetary nebula in the constellation Perseus, about 2,500 lightyears away. Planetary nebulae are the deaths of main-sequence stars (like our Sun) as they are ejecting the majority of their gas and turning into white dwarfs. It is approximately 1.23 lightyears across -- nearly 2,000 times the radius of Pluto's orbit! It's expanding at a rate of 42 km/s (nearly 94,000 mph!)
