M76 Little Dumbell

M76 Little Dumbell

Object: M76
Constellation: Perseus
Distance: Undetermined, possibly around 3,000 to 8,200 light years

Magnitude: ~12.2
Commentary: M76 is very faint in the eyepiece, but exhibits well in digital astrophotography. Somewhat resembling M27, the Dumbell Nebula, the name Little Dumbell has stuck as its primary moniker. The gas and dust surrounding a central star, which is responsible for the outflows, was probably ejected by that star around 10-12 thousand years ago when in its red giant phase.
