HOW TO FIND IT:
Be warned: this is one of the fainter objects in Messier's list. It is one of the most difficult to locate.
You will not see it with the viewfinder, sweep the area with your telescope's low power.
M76 is just one degree north and slightly west of Phi Persei. Once you find Phi, you'll want to scan just a little away from the star in the direction toward Cassiopeia.
WHAT TO LOOK FOR:
Look for a bar that is slightly brighter at the ends. William Herschel thought this was a double nebula, and so it has two numbers in the New General Catalogue. Some say this looks like a smaller version of Dumbbell Nebula, M27, and so is sometimes called the Little Dumbbell.
