NGC 752 is a bright open cluster in the constellation Andromeda, scattered NNE of 56 Andromedae.
An object that may have been NGC 752 was described by Giovanni Batista Hodierna before 1654. It was independently discovered by Caroline Herschel in 1783, and cataloged by her brother William in 1786.
NGC 752 is a very large (60'), loose collection of 60 to 70 stars of magnitude 8.96 and fainter, with a total magnitude of 5.7. A 6th magnitude star marks its eastern edge, and a close trio is visible south of center. The cluster is full of short chains, irregular clumps and a large number of double stars. NGC 752 is a fine sight at low power and is at its best in giant binoculars.
NGC 752 is 1,300 light years away from the Solar System. Its hottest stars are of spectral type A2, indicating a rather old age of 1.1 billion years.
