Map showing the location of NGC 752

NGC 752 (also known as Caldwell 28) is an open cluster in the constellation Andromeda. The cluster was discovered by Caroline Herschel in 1783 and cataloged by her brother William Herschel in 1786, although an object that may have been NGC 752 was described by Giovanni Batista Hodierna before 1654.[2]

The large cluster lies 1,300 light-years away from the Earth[2] and is easily seen through binoculars, although it may approach naked eye visibility under good observing conditions. A telescope reveals about 60 stars no brighter than 9th magnitude within NGC 752.[3][4]
