Mu Cephei, or by its popular name Herschel's Garnet Star is hyper-giant red star with a radius of 1,000 times of our sun. It is one of the largest stars visible without optical aid, as its magnitude varies between 3.4 and 5.1. In the live fast die young crowd, it is nearing its end which at that size will be a supernova and possible black hole as a remnant.
Several other objects are visible in the field of view.
A planetary nebula PK103+00.2
Two open clusters.
