VV Cephei is another one of the red super giant stars located in our galaxy. It is also an eclipsing binary star system with a much smaller companion star that is close enough to draw off some of outer layers of the primary star. The orbital period of the pair is around 20 years. The interaction of the secondary star pulling off the outer layers makes for some interesting spectroscopic variations as the stars eclipse one another.

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.
