IC1396 is a vast round nebula at the north side of the Milky Way in autumn, has a diameter of about 3 degrees. There is a red star with fourth magnitude at the north edge of the nebula, you'll see the star being a curious red with scopes. The star, mu Cephei is a semiregular supergiant that also varies roughly from 4.5 to 3.5 with a very long period of 730 days, and prompting William Herschel to call it the Garnet Star.
