The constellation Cepheus as it may be seen by the naked eye. Alderamin, also known as Alpha Cephei, is the brightest star in the constellation, with an apparent magnitude of 2.51. [5] Gamma Cephei, also known as Errai, is the second-brightest star in the constellation, with an apparent magnitude of 3.21. [6]
Gyulbudaghian's Nebula (gyool-boo-DAH-ghee-an) is a reflection nebula in the northern constellation Cepheus, located about 1.5 degrees west of the much brighter reflection nebula NGC 7023. The light illuminating it comes from the T Tauri star PV Cephei.
NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. [2] A recent survey indicates the cluster contains more than 130 stars less than 1 million years old. [citation needed] NGC 7129 is located just half a degree from nearby ...
The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars , which live for billions of years) stars are present in a small, circular cavity ...
NGC 7380 is a young [4] open cluster of stars in the northern circumpolar constellation of Cepheus, discovered by Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25′.

NGC 7160 is an open cluster in the constellation Cepheus. It was discovered by William Herschel on November 9, 1789. The cluster was also observed by John Herschel on October 7, 1829. It is a poor cluster and with little central concentration, with Trumpler class II3p. [5]
DH Cephei is a variable binary star [5] system in the northern circumpolar constellation of Cepheus, positioned about two degrees to the east of the star system Delta Cephei. [10] With an apparent visual magnitude of 8.61, [3] it is too faint to be visible without a telescope.
