Mu Cephei / Garnet Star Region - a photo on Flickriver

Mu Cephei / Garnet Star Region

            This is a picture I took in 2019 of the Garnet Star region, at a focal length of 70mm. There are lots of objects in this picture, starting with Mu Cephei (or Herschel’s Garnet Star or Erakis) and ending with lots of dark nebulosity areas.

Mu Cephei is a red supergiant star in the constellation of Cepheus, maybe the reddest in the northern hemisphere. It’s a variable star with a period of about 755 days. Maybe one of the most interesting facts I’ve read about this star is that its spectrum shows water-vapor bands!

Mu Cephei lies at the edge of a large emission nebula known as IC1396. The most famous feature is The Elephant’s Trunk Nebula, a star-formation region that looks like an elephant’s trunk in photos.

There are lots of other emission nebulas in the picture (the red areas), as well as dark nebulas, and some open star clusters.
