IC1396A and Surrounding Nebulosity in Cepheus

The area of nebulosity imaged here is commonly called the Elephant's Trunk nebula. The trunk itself is cataloged as IC 1396A. It is a very dense, elongated region of dust and gas globules, approximately 20 light years (LYs) in length. It's appearance resembles an elephants head and trunk, with a bright surrounding halo of gas. It is located some 2,450 LYs from Earth. The trunk is a region of star formation, with some 250 known young stars, some as young as 100,000 years old.

Located close to the center of the image is the relatively faint emission nebula IC 1396. The star responsible for it's blue glow is the multiple star system HD 206267 . IC 1396 contains a number of globules similar to IC 1396A (Elephants Trunk).

The bright star on the right side of the image is the red supergiant Mu Cephei. It is known as Herschel's Garnet star. It is one of the largest, as well as one of the reddest stars in our sky. It has a radius of 1,260 -1,650 times that of our sun; if positioned in the center of our solar system, it would extend past the orbit of Saturn.

Directly below Mu Cephei is a small (in my image) pretty OIII emitting planetary nebula cataloged as PK100+04.1.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
