******************************************************************************

Photographed at Algonquin Provincial Park, Ontario, Canada

(275 km by road north of Toronto)

* Temperature 15 degrees C.

Total exposure time: 10 minutes.

This is a large and quite faint emission nebula and star forming region over 100 light-years across, located about 2,400 light-years away in the constellation Cepheus. It is energized by the bright, bluish central multiple star. The very small Elephant’s Trunk nebula (IC 1396A) is inside the dark elongated globule just to the lower left of the centre of the bright gas cloud.

From one web site: "The brightest star (38,000 times brighter than the Sun) ... [at the lower left edge of the nebula] is mu Cephei. It is a red supergiant star with a diameter larger than the orbit of Saturn, some 2536 times the diameter of the Sun. It is one of the largest stars we know of. Also called Herschel’s Garnet Star, mu Cephei is a variable star that varies in magnitude from 3.4 to 5.1 over a period of approximately 730 days."

At the upper left edge of the frame is part of a large, faint reddish nebula called the "Flying Bat" (also known as Sh2-129).

Near the left edge is the bright star Alpha Cephei (also known as Alderamin), which is the brightest star in the constellation Cepheus. It has 2.3 times the diameter of our own Sun, and is 17 times as bright.

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.
