Emission Nebula Sh2-140 (LBN 505)

Sh2-140 is a hydrogen emission nebula located approximately 3,000 light-years away on the edge of a ring of molecular gas and dust known as the Cepheus Ring. From what I can tell in the literature, Sh2-140, refers to the more dense star forming the bottom edge of the nebular complex while LBN 505 is the nebula as a whole. Larger telescopes can reveal some of the star formation detail in the Sh2-140 region especially using IR filters.

There are many other objects in this field such as reflection nebulae, a star cluster, and colorful stars. The bright yellow star on the right is known as 25 Cep (25 brightest star in Cepheus). Up near the top the bright blue star has some blue reflection which also seems to be associated with an emission nebula, LBN 500. On the lower right side of the image there is another blue reflection nebula named vdB 153 which is adjacent to reflection nebula LBN 508.

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.
