- Deepsky 550mm RGB-SHH
- Area Constellation Cassiopeia / Cepheus

Sharpless 2-157, also known as the Lobster Claw Nebula, is a bright emission nebula located in the constellation Cassiopeia. It is located not far south of the better-known Bubble Nebula (NGC 7635). There are numerous other objects within the nebula, such as the planetary nebula PLN 110-0,1 in the center of the upper right quadrant. The bright patch of nebula near the center of the image is Lyns bright nebula 537 (LBN537), also known as Sharpless 2-157a. Above the lower pincer is the small star cluster Markarian 50 and above the upper pincer the bright star cluster is the open star cluster NGC 7510.

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.
