Sh2-157 Lobster Claw and Surrounding Area SHO+RGB

This three degree wide astro image contains a slew of interesting objects. On the left side is Sh2-157, the Lobster Claw Nebula, an emission nebula in the constellation Cassiopeia. A ring nebula Sh2-157a and a Wolf-Rayet star WR157 reside within the lobster claw and an open cluster NGC 7510 can be seen just below the lower claw. Nearby is the Bubble Nebula NGC 7635 (in the upper right quadrant) with its striking clear, round shape. In the upper right corner is the open star cluster M52. NGC 7538 (in the lower right quadrant) is home to the biggest yet discovered protostar, estimated to be 300 times the size of our solar system. Sh2-159 is a small HII region located centrally among its prominent neighbors and beautiful in its own right, but sadly must feel like it is included in the photograph only because it lies so close to these photogenic targets.

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.
