Sh2-157 Lobster Claw Nebula

Sh2-157 Lobster claw nebula, with the bubble nebula top right as a size comparison. I'm pretty pleased with how this one came out.

According to skyandtelescope
Sharpless 157, also known as the Lobster Claw Nebula, is a bright emission nebula in the constellation Cassiopeia. It lies just south of the better-known Bubble Nebula (NGC 7635). Within this image are a few other objects. Planetary Nebula PLN 110-0.1 is located near the center of the upper-right quadrant. The bright nebular spot near the center of the image is Lyn's Bright Nebula 537 (LBN537), also known as Sharpless 157a. The small cluster of stars just above the bottom pincer is Markarian 50 and the bright cluster of stars located above the top pincer is open 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.
