Lobster Claw Nebula in SHO

This is another example of data I have had on disk for a long time: 2.5 years in this case. I'm spending my time these bright summer days going through the back catalogue. This one was well worth doing in my opinion.

There are several objects classified in Beverly Lynds' 1965 catalogue of bright nebulae (Lynds' Bright Nebula, LBN) but the whole region is identified as Sh2-157 in the Sharpless catalogue of HII regions. There is also a small star cluster at the top right, NGC 7510.

This nebula, commonly called the Lobster Claw nebula, for obvious reasons, is close to the Bubble Nebula, which is out of the frame to the upper left.

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.
