Revision title: Lobster Claw Nebula (Sh2-157)

I chose SH2-157, also known as the Lobster Claw Nebula-I think you can see why. This nebula is an emission nebula located about 11,000 light-years away near the edge of the northern constellation Cassiopeia bordering on the constellation of Cepheus.

Title: Lobster Claw Nebula (Sh2-157) Rev1

Description: Re-Visited the processing of this. The stars in the first one were a little wonky! I got a little zealous with Blur XTerminator. Dialed back some of the settings especially the star halo adjustment (More is not always better). The stars in this one are 100% better. For a minute I thought I had a camera fan vibration issue. Still can dial in the back focus a little more and will do this the next clear night.

Title: Lobster Claw Nebula (Sh2-157)

Description: Weather has been horrible as I am sure it has been for most in North America. I purchased a copy of Affinity Photo and have been getting used to it as a final processing software after Pixinsight. Seems I am getting the hang of it so I visited some older data. Lobster Claw was one and I think it pops just a little more.

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.
