Sh2-157 The Lobster Claw Nebula

First pass through the data in natural color.
This fov has got to be one of the coolest that I have imaged so far. There is so much going on!
The Lobster Claw Nebula (Sh2-157) is the highlight of this image. But, there is so much more to see!
The Bubble Nebula (NGC 7635), star clusters M52, NGC 7510, and MK50, and emission and reflection nebula NGC 7538 that contains the biggest yet discovered protostar which is about 300 times the size of the Solar System.
I tried a few other different coloration's, but the original natural color is what I prefer for now.
I’m sure that I will try a few more!
Thanks for looking!

Description: A rework of the data using Bill Blanshan's pixelmath HOO normalization.
Also, a first try at adding RGB stars. There are a few halo issues there that I need to work out. Also some saturated stars with only 15 sec exposures! Need to reduce that time.
Thanks for looking!

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.
