SH2-157 Lobster Claw Nebula

Sharpless 157, the Lobster Claw Nebula, is a bright emission nebula in the constellation Cassiopeia at a distance of about 8,000 light-years. It is only a short distance from the famous Bubble Nebula. The small open cluster of stars located in the lower right of the image is designated NGC 7510 and lies approximately 11,400 light-years away.

With this image I feel I snatched victory from the jaws of defeat. Operator error lead to hardware issues, coupled with using NINA & PHD2 for the first time resulted in a lot of bad data. Fortunately the conditions cooperated at the SDAA dark site (Tierra Del Sol) and I was able to capture more subs than I had planned. I am not sure what caused the diffraction spikes in the upper part of the image.
I am most grateful to Ron Brecher (AstroDoc) for showing me processes and scripts in PI to get the most out of my data.

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.
