SH2 8 - The Cat's Paw Nebula

SH2 8, also known as NGC 6334, Gum 64, RWC 127, The Cats Paw Nebula, or the Bear Claw Nebula.

This is the lowest declination target I've attempted, which presented all kinds of challenges. In addition to having a short window each night due to trees and rooflines, the EAF would frequently fail to auto-focus leaving me with stacks of blurry images. The weather has also been an issue recently, with a marine layer coming in around midnight each night to end my sessions early. However after a full month, I finally had enough to create the image I was going for.

There is a lot of Ha and SII in this target, but not much OIII. I think the image still looks a bit too green, so I may post a revision later with some hue shift or alternate palette.

Stacking in Siril with 2x drizzle, gradient removal, and RGB color calibration. Star removal with content aware fill in photoshop, followed by levels/curves, and camera raw filters.

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.
