Crescent Nebula and Soap Bubble (SV130)

A week of clear skies yielded a nice opportunity for me to continue to run both my refractors from my Bortle 8 driveway. I've imaged the Crescent Nebula way back when I first started, so it was very rewarding to come back to it now that I have better equipment, data, and processing skills. I got some of the Soap Bubble in the frame, which I did not expect, and I got some of the OIII loop that extends from the main Crescent - though, I avoided over stretching it for the sake of the background. I now see the value of getting extra time in OIII on this target for the details.

More time would also probably help StarNet do a better star removal. I had to stretch all mono images first before StarNet produced a reasonable star mask and starless image. Otherwise, the starless images were full of holes. But, doing the stretch and then star removal worked very nicely, especially in Ha. I also tried Bill Blanshan's pixel math scripts for HSO and SHO combinations. I included a few permutations in this submission, as I can't really decide which I like best. I like the cloudy nebulosity of the SHO combination but the Cresecent color and definition in the first HSO combination. C'est la vie. Enjoy.

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.
