Swan Nebula, 2023

Revision title: HSO processed mostly in photoshop

The Swan Nebula is between 5,000 and 6,000 light years from Earth and it spans some 15 light-years in diameter. It is considered one of the brightest and most massive star-forming regions of our galaxy. The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these young stars; however, the actual number of stars in the nebula is much higher than in the Orion Nebula – up to 800 in the Swan.

I was not happy with any of the standard color combinations, so this is an OSS with Ha for luminance.

Title: HSO processed mostly in photoshop

Description: Recently there have been a few TAIC sessions with folks who produce very good images, and I noticed a common thread of leaning more on photoshop than I have been recently. I've gone back and replayed a couple of the presentations, and then have gone back and played with old images to try some of these techniques. This is an example of a re-process, done mostly in Photoshop. Not only is the color scheme significantly different (FORAXX in the original, vs HSO here), the sharpening is better controlled and the crop is tighter with, I believe, better composition

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.
