Not much information about this object is available online; I suppose that is because it's just like so many other lightly stimulated nebulae. It is mostly Ha with a bit of SII and barely enough OIII to show.

The subs for this object had apparent horizontal banding, which I partially remediated but still persisted in the final image. The more the colors and brightness were enhanced, the more noticeable they became. Perhaps this was a positive fact because it drove me to be less color-aggressive, my natural pension, and produce an image of a different ilk. Compare it to my last image on Astrobin, which used the same scope, filters, color mapping, camera, etc.

Let me know what you think…

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.
