Revision 4/2023:

A very early image. This was revisited with the newer process and tools. At least the colors were chosen by SPCC. Hoping that makes that more accurate. Also, noise reduction by NXT. Some stronger star reduction to bring out better the faint RF fog that appears to really exist around the center of the image in association with the dark nebulosity. Elongated stars in the subs means that I got some star doubling on the right lower edge. This was long before I tried to fix the backfocus and tilt in my system. Unlikely I will revisity this anytime, so trying to make this look a bit better. Also, being an old image, I decided not to fix the star halos. This is one of very few images that SXT failed me! So many stars, they run into each other and SXT sees them as small nebulae. In comparing the two images, the new fixes appear to add depth to the field. Seems more real. But for me, the most important part is the clearer view of the two smallish reflection nebulae in the field. Still not easy to find, but I will let anyone test their, "Where's Waldo" skills should they stumble on this very old image!

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.
