NGC7023 - Iris Nebula
Reflection Nebula, in Cepheus, surrounded by dark molecular cloud. About 1,300 LY away and 6 LY wide.

This image is from data captured in 2019. Despite what I then thought were good subs, I was never happy with the final image, so - for the first time - I am reprocessing older data. I now have 3 more years of PixInsight familiarity, an improved PixInsight distribution (GHS, SPCC … ), and have embraced RC Astro's AI processing tools - specifically NoiseXTerminator, BlurXTerminator and StarXTerminator. While I have some level of comfort with TGVDenoise , Deconvolution and mask creation, the AI tools do a faster and superior job than my meagre skillset. (Computers are still just a ‘bit’ smarter.)

The 2019 image is below. The difference in the Iris Nebula 2019 vs 2022 image is not subtle - hard to believe it is the same data. Looking forward to the 2025 version.

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.
