NGC 7023 is the famous Iris Nebula in Cepheus. This image was taken from my Bortle 4 backyard with the Esprit 100ED Super Apo on several nights in July-August 2020.

Title: 2022 Re-process with Starnet++ and Topaz AI

Description: I decided to reprocess this image with Starnet++ to keep the star halos in check and permit independent stretching of the nebula. I also used Topaz AI to tame the noise, since this image was taken during warm weather and the noise levels were higher than I would have liked for 15 hrs. of integration. I know Topaz AI is not everyone's favorite software, but it can do a nice job on a starless image if the AI sharpening is completely turned off, as I did here.
