NGC7023: The Iris Nebula

NGC7023 - The Iris Nebula is a bright reflection nebula in the constellation Cepheus. Reflection nebulae are clouds of interstellar dust that reflect the light of nearby stars. The frequency spectrum shown by reflection nebulae is similar to that of the illuminating stars. It is about 1,300 light-years away and is six light-years across.
This is an object I keep coming back to and adding in more data. I am just starting to get the very faint dark clouds that are surrounding the Reflection Nebula.
I have not done that much processing to this, other than some minor stretching and increasing the saturation to bring out what little color there is.

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.
