Iris nebula in widefield, unguided

Another image from our novel dark site, east of our city. I took advantage of the clear northern skies to image this beautiful nebula.

Integration was not long at 25 x 120 seconds, 800 ISO. The same evening I shot M17 and finally, Neowise.

The Iris Nebula is a remarkable reflection nebula that resides in the constellation Cepheus and includes obvious patches of dark interstellar dust in the area.

NGC 7023 is relatively bright when compared to other reflection nebulae at magnitude 6.8.

NGC 7023 is the star cluster within the nebula. The nebula glows blue thanks to output from SAO 19158.

Description: A crop of the main image, but I tried to leave the interesting dark segments of the surrounding region about the nicely lit central "iris".

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.
