Caldwell 4, The Iris Nebula A reflection nebula located in the constellation Cepheus
The designation NGC 7023, is the open cluster within The Iris nebula
I got three nights in October 2023 on this object, mostly at the same time I collected the photons from the Heart and Soul and the last week I´ve been doing several iterations of this image to get the best possible result.
This is my first image of this reflection nebula AKA the Iris nebula/ LBN 487/Caldwell49, shrouded in LDN 1174 and surrounded by quite a few of other LDN objects.
I had a lot of work pulling out the details in the Lynds Dark nebulae as there is not much contrast between the dark nebula and the dark background.
I don`t know if it I got it right, but feel free to comment.

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.
