West of Iris (LBN 468)

On the border between Cepheus and Draco, and just west of the Iris nebula (NGC 7023), is this complex of nebulae usually relegated only to appearing in wide-field photographs of its famous companion.

The main structure is cataloged as LBN 468, an HII (ionized hydrogen) region, on which dark clouds are superimposed, including LDN1158 in the upper left corner, as well as LDN1147 and LDN1148, parallel and similar in shape, to the left of the center.

In the upper central part, LDN1152 stands out, a dark structure in the form of a loop, which houses a young star cataloged as IRAS 20359 + 6745, which partially illuminates the nebula.

North is up.

Capture made during three consecutive nights. The technical problems of the first night were corrected for the rest but the entry of clouds and haze from North Africa complicated the sessions. Also had some issues with the coordinates on KStars Scheduler, so many of the subs are slightly mis-framed.

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.
