Sh2-155 Cave Nebula SHO+RGB

Sh2-155 (also Caldwell 9, Cave Nebula) is categorized as an emission nebula but is contained within a much larger nebula complex that includes emission, reflection and dark nebulosity. To Patrick Moore, the bright portion of the nebulosity resembled the mouth of a cave prompting him to use the name when he compiled his Caldwell catalogue in 1995 -- even though a nearby unrelated reflection nebula, CED 201 (also in Cepheus) was already known as the Cave Nebula. Today, the twice-used name has become more associated with Sh2-155. (Source: Wikipedia)

The Cave Nebula by itself is a rather small target for my much wider field of view. I felt that the extended nebulosity surrounding the Cave however was interesting and that it provides a natural extension to be viewed with this deep sky object.

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.
