NGC7635 / SH2-157 / M52

Halfway between the constellations of Cassiopeia and Cepheus, you'll find a magnificent group of celestial objects. We have, the most well-known, the Bubble Nebula, NGC 7635, but also the Lobster Claw Nebula, SH2-157, to its left, then another emission nebula, SH2-161, equally large to its right, not to mention the two smaller ones below, SH2-159 and NGC 7538. We also have two open clusters with the largest one being part of the Messier catalog: M52, the Salt and Pepper Cluster, and finally the smallest: NGC 7510, the Dormouse Cluster at the bottom left, located in the constellation of Cepheus.So, there are no less than 5 nebulae and 2 clusters in a field measuring 3°37 by 2°44 with a 280mm focal length coupled to an APS-C sensor (small format). This image required 45 hours over 5 nights and processing with an SHO palette, meaning the sulfur layer (SII) for red, the hydrogen layer (H-alpha) for green, and the oxygen layer (OIII) for blue.

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.
