NGC 281 - Pacman Nebula

Went to a Bortle 4 sky and had one good night to shoot. Unfortunately, I couldn't shoot each target that long but I'm very impressed by the amount of details I could pull with such little data.

The Pacman Nebula (NGC 281) is a large emission nebula appearing near the orange giant Schedar in the constellation Cassiopeia. The nebula lies approximately 9,200 light years away and occupies 35 arcminutes of the apparent sky. It was named the Pacman Nebula for its resemblance to Pac-Man, the character in the popular 1980s maze video game. In optical images, a dark dust lane forms the Pac-Man’s mouth.

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.
