NGC 281 SHO the PAC-MAN Nebula

NGC 281, also known as IC 11 or Sh2-184, is a bright emission nebula and part of an HII region located about 9200 light-years away in Cassiopeia.

This 20×30' sized nebulosity is also associated with the open cluster IC1590 and is a star-forming region that contains young stars, large dark dust lanes and Bok globules. Bok globules are small, dense dark nebulae packed with material from which new stars are formed. The dark dust lane spreads unevenly across glowing clouds of hydrogen and its appearance suggests that it being sculpted by a massive star in the background, concealed by the dark clouds.

At the center of the Pacman nebula, the star system catalogued as B 1 is composed of an O-type star with an apparent magnitude of 7.8 and four companions. The companions are separated by 1.4 to 15.7 arcseconds from the primary.

Luminance layer is a mix of Halpha, Oiii and Sii filters and i am quite happy with the faint extensions that came out :-)

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.
