PACMAN NEBULA (NGC 281)

The Pacman Nebula (NGC 281) is a cosmic cloud of space gas rich in Hydrogen Alpha (red/orange) and Oxygen (blue) located in the constellation Cassiopeia. It gets its name from the classic video game character it resembles. NGC 281 is a rather diffuse red-glowing emission nebula. It includes a small, yet noticeable open star cluster (IC 1590) and some really dynamic dust lanes. The prominent lane of dark dust cutting into this glowing nebula creates the “mouth” of this nebulas shape.

The Pacman Nebula contains Bok globules, which are small and isolated dark nebulae containing dense amounts of dust and gas. These collections of cosmic gas and dust are often followed by the formation of new stars.

Captured with 14.5 hours of narrowband data under a near full moon and Bortle Class 4 skies near downtown Flagstaff, Arizona.

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.
