In the constellation Cassiopeia is a bright emission nebula, NGC 281, commonly called “Pacman Nebula.” In the center of the nebula is a star cluster, IC 5090, whose young, hot stars are generating intense solar winds that are sculpting channels and pockets in the surrounding gas and dust. Along the perimeter are a collection of Bok globules, as well as a large dust cloud that forms a dark slash into the cloud.

Collecting the data for this image was frustrating. While I was fortunate to have a string a clear nights, the quality of the sky made for very uneven HFR values, ranging from 1.8 to 4.8 within the course of six hour sessions. In total I captured nearly 30 hours of data, but employed only about the best 17 hours for this image, data with of HFR 2.8 or less. I created a master luminance with Ha, OIII, and SII data whose HFR was 2.3 or less.

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.
