Pacman Nebula, NGC281, in Narrowband

This is the Pacman Nebula, imaged in narrowband. I had what seemed like unusually noisy OIII data on this one; in retrospect I think I probably just got overly aggressive in stretching it. The orientation of the object is also not ideal with respect to the camera chip, not something I could easily fix when imaging remotely. But I am happy with the result, as the colors and detail are what I was hoping for. This image was processed as a starless nebula with the additional RGB data being used for stars. Interestingly, even the small amount of RGB data produced a passable RGB version of this image that I may decide to post here at a future date.

This object is an emission nebula in located approximately 9200 light years away in the constellation of Cassiopeia.

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.
