Sh2-280 (2021)

This emission nebula is located 5000 light years away in the constellation of Monoceros at a declination of +2 degrees. It spans about 0.5 degrees, equal to the size of our full moon. The nebula has a width of 40 light years and is located 2 degrees south of the much brighter Rosette Nebula.

Despite being a nice object in full narrowband, there are only a couple of full narrowband images of this object on Astrobin. My favorite part is the blue bow shock wave to the right of the central bright ionizing star HD 46573.

Subtle but fascinating to me is the bright SII region, seen in ruby red, surrounding the bright star HD 47220 on the left side of the image.

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.
