Sh2 46

Standard minimalist processing. Have learned a lot about star coloring... this is a bit overdone to make the point.

RGB stars isolated in PI then saturated and added back to destarred Ha (red channel only) in PS using linear dodge to the RGB star later.

Prior CCD version:

Sh2 46

From GalaxyMap:

This isolated nebula is located well above the galactic plane.

Avedisova concludes that it is ionised by the potential runaway O9.5 Iab supergiant HD 165319, which may have been ejected from NGC 6611, the central star cluster of M 16, the Eagle nebula, about 1.8 million years ago.

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.
