M16 Eagle or Star Queen Nebula

M16, the Eagle or Star Queen Nebula is situated about 5,700 light years away. It contains the famous "Pillars of Creation", pillars of hydrogen gas where new stars are being born.

This image could use more integration time but clear nights are few and far between at the moment and I was keen to try out the Dynamic SHO approach suggested at thecoldestnights.com. The stars are pseudo RGB using R=Halpha; G=.2*Halpha+.8*OIII; B=OIII. The stars were extracted using the "unscreen" option in StarXTerminator, then "screened" into the processed starless SHO 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.
