Starless and Starry Crescent (dheilman)

Starless and Starry Crescent

This is data that I had stockpiled since the summer. I’ve been on a kick with these starless images as I’ve been fully tone mapping most of my stuff. Some of them don’t work out well for starless finish but others do. Don’t know what to think of this but I hadn’t ever seen a starless version of it before so I thought I’d share both versions.

The Crescent nebula, NGC 6888 is the product of the tremendous stellar winds of a Wolf-Rayet star. These relatively rare stars are massive, young, and highly luminous. Gasses cast off during formation of the star are overtaken by intense radiation and fast stellar winds causing a shock wave to form. Visible are the hydrogen gas of the nebula and surrounding areas (red) as well as an oxygen envelope surrounding the nebula (blue).

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.
