IC 5146, Cocoon Nebula

About 3500 light years distant, IC 5146 is an emission and reflection nebula within a star forming molecular cloud. The cloud itself spans over 2 degrees of sky, and is thought to be about 15 light years wide. The brightest central star is blowing a hole in the cloud, and pressuring other star forming activity in close proximity.

In this view, I've captured a bit over 3 hours @ f/2.2. The TAAA CAC site has Bortle 1-2 skies in southern AZ. I captured a minor portion of the data last year at home, and the majority of the data this September and October at CAC. All told, there are 405 exposures of 30 secs. Seeing wasn't great, but acceptable (avg=3.14).

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.
