The Clamshell Nebula

So what do you do when you have a couple of clear nights with a near full moon, you capture NB. Sh2-119, known as the Clam Shell nebula. I guess I can see where they came up with the name, but I think it is a bit fishy. But seriously, this is a large emission nebula that gets a bit overshadowed by nearby neighbors the North American and Pelican Nebulas. This area also has several Lynd’s Bright Nebulae and Lynd’s Dark Nebulae and a Open Cluster (NGC 7044) that is about 11,000 light years away. The bright star in the center is 68-Cygni. Similiar to the North America nebula, this gas cloud is about 1,800 light years away.

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.
