IC 5146 Cocoon Nebula in Ha

The Cocoon Nebula is a reflection/emission nebula in the constellation Cygnus. It shines at an approximate magnitude of 9.0. The nebula is about 4,000 light years away, and the central star that lights it formed about 100,000 years ago; it is about 12 arcmin across, equivalent to a span of 15 light years. [Source: adapted from Wikipedia]

The Cocoon Nebula is an HII region, where a central young, bright star illuminates the ionized hydrogen gas, causing it to shine. Some young stellar objects are visible as bright spots along the main filaments; many other young stellar objects are located within the Nebula. [Source: adapted from ESA]

This would be a far better image if taken with a bigger telescope than my little 2.6". When I can work up the courage I will put the Atik + OAG on my AT8RC. A chronic problem, now that I'm doing OAG guiding, is LP here makes finding guide stars hit-and-miss.

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.
