IC 1318 - The Butterfly Nebula

IC 1318 (aka Gamma Cygni Nebula or the Sadr Region)

From wiki: IC 1318 is the diffuse emission nebula surrounding the star Sadr (γ Cygni) at the center of Cygnus's cross. The Sadr Region is one of the star's surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula (not seen in this photo). It contains many dark nebulae in addition to the emission diffuse nebulae.

Sadr itself has approximately a magnitude of 2.2 (very bright) and 1800 light years away. The nebulous regions around the region are also fairly bright.

This image was captured over three nights from my backyard in the Portland Metro Area.

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.
