IC1318 - The Gamma Cygni Nebula (aka Sh2-108)

Estimated at 5,000 light years distant, the Gamma Cygni region features newly-formed stars, vast streaks of light-blocking dust, and glowing nebula along the plane of our Milky Way. Gamma Cygni, the massive F8 supergiant star located off-center in the frame, actually lies much closer to Earth at only 750 light years. This massive star is 150 times the size of the Sun and forms the center of the constellation Cygnus, the Northern Cross. Due to its bifurcated shape, this portion of the Gammy Cygni nebula is often called the Butterfly Nebula.

This image is a combination of 29 hours of camera exposure using a set of narrowband light filters. These filters transmit only a small fraction of visible light wavelengths, each tuned to the wavelengths associated with the energy released by sulfur, hydrogen, and oxygen atoms, respectively. This “SHO” combination is frequently known as the “Hubble Palette”, originally developed for color mapping of images produced by the Hubble Space Telescope.

This image has been drizzled 2x to make up for the native 2.3"/pixel resolution. I think it did a nice job.

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.
