Sh2-112 #1

Another backyard shot -- emission nebula Sh2-112! A member of the Sharpless catalog, this nebula is located in the constellation Cygnus, which is rich in both stars and emission nebulae. It's only 1.5 degrees away from Deneb, but it's 5,670 lightyears away from us.

Despite how much light pollution I have around here, getting good images is made easier with narrowband filters, which pass only small slices of the light spectrum where gases in space tend to glow. In this case, I'm using the Optolong L-eXtreme filter with my color astro camera, my ZWO ASI294MC Pro. It passes red-glowing light from hydrogen and blue-glowing light from oxygen. So the star colors turn out mostly red and blue, but it ends up making a mostly-natural-looking color palette without me having to manipulate it very much.

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.
