NGC 7380 Wizard Nebula #4

I am *very* pleased with how this one came out! It's a combination of images from my Ohio backyard and the Okie-Tex Star Party. (Believe it or not, the background is still higher from the city in narrowband, even at 3nm bandwidth!)

NGC 7380 is actually the designation of the star cluster; the associated nebulosity prominent here was discovered by Caroline Herschel in 1787. The Wizard Nebula lies 8,500 lightyears away from us in the northerly constellation Cepheus. It spans an area 25 arcminutes wide, or about the size of a full Moon.

This is an emission nebula, where various gases from long-dead stars are forming new ones. The colors assigned to the narrowband images right around the wavelength these gases emit at are red for sulfur, green for hydrogen, and blue for oxygen -- in reality, both sulfur and hydrogen glow a deep red, while oxygen glows a teal-blue, so to tell apart the sulfur and hydrogen, we use a false color palette often employed by the Hubble Space Telescope.

I'm really happy with how the colors came out! I utilized some AI-powered tools, BlurXterminator for sharpening (deconvolution really), and NoiseXterminator for some late-stage denoising where my other methods just weren't quite getting it right.

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.
