A reflection and emission nebula in the constellation Cygnus.
The darkness around the nebula is due to the dark interstellar dust that surrounds it.

The aptly named Cocoon nebula is featured in this image from NASAs Wide-field Infrared Survey Explorer, or WISE. This cloud of dust and gas, cataloged as IC 5146 and located in the constellation Cygnus, is wrapped in a dark cloud of dust called Barnard 168. Within this cocoon of dust and gas, new stars are forming and beginning to emerge into the wild.
In the heart of the nebula, which looks surprisingly like a Valentines heart in WISE's view, massive new stars are emerging. The intense radiation from these stars heats up the cloud. The highest-energy light from the stars rips electrons from hydrogen atoms, which then recombine with the atoms and emit visible light.
Pictures of the Cocoon nebula taken with visible light see only the inner most part of this cloud glowing red and surrounded by an eerie darkness. That darkness appears as an absence of stars, but it is actually a dense cloud of dust obscuring stars behind it. This dense cloud is being heated by the young stars within. The dust absorbs the high-energy radiation from the newborn stars and then glows in infrared light, captured by WISE in this view. The dusty cocoon extends over 45 light-years across, which is more than three times larger than the inner, glowing portion of the nebula.
The colors used in this image represent specific wavelengths of infrared light. Blue and cyan represent light emitted at wavelengths of 3.4 and 4.6 microns, which is predominantly from stars. Green and red represent light from 12 and 22 microns, respectively, which is mostly emitted by dust.

clouding over... a rush job..but very pretty and deserves a real effort.

IC 5146, also Caldwell 19, and the Sh 2-125, Cocoon Nebula, is a reflection emission nebula and Caldwell object in the constellation Cygnus. IC 5146 is a star cluster and the nebula is Sh2-125. It shines at magnitude +10.0 Its celestial coordinates are RA 21h 53.5m, dec+47° 16′. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equavalent to a span of 15 light years. When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.

Imaged in broadband RGB from Chuchupate Campground on 8/10/24, using APM 140 doublet at f/5.6, asi2600mm, and Astronomik MaxFR color filters. 7 hours total integration.
Photo taken using a Nikon D40 attached to Skywatcher ED80 refractor. Exposure is of 13min 33s. Composite image, no dark frames. No autoguiding was used during the taking of the images. Processing was done using DeepSky Stacker and GIMP.

Taken from my backyard (Bortle 6) on the night of September 22, 2020)
This was a rare photo where PHD Autoguiding worked. I think either Orion, PHD2, or Windows did something wrong where my autoguiding software will stop guiding after a couple of minutes and give bogus error messages. I'm thinking maybe if I downgrade to an older version of PHD, I might get things working again.
Either way, I likely should not have shot at ISO800/300mm/4min and maybe should have done ISO1600/420mm/4min. Noise levels seemed very disappointing for ISO800, but maybe the 4min frames in conjunction with July caused all the noise.
The 7D Mark II is also bad at low light astrophotography. It has a seemingly well known (with astrophotographers) low light banding problem that Canon won't admit. The 5D Mark IV kills it on noise levels, which will be shown in a future yet-to-be processed clean image w/ the 5D4.

I totally forgot I did this one. This is an emission nebula in the constellation of Cygnus. It is about 15 light-years across and roughly 4,000 light-years away. You can also see a dark nebula, Barnard 168, as well. This is actually clouds of dust that are blocking the light from the background stars and giving the impression of empty regions in space.
