Celestron 1100HD on CGEM DX. QSI 640 with Maxim LE. Six each of RGB at 5 minutes and 2x2 bin. Nine luminance at 10 minutes and 1x1 bin. Used DeepSkyStacker to stack the four sets separately and then used GIMP to combine the R, G and B images into single shot. Then converted RGB -> YUV and replaced Y with luminance shot, finally converting back to RGB.
Love the new camera - even with relatively few subs I get the Cocoon with almost no noise!
Integrated flux nebulae are visible in the field, and Sivan 2 shows vast red ring and green haze in the south part of the constellation Cassiopeia.

WISE image of the constellations Cassiopeia and Cepheus and lots of interesting gas/dust clouds, nebulae, stars, and other astronomical objects.
Original caption: This enormous section of the Milky Way Galaxy is a mosaic of images from NASAs Wide-field Infrared Survey Explorer, or WISE. The constellations Cassiopeia and Cepheus are featured in this 1,000-square degree expanse. These constellations, named after an ancient Queen and King of Ethiopia in Greek mythology, are visible in the northern sky every night of the year as seen from most of the United States.
To the unaided human eye, Cassiopeia is easily recognizable by the five bright stars that make up its W shape. However, WISE observed infrared light, where the sky takes on a very different appearance. The bright stars of the constellations fade into obscurity amongst the backdrop of millions of other stars revealed by WISE. Cool clouds of dust that fill the space between the stars in the Milky Way glow in infrared light and tell us more about the story of how stars are born, and how they die.
Within this image are dozens of dense clouds, called nebulae. Many of the nebulae seen here are places where new stars are forming, creating bubble like structures that can be dozens to hundreds of light-years in size. The process of star formation within these giant clouds has been likened to fireworks, celebrating the birth of new generations of stars. But the death of stars is also seen in the remnants of a supernova explosion that was witnessed by the astronomer Tycho Brahe in 1572 AD. This remnant is located about 1/5th of the way from left of center and about 1/6th of the way up from the middle of the image.
This portion of the Milky Way has been a favorite place for selecting previous featured images from WISE. Some of the notable featured images which lie within the region are: the Wizard Nebula, a Cosmic Rosebud, the Heart & Soul Nebulae, the Pacman Nebula, Tychos Supernova Remnant, and the final frame observed by WISE.
The colors used in this image represent specific wavelengths of infrared light. Blue and cyan (blue-green) 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. This image is a mosaic of thousands of individual frames from WISE, combined first into 442 interlocking tiles before reprojecting and stitching them into the final picture. This was done for each of the four WISE wavelengths, totaling nearly 30 billion pixels in the interlocking tiles.
Canon 5D3 with Celestron CGEM 1100HD and 0.7x reducer. Stack of 21 images at ISO 800 and at 10 minutes exposure, each with dark frame. Manual Guiding with Celestron off-axis guider and Orion's 12.5mm illuminated reticle eye piece.
The very dim surface brightness, haze and the 5D3 IR filter all combined to make it very difficult to get the H II region without noise. Still, the seeing was the best yet so the stars are fairly pin-point. The 0.7x reducer is both very good and very heavy (big chuck on glass!). Very little coma in the corners, some small amount of chromatic abberation (but that is correctable in software).
The cocoon is is about 12 arc-min across (about 1/3 size of the moon) and is both a reflective and emissive region being driven by the young star (100k years) in the middle. The darker blotches surrounding it (areas of fewer stars) are the result of dust, part of a dark lane that surrounds the nebula.
LRGB (380💯100) 11.3 total hours of exposure. 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.

The Cocoon Nebula (IC 5146) is an Emission/Reflection Nebula in the constellation of the Swan (Cygnus). It is embedded at the end of a long dark nebula (Barnard 168) which surrounds and then extends slightly from the Cocoon to the left then straight up out of the top of the photo. It is evident by the reduction of stars present.
In addition, the Cocoon is associated with the Open Star Cluster (Collinder 470) of which the bright star (BD+46 3474, a B subgiant) at the center of the nebula provides the energy to force the surrounding gases to glow.
Photo taken with a ZWO Seestar, where 10-second exposures were combined for 93-minutes on the morning of July 2, 2024. Processing help provided by Jim Johnson.
Nebula with surrounding dust (dark nebulosity) about 4000 light years away, in the constallation Cygnus. The central illuminating star is very young...only about 100,000 years old. Humans were on Earth when this star was born!
This image is a lot of "firsts" for me...First light with the new camera, first time trying LRGB method (versus one-shot-color camera), and first time using PixInsight.

This nebula, embedded in the Milky Way at the north end of Cygnus, appears to have cleared a path through the stars. That is not possible. A more reasonable explanation is that, at about 4,000 light years away, it is closer to us than most of the stars in the photo and it has an associated dust cloud that is obscuring stars behind. The dust cloud is one of many "dark nebulae" catalogued by Barnard and this is B168.

Last night I decided to move off of the NGC / Messier catalogs and switch over to the Index Catalog side of things, at the suggestion of a friend. His suggestion? IC 5146 also known as the Cocoon Nebula. At first I had a bit of trouble with finding it in the hand controller until someone on Facebook walked me through how to switch menus on the LX200 Classic's hand controller.
This is a combined stack of 110 light frames @ 30 seconds each, ISO1600. 30 darks and flats were also applied for calibration, plus 20 bias. I am going to shoot more of this target for more integration on it.
Also, last night, while capturing this (and later, IC 1396) I spotted one heck of a fireball. It blazed the sky in the direction of Ursa Major in a west-trending direction and lit the sky up twice the brightness of the full moon! It has been ages since I've seen a meteor light up that spectacularly!
Captured using a Nikon D5100 DSLR and a 10" Meade LX200 f/6.3 Wide Field telescope.
Unfortunately, all EXIF data is erased in the stacking process.
Recently saw this done by a few friends (John and Dave) here on flickr and thought it'd be fun to give it a try with this year winding down. To create the mosaic, I used the tool found here.

This beautiful nebula in Cygnus is a mix of emission (red) and reflection (blue) nebulae, all powered by the intensly bright star at the center.
The dark nebula leading away from the Cocoon is called B168, and is part of the same molecular cloud.
Visually, the Cocoon is a challenge, requiring large apertures. It responds well to an H-Beta filter. In dark skies, B168 is fairly easy in binoculars.

The Cocoon Nebula is an emission nebula and star cluster about 4,000 light years away in the constellation Cygnus. The nebula holds a bright red emission nebula, blue reflection nebulae and dark absorption nebulae. The massive central star formed about 100,000 years ago.
I imaged this nebula with my William Optics FLT132, F68III 1x flattener, ZWO 2600MC Pro colour camera and both the Antlia Triband RGB Ultra filter, on ZWO AM5 mount.

IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection[1]/emission[2] nebula and Caldwell object in the constellation Cygnus. IC 5146 refers specifically to the nebula and Collinder 470 to the star cluster.[3] It shines at magnitude +10.0[4]/+9.3[2]/+7.2.[5] 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.[1][4] The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago;[6] the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.[5] 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.

IC 5146 è un ammasso aperto legato ad una nebulosa diffusa visibile nella costellazione del Cigno.
Si individua 3,5 gradi ad est di M39, nella parte settentrionale della costellazione; è invisibile con un binocolo, occorre un telescopio di 150mm per apprezzare l'oggetto minimamente. È un piccolo ammasso circondato da una nebulosa molto raccolta (a forma di Bozzolo), connessa a sua volta ad un sistema di nebulosità oscure, conosciute con la sigla B 168, che si estende per circa 2 gradi in direzione di M39, evidentissima anche con piccoli strumenti in quanto oscura un ricco campo stellare. La stella principale dell'ammasso ha magnitudine 9,74 (probabilmente però appare solo in "sovraimpressione", perché la sua distanza sarebbe inferiore a quella dell'ammasso). Quest'insieme di nebulose avrebbero una distanza dal Sole pari a circa 3300 anni-luce.

Despite not-so-great transparency I set out to record the Cocoon and its surrounding stars from my driveway. The nebula on its own is a striking object, but the way that it is nestled inside a long dark nebula (Barnard 168) makes it even more interesting... it looks like the cocoon is meandering across the Milky Way, eating up stars as it goes, just like a giant cosmic Roomba.
