NGC 2170 is an emission/reflection/dark nebula in the Monoceros constellation, around 2400 light years from earth.
Besides just being pleasing to look at, this area provides a perfect showcase for different types of nebulosity all in one. The blue areas are reflection nebulae, which as the name suggests means that starlight simply gets reflected there. The red areas are emission nebulae, which means that the energy in said areas is so high (caused by UV radiation from nearby stars) that it causes the gas in said areas (mostly hydrogen) to ionize and emit red/pink'ish light as a result. The dark areas are areas of dense dust concentration where neither of the two previous things is able to happen and very little light can penetrate.

The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792.[2] It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000[3] to 400,000[citation needed] years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.(src Wikipedia)
La Nébuleuse du Croissant
La nébuleuse du Croissant (NGC 6888) est une nébuleuse en émission située dans la constellation du Cygne, à environ 5 000 années-lumière2. Elle est issue des rapides vents stellaires créés par l'étoile Wolf-Rayet WR 136 (en), qui poussent la matière issue de vents plus lents éjectés par cette même étoile lorsqu'elle était plus jeune et plus petite (de type géante rouge) il y a 400 000 ans. Le front de choc engendre ce que l'on nomme une bulle de Wolf-Rayet. La nébuleuse est principalement ionisée par l'étoile centrale (photoionisation) qui a une température de surface de 70 000K3. La composition chimique de la nébuleuse montre un enrichissement en azote et carbone et un appauvrissement en oxygène.(src Wikipedia)

Esta foto fue tomada en el campo de piedra pómez, Catamarca, al amanecer. A la derecha las nebulosas de Magallanes y por arriba la trayectoria de lo que pienso era un cometa o un satélite. Digo, pienso, porque la trayectoria no es lineal… el resto de las estrellas están sin movimiento, así que ni la cámara ni el trípode se movieron…muy raro
This photo was taken from the pumice field at sunrise. On the right are the two Magellanic nebulae and above, the trajectory of what I think was a comet or a satellite. I say, I think, because the trajectory is not linear...
The Rho Ophiuchi cloud complex is a collection of instellar dust and nebulae in the Ophiuchus constellation, around 460 light years from earth.
Technically speaking, there isn't anything too majorly exciting/unique going on here. However, a few specific circumstances are leading to the colourful spectacle we're able to observe:
- The big yellow'ish area is essentially reflected/scattered starlight from the big bright star on the edge of it. The star in question is Antares, on average the 15th brightest star in the entire night sky and quite bright and easily noticeable even when looking up with the naked eye. The reason I say on average, is because the majority of the brightest stars in our sky are variable stars (meaning their brightness changes over time), so the "ranking" will differ depending on when you're looking exactly.
- The two blue/pink areas are there because of essentially the same reason. The only difference being that instead of one massive star, there's two less massive (but still quite substantial) blue stars who's light is being reflected/scattered here. The two stars in the middle of the leftmost area are called Rho Ophiuchi A and B and is where the complex as a whole gets its name from.
- The dark lanes all throughout the image are dense concentrations of dust, blocking (most) light from coming through.
- The globular cluster (circular grouping of stars) on the top right is the globular cluster M4. This is just a chance alignment (it happens to be in the same patch of sky) and is nowhere near the cloud complex (thousands of light years more distant in fact).

GUM 15 is an emission nebula in the Vela constellation, around 3000 light years from earth.
Perhaps a somewhat less familiar designation, the GUM catalog contains a total of 85 nebulae. It was put together by astronomer Colin Stanley Gum (and hence named after him).

B252 is a dark nebula in the Scorpius constellation, an unknown distance from earth.
A common misconception about these dark nebulae (in general, not specifically this one) is that they're somehow empty voids of space. There's a B68 image taken by Hubble that makes its way across social media platforms every so often where people (incorrectly) make that claim. So what are we looking at then?
These dark regions in space are every bit as populated as the regions surrounding them. The only difference is that from our vantage point; there's some thick dust clouds in the line of sight blocking our view in visual wavelengths of light (in plain English, light that our human eyes can see). When scanning said regions with specialized instruments that operate at longer wavelengths (infrared and beyond), said regions become indistinguishable from their surroundings (as far as how densely populated they are).

The Pleiades taken this week during a surprise and brief period of dark skies and no clouds.
The Pleiades or Seven Sisters, catalogued as Messier 45, is an open star cluster of middle-aged hot blue B-class stars in the constellation Taurus, approximately 444 light years from Earth. The glowing blue nebulosity is thought to be an interstellar dust cloud, illuminated by the stars.

The Horsehead and Flame Nebulae! Re-processing data from November 2019, this time with Astro Pixel Processor. This is RGB only, no filters. D810A, 600mm at f/4, ISO400, 20 minute subs, 10 subs (lots of satellites too!) CGEM II EQ mount, APT camera control, PHD2 autoguiding.
The Galactic core is above the horizon, we see the "Dark Horse nebulae" facing right the right front leg is raised, clouds of dust create the dark patterns in the Milky Way. The green sky is due to airglow similar to aurora in colour but not the same process
Located in the direction of one of our own galaxy branches, Cygnus, overpopulated with nebulae, star clusters, dark clouds of interstellar dust...a very interesting part of northern skies...
My latest astro image, an interesting region of the sky in the constellation Cassiopeia, this includes the Lobster Claw Nebula, The Bubble Nebula (NGC 7635), the open cluster M52 and the Northern Lagoon Nebula (NGC 7538)

Sharpless 101 (Sh2-101) is a H II region emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth.

This is a starless image of the Great Orion Nebula (M42) with the reflection nebula Sharpless Sh2-279 the "Running Man Nebula" situated above.
The "little" coma-shaped nebula above and separated from M42 by a dark dust lane is M43 or De Mairan's Nebula.
All form part of the sword region in the magnificent constellation of Orion.
I used Starnet to remove the attendant stars in the image and then concentrated on the nebulae in order to highlight the huge clouds of glowing gases and dusty details within this fascinating region.
M42 is an emission/reflection nebula and this huge cloud of glowing gas and dust is a great stellar nursery where new stars are being born. The pink/red glowing colour is due to the excitation of hydrogen gas and the chief visible emission line appears red to our eyes.
The Running Man Nebula above in contrast shines by reflection. It is visible to our eyes because of illumination from within by embedded stars.
Extensive dust clouds can be seen throughout the image being illuminated to varying degrees.
Imaged with a Skywatcher Esprit 120ED with focal reducer and a ZWO 2600MC camera at gain 100 and cooled to -10C.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion.[b] It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years[3][6] and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun
