One of the most identifiable nebulae in the sky, Barnard 33 or the Horsehead Nebula, is located in the constellation of Orion and lies around 1,500 light years distant. It is part of a large, dark, molecular cloud complex. The bright star to the left centre is Alnitak and the bright emission nebula behind the Horsehead is IC 434. Imaged on the night of 30th.November 2019. The luminance data used was made up from an earlier image of the Horsehead (7hrs05min acquisition time).

The Horsehead and Flame Nebulae and surrounds in Orion. This is more data added to an existing shot I had and processed a little differently. 10 minute shots, Nikon D810A, Sigma Art 135mm at f/2, ISO200, mounted to a Celestron CGEM2 EQ mount, guided by PHD2, camera and mount control with APT, stacking and integration and star reduction in APP, final edit in Photoshop. I used a few 60 second shots for a bit of HDR on the Orion nebula. I also got overlapping panels surrounding this frame with the intention of getting a bit more of a flat field for this view but these shots could not be integrated in APP for some reason, I kept getting errors after hours of processing so in the end I didn't use any of those shots at all!
The Orion Nebula can be seen with the naked eye in dark skies and is located in the belt of the Orion constellation.

Monoceros is a faint constellation on the celestial equator. Its name is Greek for unicorn. Its definition is attributed to the 17th-century Dutch cartographer Petrus Plancius.
Monoceros is home to The Rosette Nebula , the Christmas Tree Cluster and the Cone Nebula.

www.facebook.com/moonrocksastro
The Rosette Nebula (NGC 2237, 2238, 2239, and 2246) is a diffuse nebula in Monoceros. It has an overall magnitude of 6.0 and is 4900 light-years from Earth. The Rosette Nebula, over 100 light-years in diameter, has an associated star cluster and possesses many Bok globules in its dark areas. It was independently discovered in the 1880s by Lewis Swift (early 1880s) and Edward Emerson Barnard (1883) as they hunted for comets.
The Christmas Tree Cluster (NGC 2264) is another open cluster in Monoceros. Named for its resemblance to a Christmas tree, it is fairly bright at an overall magnitude of 3.9; it is 2400 light-years from Earth. The variable star S Monocerotis represents the tree's trunk, while the variable star V429 Monocerotis represents its top.[3]
The Cone Nebula (NGC 2264), associated with the Christmas Tree Cluster, is a very dim nebula that contains a dark conic structure. It appears clearly in photographs, but is very elusive in a telescope. The nebula contains several Herbig-Haro objects, which are small irregularly variable nebulae. They are associated with protostars.
Lion Nebula - Sharpless 132
The Lion Nebula, catalogued as Sharpless 132, in the constellation Cepheus, is a faint emission nebula around 10,000 ly away. It contains two ionizing Wolf Rayet stars and two dark nebulae (LDN 1150 & 1154).
My latest astro project and my first attempt at mono with my ASI294mm-Pro. Processing was done with AstroPixelProcessor and Photoshop with StarXTerminator. A total of 17h 10' of exposure time with Ha, OIII and SII 7nm ZWO filters. The colours are false using a SHO palette which maps the SII signal to red, Ha signal to green and OIII signal to blue and the colours then changed in Photoshop.

Object: NGC7000 & IC5070 or the North American and Pelican Nebulae HST - 2018
North American Nebula (NGC7000): A hydrogen and dust cloud located in the constellation Cygnus which you can see rising in the east in summer to fall. Cygnus is sometimes called the Northern Cross and has the very bright star Deneb as the head of the cross. (Deneb, Vega and Altair make up the Summer Triangle). NCG7000 vaguely resembles the outline of the North American continent.
IC5070 or the Pelican Nebula is an H II region located near the North America Nebula in the constellation of Cygnus. The gaseous clouds of this emission nebula resemble a pelican, giving rise to its name.
This photo was done using the HST or Hubble Space Telescope Palette (sometimes called SHO: SII = red, Ha= green, OII = blue) which is accomplished by combining sub frames using three narrowband filters that capture light produced by glowing hydrogen (Ha), oxygen (OIII) and sulfur (SII) present in the nebula. Green is assigned to hydrogen, blue to oxygen and red to the sulfur.
Note: this is the first photo I have done with the KAF-16200 based, Starlight Xpress SX-46, so I picked low hanging fruit! This full frame chip also allowed me to get both nebulae into the same shot without using a mosaic or a very wide angle camera lens.

In galaxy and nebulae
Mirrors the deep and lustrous
Kind of planet
Reflecting its alike twins
Already existing for trillion generations
The trillion light years beyond the universe and outer space
In galaxy and nebulae
Matters not a daytime or a night
The planets distributed the gravity without right or wrong
Flying stones, dusts and rocks drifting without gain or loss
Nebula alternating its light and dark in deep outburst
The instant birth and death of meteor’s collision
In galaxy and nebulae
Every moment is like this life
Setting forth the human in earth
The future is an unpredictable journey
Subsisting in a spacecraft with constant temperature
The heading direction beyond cold and hot
In galaxy and nebulae
Sperm and ovum combining the continuation of embryo
Youth withered in flight
Life a newborn in flight
Soaring further to a deep and gloomy milky way
The difference of love and hate gradually lost its remembrance
In galaxy and nebulae
The countless stars flashing high in universe
Dodging a farewell, separation is beyond the countless light years
Suddenly find one like the twin of earth
A new birth or a casting shadow?
The contradiction of lonesomeness and intimacy entangled in an encounter

A nebula created in May 2019 as seen from Dumbarton, Scotland.
A nebula (Latin for 'cloud' or 'fog'; pl. nebulae, nebulæ, or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, the term was used to describe any diffuse astronomical object, including galaxies beyond the Milky Way. The Andromeda Galaxy, for instance, was once referred to as the Andromeda Nebula

The Orion Nebula Messier 42, M42 is a diffuse nebula situated in the Milky Way Galaxy, south of Orion's Belt in the constellation of Orion. M42 is located 1344 light years away, and is the closest region of massive star formation to Earth.
The Running Man Nebula M43 is a popular target for amateur astrophotographers, as it lies close to the Orion Nebula and has many guide stars. The outline of the running man shows up primarily in photographs; it is difficult to perceive visually through telescope, thought the reflection nebula itself is visible in small to medium apertures in dark skies.
Additionally the sparse scattering of bright stars without nebulosity at the top of this image is NGC 1981, a compact and detached cluster.

Eastern Veil Nebula (C33)
I've recently upgraded my astro setup with a new scope (Takahashi FSQ-85EDX Baby Q) and also had several clear nights to try it out (amazing as new gear normally comes with clouds). I've also been learning AstroPixelProcessor for stacking and processing which has made a big difference to the final results.
The Eastern Veil nebula (designated parts IC1340, NGC6992 and NGC6995) is part of the larger Cygnus loop - a supernova remnant about 1500 light years away in the Cygnus (Swan) constellation and is 5000-8000 years old. The total size of the nebula is about 3 times the width of the full moon.

Two star nurseries near our galaxy's dense core. The Lagoon is 4100 light years distant, and the Triffid is further at 5200 light years.
I posted another image from this night recently, and decided to try processing another one from the bunch. I think this time the colors are much more accurate.
This was my DSLR at 400mm riding atop an 11" Schmidt Cassegrain telescope on a tracking fork mount. On a fork mount, a center star will be accurately tracked, but stars at the periphery will suffer "field rotation" with exposures longer than 30 seconds. One needs an equatorial mount to track longer, or one could stack many shorter images in post.
This was just a single exposure of 30 seconds at f5.6, iso1600.
Other (not lazy) astrophotographers would have taken many longer images and layered them, to increase the signal to noise ratio and bring out more details.

The nebula Messier 78 is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.
M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light.
