There are a lot of firsts for me in this image. First deep sky image from a dark sky (SQM 21.3 on this night), first image with new camera (SBIG STF-8300C), first time automating entire imaging run (via ACP), and first time combining images from multiple nights. It's also the first time I've done the majority of processing in PixInsight. So much to learn in this hobby!

This rich starfield spans almost 10 degrees across the sky toward the northern constellations Cassiopeia and Perseus. On the left, heart-shaped cosmic cloud IC 1805 and IC 1848 are popularly known as the Heart and Soul nebulae. Easy to spot on the right are star clusters NGC 869 and NGC 884 also known as h and Chi Perseii, or just the Double Cluster. Heart and Soul, with their own embedded clusters of young stars a million or so years old, are each over 200 light-years across and 6 to 7 thousand light-years away. In fact, they are part of a large, active star forming complex sprawling along the Perseus spiral arm of our Milky Way Galaxy. The Double Cluster is located at about the same distance as the Heart and Soul nebulae. Separated by only a few hundred light-years, h and Chi Perseii are physically close together, and both clusters are estimated to be about 13 million years old. Their proximity and similar stellar ages suggest both clusters are likely a product of the same star-forming region. via NASA ift.tt/2d6Gz3C

Messier 8 and 20, the Lagoon and Trifid, appear so low in the northern sky that it has been a challenge for me to image them from home, where trees impinge on my horizon. This was captured at a Westchester Amateur Astronomers' star party last week. The Lagoon is a large emission nebula formed principally from hydrogen gas; the smaller trifid is a more complex structure featuring an emission nebula (red), a reflection nebula (blue) and a dark nebula which carves the red structure into its three petaled shape. Both structures are estimated to lie some 4-6,000 light years from earth.

Really beautiful object catalogued as 881 on the Lynds' Catalogue of Dark Nebulae.
It's one of the jewels that you could find on gamma Cygni nebula, on SADR region of Cygnus, one of my favorites regions of the sky.
"A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds." (wiki)
It was necessary to integrate more than 70 hours to show all faint and nice details on the estructure.

IC 1805 (also known as the Heart Nebula) is a diffuse nebula in association with an open cluster , visible in the constellation of Cassiopeia.
It is a very large HII region , whose distance is estimated to be around 7500 light years from us; its main feature is the presence of two large apparently empty areas, of different sizes, which make the nebula similar to a "heart". Inside there is a system of small open clusters not very concentrated, responsible for the ionization of the nebula. The most notable of these is Melotte 15, which contains some stars about 50 times more massive than the Sun.

The Orion Nebula is a diffuse nebula in the constellation of Orion and is one of the brightest nebulae. It is also visible to the naked eye in the night sky. (It is the middle "star" of the handle of the saucepan.) It is located approximately 1,344 light years from Earth and is the closest region of massive star formation.
This is just a short image run of RGB only as orion didn't rise over the roof of the house next door until late in the evening. It is also probably one of the most photographed nebulae in the night sky.

Another close up into the famous deep southern sky object, Large Magellanic Cloud.
This region contains star clusters, double clusters, a super cluster, emission nebulae and a globular cluster (NGC1850, 1854, 1855, 1856, 1858) in the Dorado constellation, located in the northwest part of the bar of the Large Magellanic Cloud at a distance of 168,000 light years from the Sun... location of the imaged area is shown in the thumbnail image of the LMC.
This is an unusual cluster system because the main distribution of stars is like a globular cluster, but unlike the globular clusters of the Milky Way it is composed of young stars.
This object was imaged from a Bortle 4-5 quality sky.
Integration time was 10 hours and 35 minutes in bi-color, Hydrogen Alpha and OIII narrowband color with a C8 SCT at f6.3 with a QHY268M astronomy camera.
I don't usually get to this site this late in the year, but this was a warm night for late October. I hadn't been there at all since July 2019 due to the pandemic. It was so good to see the sky from there again! Taken during the morning of 2021-10-30, this is a stack of 17 expsoures of about 105 s each with an astrophotography modified Nikon D5100 (ISO 4000, focal length 31 mm). The camera was mounted on an omegon Mini Track LX2.
As I was setting up the shot, there were some trees at the bottom for the first few images, so I thought I would composite them in for some Earthly reference. Processing began in PixInsight, and the composite was finished in Photoshop.
The Gamma Cygni Nebula is the diffuse emission nebula at the center of Cygnus's cross.
It contains many dark nebulae in addition to the emission diffuse nebulae and the small GN 20.16.3.02 Reflection Nebula
(Wikipedia)
Kragg are massive leviathans that evolved to live in nebulae and globular clusters, feeding on the vast amounts of cosmic debris and radiation present in these densely-packed stellar formations, and using pressurized gaseous discharges from specialized orifices to maneuver through space. Upon the onset of the creature's adolescence, females of the species develop large gestation pods on their abdomens. These pods are filled with a highly volatile material that is nearly identical at the molecular level to the fuel used to power RCS thrusters on most space-faring craft. RCS fuel is an extremely valuable substance due to its complicated refining process when procured from other sources.
The presence of this rare material in Kragg bodies has led to atrocities and barbarism toward the creatures by pirates and other unfavorables seeking to exploit them.
In this case, a neural link was established to control the Kragg, making it unable to resist or escape. The pirates then mounted a command post and extraction equipment directly onto the creature's exoskeleton. Having direct control over all the Kragg's bodily systems, they can now produce as much fuel as they need and direct the creature itself to wherever they can find buyers as undesirable as themselves.
Although efforts are underway to end such inhumane practices, there is currently no official policy to protect the Kragg, allowing the exploitation of these gentle giants to continue for the foreseeable future.

The Corona Australis Molecular Cloud is a faint gaseous and dusty molecular cloud with many embedded reflection nebulae, including NGC 6729, NGC 6726–7 and IC 4812. A star-forming region of around 7000 Solar masses, the cloud contains Herbig–Haro objects (protostars) and some very young stars. About 430 light years away, it is one of the closest star-forming regions to the Solar System.

The Heart and Soul Nebulae, in the constellation of Cassiopeia covers an area of the sky over ten times as wide as the full moon, and eight times as high
Located about 6,000 light-years from Earth, the Heart and Soul nebulae form a vast star-forming complex that makes up part of the Perseus spiral arm of our Milky Way Galaxy. The nebula to the right is the Heart, designated IC 1805 and named after its resemblance to a human heart. To the left is the Soul nebula, also known as the Embryo nebula, IC 1848, or W5.
The two nebulae are both massive star-making factories, marked by giant bubbles that were blown into surrounding dust by radiation and winds from the stars.

On a clear evening in April of 1789, the renowned astronomer William Herschel continued his unrelenting survey of the night sky, hunting for new cosmic objects — and found cause to celebrate! He spotted this bright spiral galaxy, named NGC 4707, lurking in the constellation of Canes Venatici or The Hunting Dog. NGC 4707 lies roughly 22 million light-years from Earth.
NGC stands for "New General Catalogue of Nebulae and Clusters of Stars."
Over two centuries later, the NASA/ESA Hubble Space Telescope is able to "chase down" and view the same galaxy in far greater detail than Herschel could, allowing us to appreciate the intricacies and characteristics of NGC 4707 as never before. This striking image comprises observations from Hubble’s Advanced Camera for Surveys (ACS), one of a handful of high-resolution instruments currently aboard the space telescope.
Herschel himself reportedly described NGC 4707 as a “small, stellar” galaxy; while it is classified as a spiral (type Sm), its overall shape, center, and spiral arms are very loose and undefined, and its central bulge is either very small or non-existent. It instead appears as a rough sprinkling of stars and bright flashes of blue on a dark canvas.
The blue smudges seen across the frame highlight regions of recent or ongoing star formation, with newborn stars glowing in bright, intense shades of cyan and turquoise.
Iteration on the Sharpless catalogue of faint nebulae.
It's not a common object, and here is the close up. Very faint and difficult. I am really proud of it :D
Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.
The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.
This nebula is about 2/3 the diameter of the full moon.

The North American, NGC 7000, and Pelican Nebula, IC 5070, are emission nebulae in the constellation Cygnus, and lie about 1600-1800 light years away. NGC 7000 is very bright, shining at magnitude 4, but its brightness is spread out over its large size, roughly four times the size of the moon, making it quite difficult to see visibly. The Cygnus wall is prominently shown and corresponds to the Mexico/Central American region of North America. Both the Cygnus wall and the Pelican Nebula have very active regions of star formation. The rift between these two objects is caused by intervening interstellar dust that scatters the light on its way to us.

Here's the third installment of my "ice nebulae" series, a visual exploration of the ceiling of an ice cave in Iceland from a few years back. The series is named because of how the trapped volcanic dirt and dust suppressed the light behind, which reminded me of the cosmic dust that does the same stuff.
Here's number 1 and number 2 if you care to take a look at the series. Both of these are currently available for viewing at Slice of Light gallery in Santa Barbara, California. If you happen to be in the area, I'd encourage you to stop in and take a look around.
Thanks for looking!

Here we have a wider field look at M45 taken on the Rokinon 135mm rig and enhanced with the FSQ data on the core.
With this view the greater extent of the reflection nebula can be distinguished along with the dust in the immediate proximity.
Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellationOrion. 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 includes NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion B molecular cloud complex and is about 1,350 light-years distant from Earth. (C) Wikipedia
Imaged at the Turismo Astronómico, Los Coloraos complex in Gorafe using the Celestron C14 telescope and ASI 6200MM Pro camera. Filters used were UV/IR cut, Red, Green and Blue. Only two nights were available to capture this data due to poor weather conditions in December 2024. It lacks the Ha data to bring out more background details of the Hydrogen clouds but can be added at a later date.
Thank you for viewing!

The dark nebulae in this photo are part of a complex of Bok globules inside of the Rosette Nebula, NGC 2237. Bok Globules are dense opaque clouds of dust and gas, some of which are condensing under gravitational attraction to form stars and planets.
The Rosette nebula is located in the constellation of Monoceros approximately 6000 light years away.

I've been taking pictures of nebulae in the night sky for a while now. It's not easy, but the challenges are what make astrophotography so rewarding.
Sometimes, life gets in the way of this hobby. Spending a night in the backyard on a weekday isn't always practical, and I have to make sacrifices.
However, the rewards of this effort (I believe) far outweigh the pain.

The Orion, Running Man, Horsehead and Flame Nebulae and some of the smaller nebulae in a shot of the heart of the constellation Orion.
A reprocess of an image shot in November 2015. I had captured excellent data and the processed image looked good, but I knew there was a lot missing. The region imaged contains heavy dust clouds that I had somehow managed to process out of the image, showing only the nebulae. This time, I used a completely different post-processing technique that not only preserved the clouds, but also pulled out much finer detail and more vibrant colour of of the nebulae with less "posterizing" of the objects.

The Rho Ophiuchi cloud complex is a complex of interstellar clouds with different nebulae, particularly dark nebulae which is centered 1° south of the star rho Ophiuchi, which it among others extends to, of the constellation Ophiuchus. At an estimated distance of 360 lightyears away, it is one of the closest star-forming regions to the Solar System. Rho is the 17th letter of the Greek alphabet, indicating that the star rho Ophiuchi is the 17th brightest star in the constellation Ophiuchus (so not so bright). The brightest star in this picture (lower left) is Antares (a red giant which is how our own sun will eventually die). Antares is in the constellation Scorpio. This was taken with thirty, 2-minute exposures and combined in Siril and Photoshop.
The image was taken from the Lick Observatory, atop Mt. Hamilton in San Jose, CA using a Sony A7 riv mirrorless camera and a Sony 100-400 GM lens at 143 mm on a star tracking mount.
