Cygnus Wall.
.....................
Cygnus Wall is the most visible and interesting part of the well-known North America nebula, located 1500 light-years from us, in the constellation Cygnus. The "wall" is actually an area of stellar dust combined with hydrogen ionized by the radiation of young stars and stretches over a length of about 20 light-years, thus being one of the largest and best known stellar "nurseries".

Second image in my short Moon series...
This is January's full moon, captured on the evening of the 13th, 2025. I used my 200-500mm Nikkor lens and shot it handheld at 1/125th of a second.
For added artistic flare and to give the image more depth, I overlayed a Deep Space filter/layer.
Now reach up and touch the moon, traveling into the stars above!
The Spaghetti Nebula is located in the constellations of Auriga and Taurus within the Milky Way and is a supernova remnant from an exploding star. These extremely faint and fine filaments of ionised hydrogen, sulphur and oxygen are all that remains from the explosion approximately 40,000 years ago. It's distance from our solar system is estimated to be 3000 light-years.
The size of the nebula is extremely large, approximately 3 degrees, and using my small 81mm telescope, the image almost entirely fills a full frame camera sensor. To capture this image I used over 28 hours of images using 3 narrow band filters for each gas.

Dusty Subaru?
I don’t see a dusty old hatchback with bumper stickers floating in space, do you?
Of course not, Subaru is what the Japanese call the Pleiades. It means coming together or clustering, which is exactly what this star cluster is all about.
And all the left over dust from the formation of the stars is still floating around, being blown about by the stellar winds.
I was pleased to see that even with my crappy star tracker and vintage 300mm lens I could bring out all the dark dirt that is drifting around that open group of stars.
Big thanks to Siril, the astro photography software that I’m still getting to know.
Dust, the bane of my mother’s existence! As a fifties house wife she was obsessed with banishing it from our home. I hope she’s resting in peace now, and not floating around with a cosmic Swiffer trying to clean it up. Because as astro photographers we love dust, especially when it is illuminated, right?

SH-2 132 Lion Nebula HOO
SH2-132 Lion Nebula has always been an image I wanted to capture and actually look a little like a Lion.
Not sure if it made the grade this time but pleased with the colour contrast and details in the Oiii and Ha regions.
In this image I made some changes to the editing workflow to leave the colour control and blending to PhotoShop and used PixInsight for the image pre-processing and stacking.

Messier 3 (M3 or NGC 5272) is a globular cluster of stars in the northern constellation of Canes Venatici. It was discovered by Charles Messier on May 3, 1764, and resolved into stars by William Herschel around 1784.
This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is estimated to be 8 billion years old. It is located at a distance of about 33,900 light-years away from Earth.
A globular cluster is a spherical collection of stars that orbits a galactic core as as satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centres.

Markarian's Chain is a stretch of galaxies that forms part of the larger Virgo Custer in the constellation of Virgo. The two bright galaxies on the lower section of the chain are M84 and M86 discovered by Charles Messier in 1781. In this field of view approximately 30 identified galaxies are visible making it a spectacular target to image.

This is a mosaic made up of three panels with an integration of around 35 to 45 hours of exposure.
Caldwell 31, a huge, sprawling nebula spanning five light years and surrounding the ‘Flaming Star’, AE Aurigae, the bright star visible in the upper portion of the nebula. AE Aur (mag. +6) is an runaway star that is thought to have been one of three stars ejected from near the Trapezium in Orion 2.7 million years ago. It’s a class-O hydrogen fusing dwarf that is at least 30,000 times more luminous than our Sun. The nebula and the star lie around 1500 light years away.
The smaller nebula at the top is IC405, commonly known as the Tadpole Nebula for the small ‘tadpole-like’ structures of dense, cooler gas that are being shaped by the intense radiation from the hot stars of the young open cluster NGC 1893, embedded in the nebulosity. It’s just possible to see the tadpoles to the upper right of the largest dark section at the centre of the nebulosity, with the open cluster just above. IC405 lies 12,000 light years away.

The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.
Sadr itself has approximately a magnitude of 2.2. The nebulous regions around the region are also fairly bright.
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. 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 to 400,000 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.
It is a rather faint object located about 2 degrees SW of Sadr. For most telescopes it requires a UHC or OIII filter to see. Under favorable circumstances a telescope as small as 8 cm (with filter) can see its nebulosity. Larger telescopes (20 cm or more) reveal the crescent or a Euro sign shape which makes some to call it the "Euro sign nebula".

Rho Ophiuchi Cloud Complex
........................................................
Located at about 500 light-years from Earth, Rho Ophiuchi is undoubtedly one of the most spectacular and colorful parts of the night sky.
Emission nebulae, reflection nebulae, dark nebulae or star clusters, all can be found in this small part of the sky. There is also a star nursery, practically the closest to Earth, and not to forget Antares (in the yellow area of the attached photo), a giant star, 700 times larger than the Sun, and 10,000 times brighter.
A book could be written about this area, so I will stop here with the description. I hope I will be lucky enough to repeat the experience at the next new moon.

My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. I polar aligned my mount using SharpCap Pro. I struggled with getting guiding going and decided to trust my mount to track accurately. I took 4 121-second exposures and dark, flat, and bias frames. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file using Levels. I then made it a 16-bit file and continued to stretch the file in levels and curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset, including some dodging & burning, and relied on Astronomy Tools Action Set and Topaz Denoise to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data. I did not attempt to account for the comet's movement, and you can see the nucleus is elongated.
I have been waiting for the perfect conditions to take my first deep-space image of the Orion Nebula, and when it happened, the timing overlapped with the Geminid Meteor Shower. The odds of capturing a meteor in the shot are rare, but what was truly shocking was watching a non-geminid meteor (orange streak) that was a brighter fireball and it broke up right on the edge of my shot. Amazing experience to see and capture.
I was standing with another skywatcher at the time the brighter one broke into 2 pieces as it burned up in the atmosphere. As soon as it happened he said, "That is where you are shooting!" I just responded with, "I am too scared to see if I actually got it." When I finally got the nerve, I was absolutely stunned.
Image taken at Lake Hudson Recreational Area in Lenawee County Michigan. The Geminid Meteor was at 10:40pm on December 13th, the non-Geminid meteor was at 11:29pm. I was shooting the Orion Nebula from about 10:30pm till midnight.

NGC 7822
....................................................
This is an emission nebula located in the constellation Cepheus, about 3000 light-years from us, being a region where new stars are born. If the strong radiation emitted by the new stars ionizes the surrounding gas and illuminates the entire area, the same radiation erodes those "pillars" of cosmic dust causing, over time, those concentrated areas of dust to disappear and thus destroy the main "material" that forms the new stars.

EXOPLANETS
==================================================
Confirmed 3439
Candidates 4696
Solar systems 2569
Earths 348
Data from NASA (exoplanets.nasa.gov/)
==================================================
"An exoplanet or extrasolar planet is a planet that orbits a star other than the Sun. Starting in 1988, and as of 1 January 2017, there have been 3,557 exoplanets in 2,668 planetary systems and 601 multiple planetary systems confirmed. HARPS (since 2004) has discovered about a hundred exoplanets while the Kepler space telescope (since 2009) has found more than two thousand. Kepler has also detected a few thousand candidate planets, of which about 11% may be false positives. On average, there is at least one planet per star, with a percentage having multiple planets. About 1 in 5 Sun-like stars [a] have an "Earth-sized" [b] planet in the habitable zone. [c] Assuming there are 200 billion stars in the Milky Way, [d] one can hypothesize that there are 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if planets orbiting the numerous red dwarfs are included.
Besides exoplanets, there are also rogue planets, which do not orbit any star and which tend to be considered separately, especially if they are gas giants, in which case they are often counted, like WISE 0855−0714, as sub-brown dwarfs. The rogue planets in the Milky Way possibly number in the billions (or more)." (Text credits: Wikipedia).

About 10,000 years ago, a star exploded and died here. The Helix Nebula, also known as the Helix or NGC 7293, is a large planetary nebula in the constellation Aquarius.
Karl Ludwig Harding, probably discovered it before 1824 and it is one of the closest objects to Earth among the planetary nebulae, about 700 light years from our Earth. Sixteen hours of exposure from El Sauce Observatory in Chile (TelescopeLive) and image processing with my interpretation of 178 raw images in PixInsight and PhotoShop.

M 81 Also known as Bodes Nebula is a spiral galaxy located in Ursa Major. It is a close neighbour to M82 Cigar Galaxy in the same constellation.
M 81 was first discovered by Johann Elert Bode, who found it, along with M 82, in 1774.
M 81 is approximately 12 million light years from our galaxy and spans almost 70,000 light years.
A few hundred million years ago, a close encounter took place between M 81 and M 82, during which M 82 was dramatically deformed.
Imaged over 5 nights from my home in Gérgal, Spain.

Explanation: A bright spiral galaxy of the northern sky, Messier 63 is about 25 million light-years distant in the loyal constellation Canes Venatici. Also cataloged as NGC 5055, the majestic island universe is nearly 100,000 light-years across, about the size of our own Milky Way. Known by the popular moniker, The Sunflower Galaxy, M63 sports a bright yellowish core and sweeping blue spiral arms, streaked with cosmic dust lanes and dotted with pink star forming regions. This deep exposure also reveals an enormous but dim arc extending far into the halo above the brighter galactic plane. A collaboration of professional and amateur astronomers has shown the arc to be consistent with the stellar stream from a smaller satellite galaxy, tidally disrupted as it merged with M63 during the last 5 billion years. Their discovery is part of an increasing body of evidence that the growth of large spirals by cannibalizing smaller galaxies is commonplace in the nearby Universe.

To be honest this is more my son Matthew's hobby than mine but I must admit the results are quite surprising even though lacking a little in resolution!
I have been waiting and waiting since November to have a clear night with no wind or moonlight on a weekend. Finally, I got my chance in late March, and it was my last shot until next November as Orion will start to fade below the horizon in April.
Orion is one of my favorite deep space objects to photograph, but the bright core makes it a challenge to capture well. I really like how this turned out!
