NGC 6960 a.k.a. Western Veil Nebula a.k.a. The Witch's Broom
………………………………………
10,000 years ago, long before the first records in human history, a bright light appeared in the sky and lasted for weeks until it faded and disappeared. Now we know that the phenomenon was caused by the explosion of a supernova, a huge star, 20 times larger than the Sun. What is seen in the attached image is a part of the remnants of that star, remnants that created a cloud consisting mainly of hydrogen (red) and oxygen (blue) and which expands with a speed of about 1 milion miles per hour.
This nebula is found in the constellation Cygnus, at a distance of about 2400 light-years from Earth, and is one of the best known summer targets for astrophotography enthusiasts, but due to the large number of stars in that area, it cannot be considered a easy target.
Besides Witch's Broom, other names under which this nebula is known are: Finger of God, Filamentary Nebula or Lacework Nebula.

After a long break from doing astrophotography, I decided to spend some time last night and use the new gear I recently got shooting a popular and relatively easy target, The Pleiades. It does appear the lens was slightly off on focus, but whatever. Most people will never pixel-peep it anyways. It all worked great, and it felt good to capture the heavens again.

I polar aligned my mount using SharpCap Pro. 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. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file and used Gradient XT on the image. I then made it a 16-bit file and stretched it in levels, then curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset and relied on Astronomy Tools Action Set and Topaz Denoise and Sharpening to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.

The Cygnus Wall is a ridge of intense star formation within the North America Nebula (NGC 7000), located approximately 1,500 to 2,600 light-years away in the constellation Cygnus. Its key facts include its location, size (about 20 light-years across), composition (gas, dust, and newly forming stars), and the role of nearby young stars in ionizing the gas, which causes it to glow red.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus, at about 2400 light years from us.
It constitutes the visible portions of the Cygnus Loop,a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. In modern usage, the names Veil Nebula, Cirrus Nebula, and Filamentary Nebula generally refer to all the visible structure of the remnant, or even to the entire loop itself. The structure is so large that several NGC numbers were assigned to various arcs of the nebula. There are three main visual components: 1. The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", Lacework Nebula, "Filamentary Nebula"; 2. The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula"; 3. Pickering's Triangle (or Pickering's Triangular Wisp), brightest at the north central edge of the loop, but visible in photographs continuing toward the central area of the loop.
The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. The remnants have since expanded to cover an area of the sky roughly 36 times the area of the full Moon.

I clearly need more data for this one, but this is part of my learning curve for shooting through the Celestron Edge HD 925 with the Nikon D5100. I used a light pollution filter and was shooting at ISO 1600. This is a stack of 30 exposures that were around 55 s in length at a focal length of 2200 mm. I reduced the size of the final image substantially because it was so noisy.
Preprocessing, registration, stacking, and initial processing were done in PixInsight; final touches in Photoshop.
The Crab Nebula (catalogue designations M1, NGC 1952) is a supernova remnant in the constellation of Taurus, it was first identified in 1731 by English astronomer John Bevis. The nebula was independently rediscovered in 1758 by Charles Messier as he was observing a bright comet. Messier catalogued it as the first entry in his catalogue of comet-like objects.
After some observation, noticing that the object that he was observing was not moving across the sky, Messier concluded that the object was not a comet. Messier then realized the usefulness of compiling a catalogue of celestial objects of a cloudy nature, but fixed in the sky, to avoid incorrectly cataloguing them as comets.
William Parsons, 3rd Earl of Rosse observed the nebula at Birr Castle in 1844 using a 36-inch (0.9m) telescope, and referred the nebula as the "Crab Nebula" because a drawing he made of it looked somewhat like a crab. He observed it again later, in 1848 using a 72-inch (1.8m) telescope and could not confirm the supposed resemblance, but the name stuck nevertheless.

I finally got the chance for a few nights this month on this wonderful target: A beautiful, if faint, emission nebula between Cepheus and Lacerta and probably my favourite nebula to date - The very small planetary nebula (bottom left) is Abell 79. Abell 79, "The 6 Nebula", is estimated to be at a distance of 5900 to 11,360 lys away. It measures approx 1 arc minute and is magnitude 15. Sh2-132 lies at an estimated distance of about 10,000-12,000 lys and is ca. 40 arc minutes in size. The image also contains the very small planetary nebula G101.5-00.6, which lies to the right of the blue O-III region.

My project for February 2026 - Melotte 15 is a young open star cluster located at the very center of the Heart Nebula (IC 1805), approximately 7,500 light-years from Earth in the constellation Cassiopeia, nestled in the Perseus Arm of the Milky Way galaxy.
One of the most famous features of Melotte 15 is the presence of towering pillars of gas and dust. These look like dark, jagged silhouettes against the glowing background. Often called the "Heart of the Heart," this cluster is the primary engine driving the nebula's brilliant glow and complex structure.
It is easy to see why Melotte 15 captures the imagination of astronomers and astrophotographers alike. It’s a perfect example of a "stellar nursery" where the newborns are already reshaping their home. While the Heart Nebula spans nearly 200 light-years, its energy source is concentrated in Melotte 15. The cluster contains several massive O-type stars, which are among the hottest and most luminous stars in the universe.

Messier 104 a.k.a. Sombrero Galaxy
…………………………..
Discovered 250 years ago, the Sombrero galaxy (The Hat) is an elliptical galaxy located just over 30 million light-years from us and can be seen between the constellation Virgo and the constellation Corvus. According to measurements made by specialists in the field, M104 has a diameter of about 40,000 light-years, being about 3 times smaller than our galaxy. The name of the Hat is given both by the angle from which we can see it, and due to that prominent ring of cosmic dust that surrounds this galaxy and which is also the main source of new star formation. Regarding the nucleus of this galaxy, with the help of special infrared measurements it was found that in the galactic center of M104 there is a massive black hole, larger than in any other galaxy located within a radius of 40 million light years around the Milky Way.

I was/am so pleased with how my de-bayered SIGMA fp has performed that I couldn't resist going for a de-bayered SIGMA fp L (61MP). I finally go the chance to try it out in November, having managed to chase down a small hole in the clouds in northern Italy. The conditions were hard: The wind-side of the car was covered with ice before I had finished the set-up, so that I run out of juice before I could get all the data I wanted, nevertheless im still really pleased with the result. There is some really nice "smoking gun" effects in the S-II data that I wasn't aware of before (and didn't see in the 5 minute subs) so I will definitely be looking for an off-center composition next time i'm out ...

Nella costellazione del Cefeo si trova l'ammasso aperto IC1396 circondato da una nebulosa ad emissione che fa parte di un'ampio sistema di nubi molecolari HII. Spicca la nebulosa oscura vdB 142 chiamata Proboscide d'elefante.

In the constellation Cepheus lies the open cluster IC1396, surrounded by an emission nebula that is part of a large system of HII molecular clouds. The dark nebula vdB 142, known as the Elephant's Trunk, stands out.
I combined images taken with different filters and tried merging them. I found the result pleasing and the information more complete than the individual images. 10-minute exposures were taken for each filter: 114 with the broadband SV260 filter, 61 with the dualband Antlia ALP-T 5nm (Ha and O3), and 16 with the dualband L-Synergy Optolong 7nm (S2 and O3).
To capture the stars, about an hour of integration was added in 60-second exposures with the broadband SV260 filter.
The whole thing was captured with a 150/600 Newtonian telescope equipped with a Tecnosky 0.95x corrector, a Tecnosky Vision 571C camera and an EQ6-R Pro mount, processed in PixInsight.

NGC 4565 a.k.a. Needle Galaxy
.....................................................
NGC 4565, better known as the Needle Galaxy, is a spiral galaxy located in the constellation Coma Berenice, at about 40 million light-years from Earth. This galaxy is larger than the Milky Way, with a diameter of 130-150000 light-years, and appears to be brighter than Andromeda. Due to its shape, in addition to Needle, NGC4565 is also known as Flying Saucer Galaxy or Berenice's Hair Clip. Very well known and popular in astrophotography, Needle Galaxy can be imaged with a small telescope, but a longer focal length would lead to a more detailed result.

67 scatti con filtro Antlia ALP-T 5 nm, per H α e O III;
87 scatti con filtro Optolong L-Synergy 7nm, per S II e O III.
Per le stelle, 1 ora di integrazione in pose da 60 secondi con filtro broadband SV260.
Strumentazione utilizzata:
Telescopio Newton 150/600 con correttore Tecnosky 0.95×
Camera Tecnosky Vision 571C
Montatura Sky-Watcher EQ6-R Pro
Elaborazione in PixInsight

The Cave Nebula (Sh2-155 or C9) is a splendid emission nebula located in the constellation Cepheus, about 2,400 light-years away from Earth.
For this image, I used dual-band interference filters, which allowed me to create a composition in the Hubble Palette: red is assigned to ionized sulfur (S II), green to alpha hydrogen (H α), and blue to doubly ionized oxygen (O III).
The 600-second guided exposures were:
67 shots with the Antlia ALP-T 5 nm filter, for H α and O III;
87 shots with the Optolong L-Synergy 7 nm filter, for S II and O III.
For the stars, 1 hour of integration in 60-second exposures with the SV260 broadband filter.
Equipment used:
150/600 Newtonian telescope with Tecnosky 0.95× corrector
Tecnosky Vision 571C camera

It's perhaps the most obvious deep-sky object to photograph, so it was high time I had a go. With a meeting looming last Friday evening, I set up the StarAdventurer tracker in the back garden and Sony camera firing 30s subs every 2mins. By the time I returned, the clouds had rolled in but I got 55mins of light data to be working on.
