The often-photographed (certainly by me) area of the North America Nebula, NGC 7000, near the bright star Deneb, which is in the frame at right, in Cygnus. The Pelican Nebula, IC 5067/70 is right of the North America, in the “Atlantic Ocean” so to speak. The nebulosity at bottom is the “Cygnus Arc,” IC 5068. The small patch of blue reflection nebulosity at top is IC 5076. The patches of dark nebulosity above the North America Nebula are B352 and B356.

This is a stack and blend of: four exposures without a filter, each 8 minutes at ISO 800, and four exposures with an Optolong L-Enhance nebula filter to bring out the faintest nebulosity, each 16 minutes at ISO 1600. These are blended in with a Lighten mode. All were with the William Optics RedCat 51mm astrographic refractor at its native f/5 and Canon EOS Ra camera, the factory filter-modified camera capable of recording this type of hydrogen-alpha emitting nebulas. Guided with the ZWO ASIAir and ASI120MM guide camera, on the Astro-Physics Mach1 mount. Taken from home on a perfect summer night on August 15, 2020.

Another trip into space, this time to Orion that, at present, rises above the horizon late in the evening and is visible higher up in the sky from midnight onwards. The Horsehead Nebula is an iconic dark nebula in the Orion constellation. Along with the nearby Flame Nebula (to the left in the image) they are part of the much larger Orion Molecular Cloud Complex. Compared to some nebulae, this one is very easy to find - it is located near the most eastern star in Orion's Belt, Alnitak and is 1500 light years from Earth.

I was trying out some new equipment when I thought I would try Carina as it was over head. At one point I had to go inside the smoke was so strong and the Guiding got very bad. Only the Second shot I have done that was almost totally edited in PixInsight never see the amount of nebulocity around the main nebula. the mount stopped as the house next door got in the way enjoy the Southern hemisphere at 900mm. DSLR @ 600mm same scope.

Top right: the M4 Globular Cluster, s a dense sphere of stars (100,000), with an estimated age of 12.2 billion years. Located about 7,200 light-years away, it's one of the closest globular clusters to Earth. M4 is easily visible with binoculars and small telescopes, especially during the summer months. All the color? much closer. The Rho Ophiuchi cloud complex is a prominent star-forming region located about 400-460 light-years away in the constellation Ophiuchus, making it one of the closest to Earth. It's a vibrant, dynamic region composed of gas and dust, containing both bright reflection nebulae (blue light from stars scattered by dust) and darker areas where stars are being born.

The name of this one how could I resist. Has been a cloud fight to get the shots over 4 night in very strong winds. this sits just below the Horse head nebula and just off the red ring that goes around Orion.

SH2-308, commonly known as the "Dolphin Head Nebula" is a HII region located in the constellation Canis Major. It is approximately 4300light years away. he massive star that created the bubble, a Wolf-Rayet star, is the bright one near the center of the nebula. Wolf-Rayet stars have over 20 times the mass of the Sun and are thought to be in a brief, pre-supernova phase of massive star evolution. Fast winds from this Wolf-Rayet star create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of evolution.

This image was captured with a ASI 2600MC Pro OSC camera and a TS-Optics 90mm CF APO f.6 Refractor (543mm focal length). I used a optolong L-eXtreme filter to capture the narrowband data.

This was my first time shooting 1000s exposures! I think it turned out pretty great, although I only have about 4.1hrs on the target.

La Nebulosa Grotta (Sh2-155 o C9) è una splendida nebulosa a emissione situata nella costellazione di Cefeo, a circa 2400 anni luce di distanza dalla Terra.

Per questa immagine ho utilizzato filtri interferenziali dualband, che mi hanno permesso di realizzare una composizione in Hubble Palette: il rosso è assegnato allo zolfo ionizzato (S II), il verde all’idrogeno alfa (H α) e il blu all’ossigeno doppiamente ionizzato (O III).

Le pose guidate da 600 secondi sono state:

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.

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.

More formally known as Simeis 147, the spaghetti nebula is a supernova remnant in the constellation Auriga, the remains of a star which exploded around 40,000 years ago. It is a very large nebula - filling the widefield frame of my WO Redcat51 + QHY268C system - but, also very faint and this image is a total of over 23 hours exposure. This was my first use of the Optolong L-eXtreme dual narrowband filter and I am very pleased with the result. Image acquisition was controlled via Sequence Generator Pro and PHD2, all post-processing was with PixInsight.

NOTE: This image was taken under a very polluted sky ( yellow-red zone ) and with high humidity. I am very impressed about how much signal I acquired and I have to say that the L-Pro filter worked very well against the light pollution! I had to integrate a lot because of the sky which was not so good.

Very satisfied of this result!

I always want to thank Terry Hancock, who is my teacher, for explaining me how to reach a good result even if I have acquired from a polluted sky and not only - I could not have reached all my latest results without his help! Thank you, Terry!

The incandescence of the Eagle Nebula is laced with intricate dark lanes, globules, and huge clouds of dust which shroud ongoing star formation from direct view. The most prominent dark structures are the so-called “Pillars of Creation”, three long fingers of gas and dark dust nearly ten light years long. The Pillars are a field laboratory for the study of star formation and have been examined intensely by astronomers at visible, infrared, and ultraviolet wavelengths. Within the Pillars are much smaller, warmer, and denser regions called evaporating gaseous globules (EGGs), some of which contain just a few solar masses. The EGGs are ground zero for star formation, though it’s difficult to catch these new stars in the act of igniting because they remain obscured by cloaks of dark dust. EGGs located near bright stars are elongated by winds of light and charged particles into what look like schools of celestial tadpoles.

The stars within the Eagle Nebula appear to be in an intermediate state. Stars within the Pillars and other dusty regions remain obscured, while a cluster of some 400 new stars clearly appears in a more transparent section of the nebula. The largest of these stars has a mass some 80 times that of our Sun and the luminosity of perhaps a million Suns. The cluster formed just 2 to 5 million years ago. The nebula itself is only slightly older.

The light we see from the Eagle Nebula and its associated stars left some 7,000 years ago, but some astronomers suspect the Pillars of Creation may have already been obliterated when a massive young star within the nebula detonated as a supernova. The Spitzer Space Telescope detected evidence of a patch of hot gas near the Pillars which may have been caused by such an event about 8,000 years ago.

The Orion Nebula, possibly the most photographed deep sky object in the night sky. 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. 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 1350 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across and it has a mass of about 2000 times that of the Sun.

Nota anche come Sh2-240 o Nebulosa Spaghetti , è un celebre resto di supernova visibile nella costellazione del Toro, al confine con l'Auriga. La nebulosa si presenta sotto forma di delicatissimi filamenti, più densi nel lato sud-orientale e molto più rarefatta in quello occidentale; sono stati creati da un'antica supernova esplosa a circa 1470 parsec (4800 anni luce) dal Sole, sul Braccio di Perseo. Se le misure di distanza sono corrette, l'oggetto avrebbe una dimensione reale di ben 160 anni luce. La supernova sarebbe esplosa circa 40.000 anni fa, lasciando verso l'angolo meridionale dell'oggetto una pulsar; la stella che ha originato quest'oggetto probabilmente era una membro dell'associazione Auriga OB1 ed era quindi legata all'ammasso apertoM36, dal quale sarebbe sfuggito prima di terminare il suo ciclo Vitale

Eta Carina Nebula, taken with Takahashi FSQ 106 and ZWO ASI2600MC,Optolong L-Ultimate, 20x420", from Khomas region Namibia, Tivoli Southern Sky Guest Farm.

More formally known as IC 63, the Ghost nebula is a giant cloud of hydrogen gas and interstellar dust near the blue supergiant star gamma Cassiopeia - the middle star of the distinctive W asterism of the constellation. The intense radiation from gamma Cas is exciting the hydrogen gas, prompting the emission of red hydrogen alpha light, and is reflected as blue light from the dust.

This image is an integration of data shot with hydrogen alpha, red, green and blue filters with over 13 hours of Ha data and 4+ hours in each of R, G and B. The data was captured with a QHY163M CMOS camera and a William Optics FLT110 telescope. All processing of the data was carried out in PixInsight.

Observed from Prachinburi, Thailand.

The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

M13 Great Globular Cluster in Hercules

Had a few cloudless hours to grab an easy target. It is the first DSO I have imaged since November. Either my sky conditions have really deteriorated since November or there were some high thin clouds. Either way it was good to give the gear a run.

I tried something different and shot 200 Luminance filter subframes only 5 seconds each. I combined this with some RGB I shot in 2013 from my QHY23M and AT65. The large number of subframes really seemed to produce a much cleaner image. In a few months when it is clear again I will give 100+ subs a try again

Mare Crisium (Sea of Crises) is one of the Moon's great "seas", a vast impact basin that later filled with lava. It formed from a collision between the Moon and an asteroid between 4.55 and 3.66 billion years ago. Its diameter is 345 miles, roughly the distance between Bridgeport and Dauphin Island.

Mare Crisium is visible to the human eye in near the Northeastern edge of the Moon. It is prominent in photographs. In this image, it is soon to be engulfed in the lunar night.

Mare Crisium will soon be visited by small unmanned landers as part of NASA's CLPS (Commercial Lunar Payload Services) program. A contract has been awarded to Firefly Aerospace for a 2023 landing.

In the constellation of Canes Venatici but quite close to Ursa Major’s star Alkaid lies the Whirlpool Galaxy, a beautiful interacting grand-design spiral galaxy. It is located at about 31 million light years from us and can be seen during Spring even with binoculars if the sky is dark enough.

Very prominently, this galaxy is interacting with a smaller one - NGC 5195 - the yellowish one on the right. As a result, large tidal tails are formed - those are the faint yellow structures around both galaxies.

Looking closer to M51, dark lanes in the spiral arms can be seen; what are these? They are compressed gas and dust clouds - the raw material for stars. And these new stars being formed are what makes the blue patches seen nearby.

One of amateurs astrophotographers preferred targets, the Whirlpool galaxy is, for sure, an amazing view. I hope you enjoy.

The Jellyfish Nebula (IC 443, Sharpless 248) is a supernova remnant located in the constellation Gemini. It lies approximately 5000 light years from Earth and can be found between the stars Mu and Eta Geminorum, at the foot of one of the celestial Twins.

The Jellyfish Nebula is a remnant of a supernova that occurred in the Milky Way between 3000 and 30000 years ago. The supernova event produced the nebula and a neutron star. The presence of the neutron star and the nebula’s location in a star forming region indicate that the remnant was created by a Type II supernova, one triggered by a rapid collapse and violent explosion of a star with a mass at least 8 times that of the Sun. The neutron star is moving away from the site at about 800000 km/h.
