Sh2-155 was first noted as a galactic emission nebula in 1959 in the extended second edition of the Sharpless catalogue.
The name "Cave Nebula" was coined for this object by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth.
Sh2-155 is a diffuse nebula in the constellation Cepheus, approximately 2,400 light-years away from Earth.

The Rho Ophiuchi cloud complex is one of my favorite spring targets. Not only is the region extremely colorful, it also consists of many interesting astronomical objects:
- Rho Ophiuchi is the star within the blue reflection nebula. If you zoom into the image you can see that it is actually a 3-star system. The blue color of the nebula is produced by Rayleigh Scattering, the same process that colors our daylight sky blue.
- The Rho Ophiuchi cloud complex on the other hand is the dark nebula south of the star Rho Ophiuchi. At a distance of 427 light-years, it is one of the closest star forming regions to the solar system.
- The yellow star within the yellow nebula is Antares, the brightest star of the constellation Scorpius. It is a red supergiant, nearing the end of its live. The star has depleted the fuel supply of hydrogen within its core and is now bloated to monstrous proportions. As it goes through its death throes, the star has expelled a lot of its mass as shells of gas and dust into space. The nebulosity surrounding Antares is created by this gas and dust which is reflecting the dying star’s yellowish light.
- To the right of Antares is the globular cluster M4. Globular clusters are massive, tightly packed spheres that contain thousands, or even hundreds of thousands, of individual stars.
- Above M4 you find Sigma Scorpii. It is multiple star system of hot, young stars, emitting of UV radiation. As this high energy UV light hits the hydrogen atoms it energizes them, and the electrons separate from the atomic nucleus. When they recombine, the electrons give off a reddish-pink light which makes the gas cloud glow.
- Below Antares is Tau Scorpii, surrounded by another faint emission nebula of energized hydrogen.
- Both Sigma and Tau Scorpii share the same name: Al Niyat. They got their name from ancient Arabic astronomers and it means, "the arteries". Seeing how these stars with their red nebula flank Antares, the heart of Scorpius, it makes sense that they could be viewed as the arteries of that colossal, dying heart.
As you can see, the region around Rho Ophiuchi has it all. Its colors tell a story of darkness and light, of peaceful coexistence and violence and of birth and death.

The Horsehead Nebula (also known as Barnard 33 and IC434 ) is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. It is located approximately 1500 light years from earth.
This is a two pane mosaic of the Horsehead area in Orion. I originally did the lower pane (the image below) but felt that a pane above this would give a sense of completeness in the image.
This is the first image that has taken advantage of the dual rig that I have got together.

Il 12/09/2015 acquisivo questo FOV con lo scopo di riuscire ad evidenziare anche le Nubi Molecolari che circondano il famosissimo ammasso aperto delle Pleiadi (M45). In questi casi occorrono cieli molto bui, una congrua integrazione e temperatura ambiente abbastanza bassa per chi utilizza le DSLR. Purtroppo velature e nubi mi avevano permesso di acquisire solo 14 frames da 300s: troppo poca l'integrazione di 1h e 10 min per pretendere qualcosa. Inoltre occorre ricordare che lo strumento fotografico era il teleobiettivo Zenit Jupiter-11A 135mm f4 (diametro obiettivo di 33,75 mm). flic.kr/p/MekcC7
Speravo in altre sessioni fotografiche per aumentare almeno l'integrazione totale, ma non sono stato fortunato.
Dopo un anno di inutile speranze ero comunque molto curioso di vedere cosa avrei potuto estrapolare da quei pochi frames. I frames combinati dal programma DeepSkyStacker (DSS) hanno creato il file.tif finale combinato, che mostrava appena un pò di nebulosità attorno a M45.
Il mio obiettivo erano le debolissime Nubi Molecolari quindi mi aspettava una elaborazione molto ardua!
E' stato necessario agire molto sulla regolazione livelli di PS e il forte "stretch" ha ovviamente evidenziato i limiti della poca integrazione. Non è stato facile controllare i diametri stellari e il rumore nei mezzitoni e nelle ombre . Questi effetti collaterali mi hanno costretto a lavorare molto con le selezioni e algoritmi riduci-rumore. Sapevo già che non potevo pretendere grande definizione dei dettagli.
Malgrado tutto l'obiettivo è stato raggiunto e mi ritengo molto soddisfatto del risultato finale, dove le debolissime Nubi Molecolari, presenti nella nostra Via Lattea, sono visibili.
Curiosità> Fa un certo effetto ripensare che fino a 15 anni fa con la fotografia analogica un risultato come questo era impensabile e irragiungibile con modesti strumenti.

On 09/12/2015 I acquired this FOV for the purpose too to be able to reveal the molecular clouds that surround the famous Pleiades open cluster (M45). In these cases it takes a long dark skies, a fair share integration and low enough ambient temperature for those who use DSLR. Unfortunately, clouds had allowed me to acquire only 14 frames of 300s: too little integration of 1h and 10 min to demand something. It is noted that the photographic instrument was the telephoto Zenit Jupiter-11A 135mm f4 (objective diameter of 33.75 mm). flic.kr/p/MekcC7
I was hoping for more photo sessions to increase at least the total integration, but I was not lucky.
After a year of futile hope I was however very curious to see what I could extrapolate from those few frames. The frames combined by DeepSkyStacker (DSS) program have created the final file.tif combined, which showed only a little nebulosity around M45.
My objective was very faint Molecular Clouds therefore waited for me a very arduous processing!
It was important to act on the adjustment levels of PS and the strong stretch has obviously revealed the limitations of little integration. It was not easy to control the stellar diameters and noise in the midtones and shadows. These adverse effects have forced me to work a lot with the selections and reduce noise algorithms. I already knew that I could not expect great detail definition.
Despite all, the purpose has been achieved and I am very pleased with the final result, where the faint Molecular Clouds, present in our Milky Way, are visible.
Curiosity> Makes a certain effect rethink that until 15 years ago with analog photography a result like this was unthinkable and unattainable with modest instruments.

Simeis 147, a supernova remnant also known as Sharpless 2-240, is an object typically photographed with narrowband filters, because under visible light it just appears too "poor" in comparison, mainly due to the fact that this object is extremely faint when imaged through RGB filters - and not too bright when using narrowband filters either! Narrowband data however deprives us from viewing the many other things happening around it.
Most narrowband+broadband compositions I've seen (usually H-Alpha + RGB or H-Alpha + LRGB) haven't been able to "fix" that, so I decided to give it a try, also expanding the typical already-wide FOV, to hopefully capture and visually document more of what's around.

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.
On this night the skies were beautifully clear and I was able to capture the data to create this image of Centaurus A (aka NGC5128 or 'The Hamburger Galaxy').
This is one of the closest radio galaxies to earth and is the fifth-brightest in the sky thanks to the supermassive black hole at the centre. This black hole has an estimated mass of around 55 million solar masses and ejects cosmic rays from it's core which can be captured in images taken at different wavelengths.

The Rosette nebula is one of my favorite targets. The shape and detail make it one of the most interesting deep sky objects in the northern hemisphere. Located in the constellation Monoceros, it also contain the open cluster NGC 2244. This cluster provides the solar radiation that is exciting the surrounding gas and causing the striking glow.

The Helix Nebula is a planetary nebula formed by an intermediate to low-mass star. When a star of this size ages, it gradually sheds its outer layer, making an outward-drifting shell of gas and dust. Its core collapses to form a compact white dwarf that slowly radiates its energy away. The radiation then catches up with the gases, ionizing them and creating this astonishing scene. You can find the white dwarf star in the centre of this image; it's now about the size of the Earth.
Another interesting thing about this nebula is that the star that formed it is similar to our sun. This led to the belief that in 5 billion years, when our solar system begins to age and fade away, it might turn into a beautiful nebula just like this one.
(The data was acquired from iTelescope, which I processed using pixinsight and photoshop).
Every time you change the space around you, it's worth remembering that this can lead to global changes! And our most insignificant actions can lead to very significant changes! Sometimes even a glance at a spider web in the forest can lead to changes all over the planet ;)

Accanto alla grande e luminosa nebulosa Laguna (M8), nella costellazione del Sagittario, si trova questa bella zona con la sigla "Sh2-29", chiamata Nebulosa Drago Cinese, catalogata anche come IC4685, per la singolare presenza della scia filamentosa oscura che dalla nebulosa ad emissione e riflessione "NGC6559" sembra dirigersi verso la stelle azzurra al centro.
Tutto il campo inquadrato che fa parte del complesso nebulare di cui fa parte la nebulosa M8 a 5000 a.l. dalla Terra, è ricco di nebulose ad emissione HII e riflessione nonchè nebulose ricche di OIII e nebulosità oscure che si intrecciano tra esse e che aiutano a dare profondità all'immagine. Alcune sigle sono Sh2-29, IC1275, LDN211, Collinder367, B302 e B303.

Next to the large and bright Lagoon Nebula (M8), in the constellation of Sagittarius, lies this beautiful area designated "Sh2-29", called the Chinese Dragon Nebula, also cataloged as IC4685, due to the singular presence of the dark filamentary trail that appears to be heading from the emission and reflection nebula "NGC6559" toward the blue star at the center.
The entire field of view, which is part of the nebular complex that includes the M8 nebula, 5000 light years from Earth, is rich in HII emission and reflection nebulae, as well as OIII-rich nebulae and dark nebulosities that intertwine with each other and help give depth to the image. Some acronyms are Sh2-29, IC1275, LDN211, Collinder367, B302 and B303.

NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called SH2-86. The whole area of nebulosity is often referred to as NGC 6820. Open star cluster NGC 6823 is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars.

When Atlas was punished to bear the heavens on his shoulders, his seven daughters with Pleione - Asterope, Electra, Merope, Maia, Celaeno, Taygeta, and Alcyone – started to be pursued by the hunter Orion, who had fell in love with them and their mother. In pity of their suffering, Zeus first turned them into doves and then into stars, to protect them from the Orion’s advances who, it is said, still pursues them across the sky.
Known from, at least, the Bronze Age, the Pleiades star cluster an hallmark and leitmotiv for mythologies across several civilizations and they were/are also known as Soraya (old Persia) or Subaru (Japan).
The Pleiades is an open cluster with about 1,000 stars at about 440 light years but only the brightest are visible at naked eye, even in light polluted skies; but in a dark sky and viewed through binoculars it is a truly amazing sight. They will be gravitationally bound for another 250 million and by then it will disperse in Orion’s constellation.

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.
Ho combinato riprese effettuate con filtri differenti e ho provato a fonderle insieme, ho trovato il risultato gradevole e le informazioni maggiormente complete rispetto alle sigole riprese. Esposizioni da 10 minuti per ciascun filtro, 114 con il filtro broadband SV260, 61 con il dualband Antlia ALP-T 5 nm (Ha e O3) e 16 con il L-Synergy Optolong dualband 7nm (S2 e O3).
Per catturare le stelle è stata aggiunta circa un’ora di integrazione in pose da 60 secondi con filtro broadband SV260.
Il tutto è stato ripreso con un telescopio Newton 150/600 dotato di correttore Tecnosky 0.95x, camera Tecnosky Vision 571C e montatura EQ6-R Pro, elaborazione in PixInsight.
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.
Prospetticamente attorno ad una delle più luminose stelle del cielo, la stella multipla e variabile Gamma Cassiopeiae (γ Cas), chiamata Tsih o Navi, si trova la regione di H II (idrogeno ionizzato) conosciuta con la sigla Sh2-185, e al cui interno spiccano due nebulose catalogate con le sigle IC59 e IC63.
Pensavo che riuscire a fotografare questa regione fosse una cosa più semplice invece devo ammettere che la nebulosità più debole di Sh2-185 è veramente molto evanescente e la presenza di gradienti causati da Inquinamento luminoso ha complicato le cose; quindi sono stato costretto mio malgrado ad utilizzare con decisione i tool di denoise per ridurre il rumore.
Ma ciò che ha reso più difficile elaborare questa immagine è stata la presenza della luminosa Gamma Cassiopeiae il cui riverbero abbagliava una parte dell'immagine e attorno alla quale c'era un antiestetico alone penso causato da riflessioni all'interno del riduttore 0.6X.
Ciò malgrado penso di aver raggiunto un discreto risultato.
________
Perspectively surrounding one of the brightest stars in the sky, the multiple variable star Gamma Cassiopeiae (γ Cas), called Tsih or Navi, lies the H II (ionized hydrogen) region known by the acronym Sh2-185, within which stand out two nebulae cataloged as IC59 and IC63.
I thought photographing this region would be easier, but I have to admit that the faintest nebulosity of Sh2-185 is truly very evanescent, and the presence of gradients caused by light pollution complicated matters; so, against my will, I was forced to vigorously use denoising tools to reduce the noise.
But what made processing this image more difficult was the presence of the bright Gamma Cassiopeiae, whose glare dazzled part of the image and which had an unsightly halo around it, I think caused by reflections within the 0.6X reducer.
Even so, I think I achieved a decent result.

After listening to another lecture on quantum physics, I realized that I hadn't spent much time in this area... We will make up for it ! ;)
Cari amici, non immaginavo che questa nebulosa fosse così ostica. Si tratta della nebulosa Leone catalogata con le sigle "Sh2-132" o "LBN 473" , una vasta nebulosa ad emissione nella costellazione del Cefeo. Caratterizzata dalle presenza di HII e OIII, da alcune nebulose oscure e da due "stelle di Wolf-Rayet" che ionizzano la nebulosa stessa. . E' presente in questa immagine anche "RWCephei", una stella ipergigante rossa: una delle stelle più grandi e massicce conosciute.
Durante l'acquisizione a gain 121 ho notato quanto debole fossero alcune parti della nebulosa, quindi ho dedicato una sessione a gain 250, con la speranza di migliorare. Speravo in qualcosa di meglio, ma dovevo pur accettare i compromessi causati dall'Inquinamento Luminoso, dal seeing non favorevole e dal filtro mltibanda stretta L'Enhance, che secondo me ha un'ottima risposta all'Ha ma non all'OIII ( OIII che è solitamente più debole dell'Ha che, a sua volta, lo sovrasta e soffoca). Ho cercato di utilizzare gli strumenti idonei che mi permette di usare l'app SIRIL e con lo script NarrowbandNormalization sono riuscito ad evidenziare l'OIII. Successivamente con i livelli e maschere di PS ho cercato di trovare un giusto equilibrio cromatico globale. Spero di esserci riuscito.
___________________________
Dear friends,I didn't imagine this nebula would be so challenging. It's the Leo Nebula, cataloged as "Sh2-132" or "LBN 473", a vast emission nebula in the constellation Cepheus. Characterized by the presence of HII and OIII nebulae, some dark nebulae, and two "Wolf-Rayet stars" that ionize the nebula itself. Also present in this image is "RWCephei", a red hypergiant star: one of the largest and most massive stars known.
While acquiring at 121 gain, I noticed how faint some parts of the nebula were, so I dedicated a session to 250 gain, hoping to improve. I was hoping for something better, but I had to accept the compromises caused by light pollution, poor seeing, and the L'Enhance narrowband filter, which in my opinion has an excellent response to Ha but not to OIII (OIII is usually fainter than Ha, which, in turn, overwhelms and suffocates it). I tried to use the appropriate tools that the SIRIL app allows me, and with the NarrowbandNormalization script, I managed to highlight the OIII. Subsequently, using PS's levels and masks, I tried to find the right overall color balance. I hope I succeeded.

I hope you are not fed up with Rho Ophiuchi shots yet. As spring is Rho time, I cannot guarantee that there will not be more coming...
I captured this image in the Toggenburg Valley of eastern Switzerland from the same area as my "Rural Idyll" post. Those who have seen that image may recognize the teeth as two of the Churfirsten peaks. These rocky twins are called Schibenstoll and Zuestoll and are up to on meter of the same hight (2234 and 2235 meter).

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.

IC443 (Sh2-248) a supernova remnant (SNR)is located in the constellation of Gemini. It is commonly known as the “Jellyfish Nebula”due to it's shape.
These types of objects are created by one of the most important processes in the universe - a supernova event - when a star explodes and scatters the heavier chemical elements it has made during its lifetime back into space. This material will eventually form into future stars and planetary systems.
IC443 is thought to have been formed between 30,000 and 35,000 years ago and is located about 5,000 light years away,

Avevo già fotografato questa bellissima nebulosa diffusa "nel 2015": altri tempi, altro setup , altri software. Finalmente ci ho riprovato, curioso di vedere dove potevo spingermi con i nuovi strumenti a disposizione.
Questo mosaico di 2 pannelli è l'immagine della Nebulosa Anima, nella costellazione di Cassiopea, conosciuta come Nebulosa Embrione ed anche con le sigle Sh2-199 , "W5" e "IC 1848", che è l’ammasso aperto associato alla nebulosa. Al suo interno vi sono anche altri ammassi stellari giovani come Collinder 33 e 34. Fa parte della vasta regione di formazione stellare delle nebulose Cuore e Anima ( "complesso W3/W4/W5") distante dalla Terra 7000-7500 a.l.
Rispetto alle ultime nebulose fotografate (come la "Sh2-132" , "DWB111" e la "Sh2-157" ), l'elaborazione di questa nebulosa è stata più semplice perchè già con le prime sessioni di acquisizione c'era un buon segnale quindi con 13h di integrazione per pannello ho potuto evidenziare dettagli e colori senza alterare l'immagine con strani artefatti o eccessivo rumore.
Devo ammettere che il risultato è alquanto appagante, ammirando le tante formazioni nebulari, come la "IC 1871" e LBN673, i cui contorni sono illuminati da stelle massicce, o gli intrecci filamentosi delle nebulose oscure e le sfumature cromatiche tra nubi HII e OIII che si fondono insieme creando questa forma unica. Veramente spettacolare!
______________
I had already photographed this beautiful diffuse nebula "in 2015": different times, different setups, different software. I finally tried again, curious to see how far I could go with the new tools available.
This two-panel mosaic is an image of the Soul Nebula, in the constellation Cassiopeia, known as the Embryo Nebula and also referred to as Sh2-199, "W5" and "IC 1848", which is the open cluster associated with the nebula. It also contains other young star clusters such as Collinder 33 and 34. It is part of the vast star-forming region of the Heart and Soul Nebulae ( " W3/W4/W5 complex") 7000-7500 light years away from Earth.
Compared to the latest nebulae photographed (such as "Sh2-132" , "DWB111" and "Sh2-157" ), processing this nebula was easier because there was already a good signal with the first acquisition sessions, so with 13 hours of integration per panel I was able to highlight details and colors without altering the image with strange artifacts or excessive noise.
I must admit that the result is quite satisfying, admiring the many nebular formations, such as "IC 1871"and LBN673, whose edges are illuminated by massive stars, or the filamentary interweavings of dark nebulae and the chromatic nuances between HII and OIII clouds that blend together creating this unique shape. Truly spectacular!

Second completed image of 2021 and the first complete one from my local astronomy club's dark site, an hour and a half outside of Houston. We finally had the first clear new moon weekend of the year, and myself and many others in the club decided we had to take advantage of it. It was a beautiful night with no clouds and the dew kept at bay. Had to image something unique for galaxy season and I settled on Markarian's Chain in Virgo. I framed to to get as many individual galaxies as I could in one shot.

Explanation: What caused the Crescent Nebula? Looking like an emerging space cocoon, the Crescent Nebula, visible in the center of the above image, was created by the brightest star in its center. A leading progenitor hypothesis has the Crescent Nebula beginning to form about 250,000 years ago. At that time, the massive central star had evolved to become a Wolf-Rayet star (WR 136), shedding its outer envelope in a strong stellar wind, ejecting the equivalent of our Sun's mass every 10,000 years. This wind impacted surrounding gas left over from a previous phase, compacting it into a series of complex shells, and lighting it up. The Crescent Nebula, also known as NGC 6888, lies about 4,700 light-years away in the constellation of Cygnus. Star WR 136 will probably undergo a supernova explosion sometime in the next million years. (text: apod.nasa.gov/apod/ap071111.html)

NGC 7822 è una nebulosa a emissione visibile nella costellazione di Cefeo.
La nebulosa presenta al suo interno alcune nebulose oscure e dista dal sole 2740 anni luce.
Si individua nella parte orientale della costellazione di Cefeo, circa 9° a nord della brillante stella Caph, in un tratto della Via Lattea fortemente oscurato da polveri interstellari e nebulose non illuminate; il periodo più indicato per la sua osservazione nel cielo serale ricade fra i mesi di luglio e dicembre ed è notevolmente facilitata per osservatori posti nelle regioni dell'emisfero boreale terrestre, dove si presenta circumpolare fino alle regioni temperate calde.

Entering the Perseus Arm of the Milky Way galaxy, the Hullbull Remote Space Telescope catches an infrared image of three runaway stars creating bow shock waves as they crash through dusty interstellar material.
Not a real space photo. Light art.
Composite of two exposures: first exposure using Waterworld technique (handheld) to create the nebula patterns. Second exposure on tripod using LEDs to create dense small starfield using method involving water droplets and white, yellow, red, green, and blue LEDs. Waterworld nebula pattern and dense starfield patterns completed using 100mm macro lens.
Inspired by WISE image of Zeta Ophiuchi
The Veil Nebula in Cygnus, with its intricate structures, is one of my preferred nebulas in the night sky and is the result of a supernova which happened some 10,000 or 20,000 years ago.
This image is the re-processing of data taken in 2021, whose first version was published here astrob.in/93bsj3/C/ and I may say that this time I was able to achieve what I envisioned to this photo.
I hope you enjoy.
