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".

Questo inizio anno 2026 continua ad essere molto singolare: si susseguono settimane di meteo sfavorevole e instabile. Le sere/notti serene sono state rarissime; infatti ho dedicato alla famosa Nebulosa Medusa, catalogata con la sigla IC 443 nella costellazione dei Gemelli, tutto il mese di febbraio. E non immaginavo fosse una nebulosa così evanescente ed ostica dal punto di vista elaborativo, tanto che ho dovuto utilzzare oltre 25h di integrazione per riuscire a gestire un disceto segnale. Devo ammettere che durante l'acquisizione delle immagini il cielo non è mai stato molto trasparente e la luna in un paio di sessioni ha peggiorarto le cose, con la conseguente presenza di discreto rumore e gradiente.

Ho fatto molti tentativi per cercare di evidenziare il segnale soffocando il rumore con i tool a mia disposizione. Fortunatamente l'applicazione Siril continua a grandi passi ad arricchirsi di nuovi scripts di terze-parti sempre più performanti, interessanti e miglliorati. Uno fra tutti il nuovo antirumore SyQon-Prism che in questa occasione si è dimostrato leggermente migliore rispetto all'ottimo GraXpert. E così sono riuscito a domare il rumore di fondo a favore del segnale e grazie al rapporto focale f/4 si riesce a scorgere la debolissima presenza di Ha e OIII attorno a questa bellissima nebulosa.

Altra faticaccia è stato il riverbero della stella multipla, composta da 3 componenti, Eta Geminorum, nota come Propus o Tejat Prior, che presentava un alone antiestetico credo di natura ottica. Solo con PS ho cercato di gestirlo nel miglior modo possibile.

_________________

This start to 2026 continues to be very peculiar: weeks of unfavorable and unstable weather follow one another. Clear evenings/nights have been extremely rare; in fact, I dedicated the entire month of February to the famous Jellyfish Nebula , catalogued with the acronym IC 443 in the constellation Gemini. And I didn't imagine it was such an evanescent and processing-challenging nebula, so much so that I had to use over 25 hours of integration to manage a decent signal. I must admit that during image acquisition, the sky was never very transparent, and the moon made things worse in a couple of sessions, resulting in a fair amount of noise and gradient.

I've made numerous attempts to highlight the signal while suppressing the noise with the tools at my disposal. Fortunately, the Siril application continues to grow rapidly with new, increasingly efficient, interesting, and improved third-party scripts. One of these is the new SyQon-Prism noise suppressor, which on this occasion proved slightly better than the excellent GraXpert. Thus, I was able to tame the background noise in favor of the signal, and thanks to the f/4 focal ratio, I was able to discern the very faint presence of Ha and OIII around this beautiful nebula.

Another hardship was the reverberation of the multiple star, composed of three components, Eta Geminorum, known as Propus or Tejat Prior, which presented an unsightly halo, I believe of optical origin. Only with PS did I try to manage it as best as possible.

M1 - An Explosion in Space

Sky-watchers on Earth witnessed and wrote about a bright “supernova” (literally meaning “new star”) in the year 1054. What they were really viewing was the birth of rapidly expanding clouds from an exploding star. By the year 2021, roughly one thousand years later, these clouds have covered a distance of nearly 10 light years, and they continue to expand at a rate of about 1000 kilometers per second.

In 1840, after viewing this supernova remnant through a telescope and sketching it, astronomer William Parsons thought that it looked like a crab, and the name “Crab Nebula” caught on. If you can't see such a crab, you're not alone! With modern cameras we can collect so much more light and detail than that which could be previously captured with the eye and eyepiece combo, so to me (and probably to you) it looks more like, well, an explosion in space.

IC5070 (the Pelican nebula) is located in the constellation of Cygnus at approximately 1800 light years from Earth. You can see on the right of the image a large pillar of gas and at the tip of this is a Herbig-Haro object.

Herbig-Haro 555 is a narrow jet of gas and matter, ejected by newly born stars at speeds of several hundred kilometres per second. It collides with nearby gas and dust in the interstellar medium, producing bright shock fronts that glow as the gas is heated by friction while the surrounding gas is excited by the high-energy radiation of nearby hot stars.

LDN 1622 is located near the galaxy plane in the constellation of Orion. It is close to Barnards loop, a huge cloud that surrounds the emission nebulas found in the Belt and Sword of Orion.

LDN 1622 is thought to be much closer to the more famous Orion Nebula, perhaps only 500 light years away.

The REALLY interesting thing about this image is that I have got a pre-main-sequence (PMS) star .... Please take a look at my website to find out more www.swagastro.com/ldn1622.html

Before you draw your conclusions about this image, please read the description.

The sky and foreground were captured back to back at the same focal length and with the same equipment from a single tripod position.

The camera position was roughly 2 miles away from the mountain station, and the telescope/camera combination has an extremely narrow field of view of only 1.5° x 2°. The resulting telephoto compression makes the otherwise tiny Orion Nebula appear huge.

Two years ago, I had already captured a similar deepscape, but I was never really satisfied with it. The problem was lacking data for my sky, especially in the green channel, as clouds moved in towards the end of the imaging session.

Of course, I could have recaptured the missing data or the entire Orion Nebula from a different place, but that's not my style. After waiting two years for an opportunity to reshoot the image, I finally got my chance this February.

The weather this time was perfect, which made capturing the sky pretty straightforward, but otherwise, the conditions were still as demanding as 2 years ago.

Getting the foreground in focus with a monochrome micro 4/3rd astro-cam and RGB filters through a 500mm f/5.6 telescope is a real pain. Furthermore, snowcats grooming the slopes caused constantly changing, extremely bright illumination. Considering this, I am quite happy that I was able to capture a usable foreground.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Nikkor 500mm f/4 P Ai-s on a ADM dovetail rail on the top of my optical tube. I used DeepSkyStacker to combine all frames and then 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 in level, then curves. I used the color sampler tool and levels to do my best to keep the background space black. I then using my skillset and relyed on Astronomy Tools Action Set, and dodging and burning a bit to give the image the finishing touches.

Messier 56 is a globular cluster of stars in the constellation of Lyra. It was discovered in 1779 by Charles Messier.

Spanning 84 light-years in diameter and approx 32,900 light years away it is believed to be about 13.7 billion years old, It is believed to contain around 80,000 stars.

​

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.

NGC 4038 and NGC 4039 are known as the Antennae, or sometimes called the "rat-tail" galaxies. They are located near the western edge of Corvus.

This pair of interacting galaxies was discovered by William Herschel in 1785. The Antennae Galaxies are the nearest and youngest example of a pair of colliding galaxies. About 1.2 billion years ago, the Antennae were two separate galaxies. Simulations of colliding galaxies suggest that the two will eventually form a single elliptical galaxy.

Located about 5000 light years from Earth, the center image shows the Rosette star formation region. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. A survey of the nebula with the Chandra X-ray Observatory has revealed the presence of numerous new-born stars inside optical Rosette Nebula and studded within a dense molecular cloud. Altogether, approximately 2500 young stars lie in this star-forming complex, including the massive O-type stars HD 46223 and HD 46150, which are primarily responsible for blowing the ionized bubble. Most of the ongoing star-formation activity is occurring in the dense molecular cloud to the south east of the bubble.

This is a part of my new project currently under construction: Part One and two of ten panels. (this image is made up of two panels) This will eventual form a skyscape including Caldwell 49 up to and including the Cone Nebula and Christmas Tree Cluster.

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus. The remarkable shape of the emission nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen. The distance of the nebula complex is though to be approx 1800 light years away.

Avevo iniziato nel 2015 ad acquisire queste immagini flic.kr/p/CCbNR7 , flic.kr/p/CCejHs , flic.kr/p/CCi68y per realizzare un mosaico con 5 pannelli. Purtroppo solo la 1° acquisizione è stata buona, mentre le altre hanno avuto vari problemi e il 4° pannello aveva poca integrazione quindi speravo di rifarmi quest'anno, ma non è stato possibile.

Malgrado ciò, ho unito i 4 pannelli ed ho tentato di elaborare il mosaico nel modo migliore possibile.

Il risultato (work in progress) mi è sembrato molto gradevole quindi lo condivido con piacere con voi.

I dati EXIF sono riferiti all'acquisizione del 4° pannello in data 20/08/2016

_______________

I started in 2015 to acquire these images flic.kr/p/CCbNR7, flic.kr/p/CCejHs, flic.kr/p/CCi68y making a mosaic with 5 panels . Unfortunately only the 1st acquisition was good, while the others have had various problems and the 4th panel had lower integration so I was hoping to solve this year, but it was not possible.

Despite that, I joined the 4 panels and attempted to process the mosaic in the best possible way.

The result (work in progress) seemed very nice so I share it with pleasure with you.

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. 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 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.

This is a montage of the best bits of 2016 ..... It's been an interesting year for sure and I've had some imaging fun!

2017 is already turning into an interesting year, with things in the pipeline that I am looking forward to.

There are many hundreds of hours of total exposure time in this complete montage. Some of the images have been published in magazine and one of them got a NASA APOD as well.

I hope you enjoy looking over it as much as I've enjoyed the imaging and processing time spent doing each and every image on here.

I had imaged M78 on three different nights, but every night there was something that went wrong.

For those who don't know their way around the night sky, this object is in the constellation of Orion. In the picture it's center right, at the bottom is the Flame Nebula and at the top is a portion of Barnard's Loop

On the first night I had set my lens to f5.6 and ended up with ugly star diffraction spikes, the second night I was ever so slightly out of focus and the third night I didn't get enough good shots because some haze moved in and the stars started to bloom. When that happens it can ruin the final result.

This image is from the 2nd night and I was able to do some star surgery to get them to look round and within color range.

Apologies to my Flickr friends, but right now I am uninspired by the drab look of the New Mexico landscape so I've turned my gaze to the heavens. We have a lot of clear skies right now, so why not?

This one turned out way better than I anticipated!

The Eastern Veil nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus, located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a 7000 years old, faint supernova remnant, covering roughly 3° on the sky (almost 6 full moons). The red hues in this image are from ionized hydrogen gas clouds, emitting light in the H-alpha wavelength, while the cyan hues are from oxygen ions.

Planetary Nebula in Orion

A dying star.

==================================

Image exposure: 60 minutes

Image field of view: 9.86 x 9.86 arcmin

Image date: 2021-12-31

==================================

This object bears a striking resemblance to the much closer NGC 1535 which I posted a few weeks ago.

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.

(wikipedia)

The Rosette Nebula is relatively easy to find, it is located about a third of the way between the star Betelgeuse in Orion and the star Procyon in Canis Minor.

In honor of tonight's full moon, here's an image from last month's full moon which I photographed about an hour after it rose.

The moon itself here is my capture, and I have used a deep space filter layered behind it, giving a three dimensional element and experience.

The Dumbbell Nebula (also known as the Apple Core Nebula, M 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. [wikipedia]

Red hydrogen emission and blue reflection nebulae, dark molecular clouds and a bright star sitting in the middle, flooding the scene its yellow light... Sounds like the Rho Ophichui region?

Sure. There is, however, another smaller, but similarly colorful area in the sky:

Meet the Cave Nebula!

Officially designated Sh2-155, the Cave Nebula in the constellation Cepheus, is a diffuse nebula of ionized hydrogen with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth. It lies within a larger complex containing emission, reflection, and dark nebulosity.

The name "Cave Nebula" for Sh2-155 was coined by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth. Earlier, the name was already used to refer to another brighter but unrelated reflection nebula in Cepheus, known as Ced 201. The name's application to Sh2-155 has come into vogue through the nebula's inclusion in Moore's Caldwell catalogue as object Caldwell 9.

NGC 7635 a.k.a. Bubble Nebula

……………………………................

Space is full of things / situations / events that intrigue us, NGC7635 being one of those. In short and for everyone to understand, a massive star is caught in a "bubble". This star is almost 50 times larger than the Sun and the emitted radiation is about 1 million times stronger than it, producing a stellar wind that exceeds 5 million km per hour, wind that pushes dust and gas outward creating thus a shell or a bubble, a situation that obviously led to the popular name of this nebula.

As general information, the Bubble Nebula is an emission nebula with a diameter of about 7 light-years, located in the constellation Cassiopeia, at a distance of over 7000 light-years from Earth and it was discovered in 1787 by the British astronomer, William Herschel.

Specialists believe that in a short time ( meaning in the next 10-20 million years), the "guilty" star will consume its energy resources, and will explode, forming a supernova.
