Explanation: A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright cluster stars are seen just below the prominent dark dust cloud near picture center. Notable near the 7 o'clock position in this wide, detailed view are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation, these cosmic tadpole shapes are about 10 light-years long. (Text from apod.nasa.gov/apod/ap060815.html)

Ieri sera, sfidando come sempre l’inquinamento luminoso cittadino, ho catturato le splendide galassie M65 e M66 nella costellazione del Leone. Con il mio SkyWatcher 200/1000 e due ore di posa, emergono i dettagli affascinanti di queste due isole di stelle a circa 35 milioni di anni luce da noi.
M65, in basso, appare elegante e poco disturbata, mentre M66, in alto, mostra le sue strutture deformate, segno di interazioni cosmiche passate.
Un viaggio nello spazio profondo, direttamente dal cuore della città! 🚀✨

For thousands of years, comets were omens for diasters. To ancient Hindi, it signified disruption in the order of the world; to ancient Chinese, it meant famine and war; to medieval Europeans, it foretold upcoming diseases...
Our ancestors lived in a time before Internet, before television, before radio, before books. Back then the nighttime was simple. It was just them and the unchanging starry sky, signifying the divine creators' perfection. This is why the sudden appearance of comets disrupted the heavenly orders, and it brought them fear and guilt.
Today, we celebrate their arrival with overwhelming joy and curiosity. We look at them through telescopes with a sense of wonder and none of the fears. To me, it marked the happy ending of our millennia-long story with comets, a story of how we learned to use knowledge to conquer fear.

Also know as The Seven Sisters, Pleiades is an an asterism and an open star cluster approximately 444 light years from Earth. The cluster, located the constellation Taurus, is dominated by hot blue and luminous stars that formed within the last 100 million years.
An asterism is a pattern or group of stars that can be seen in the night sky. Asterisms range from simple shapes of just a few stars to more complex collections of many stars. The larger brighter asterisms are useful for people who are familiarizing themselves with the night sky. For example, the asterism known as the Big Dipper comprises the seven brightest stars in the constellation Ursa Major.

In the fascinating southern night sky, there's a constellation that has captivated the curiosity of humans for thousands of years, known as Corona Australis, or the Southern Crown. Nestled within the arms of this celestial crown is the Corona Australis Molecular Cloud, an interstellar dust cloud full of secrets that we're only just beginning to understand. This is not your everyday dust, the kind you find under your bed or on your bookshelf. No, this is cosmic dust, complex molecules and tiny grains born from the ashes of stars. It's the stuff of life - organic molecules - scattered across the cosmos, whispering the tale of stars long gone.
Interstellar dust clouds like the one in Corona Australis, suspended in the cold and dark space, might seem desolate and barren. Yet they are cosmic cradles, nurturing new stars and possible worlds. As we gaze upon such distant wonders and strive to comprehend their mysteries, we come one step closer to reading the cosmic origin of our own story written among the stars. As we explore, we discover that the universe is not merely above us but also within us; for we are all made of star stuff.
Also known as Cadwell 4, it is a bright reflection nebula of magnitude 6.8 located in the constellation of Cepheus (the King), the dust in this region that creates the nebula is illuminated by a magnitude 7 star. It is 1,300 light years distance from Earth.

Centaurus A (also known as NGC 5128 or Caldwell 77) is a galaxy in the constellation of Centaurus.
In visible light, the galaxy seems elegant and beautiful - an elliptical central bulge surrounded by a gracefully warped swath. But in radio waves and X-rays, its true nature of violence and chaos is revealed - a monstrous, actively feeding black hole gobbling up everything nearby, shooting its victim’s corpses into space, and twisting the whole galaxy in the process.
The black hole and its feeding events are not visible in this image, but studies in radio and x-ray reveal a truly spectacular scene: youtu.be/bOjCrVQusYI
The jets are so powerful that their trails extend far beyond the galaxy itself, stretching millions of lightyears into space. Interestingly, some models suggest that the jet materials can eventually cool down and fall back to the black hole, creating a feeding cycle.

The image shows the core of the Heart Nebula (Melotte 15), a breathtakingly beautiful cluster of young, hot stars and dark dust clouds. The stars within this cluster are incredibly young, with some estimated to be only a few hundred thousand years old. Yet already they shine with a brilliance that puts our own sun to shame.

This is a single 300 second image in colour of Messier 31, The Andromeda galaxy.
considering this is a single 5 minute frame there is a good amount of data to be able to resolve some detail in the dust lanes.
10 million light years away and one of the brightest spiral galaxies in the night sky, NGC 253 (The Sculptor Galaxy) is going through an extremely active period of star formation and is likely home to one or more massive black holes at its center.

Lying at a distance of 1530 light-years away, NGC 1528 is estimated to be between 270 and 370 million years old (depending on the source). Comprised of approximately 100 member stars spanning approximately 16 arc-minutes in diameter and measuring at least 8.78 magnitude, this cluster is well detached from the background sky owing to the fair number of bright member stars in the central core. NGC 1528 is best observed during fall and winter when it is furthest north of the celestial pole after the end of astronomical twilight. (text from cs.astronomy.com/asy/m/starclusters/463289.aspx)

Explanation: Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only glimpsed through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy. Even though IC 342's light is dimmed by intervening cosmic clouds, this deep telescopic image traces the galaxy's obscuring dust, blue star clusters, and glowing pink star forming regions along spiral arms that wind far from the galaxy's core. IC 342 may have undergone a recent burst of star formation activity and is close enough to have gravitationally influenced the evolution of the local group of galaxies and the Milky Way.

The Spaghetti Nebula is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. The nebulous area has an almost spherical shell and a filamentary structure. It is believed that the stellar explosion left behind a rapidly spinning neutron star known as a pulsar in the nebula core, emitting a strong radio signal. Sh2-240 is approximately 3,000 light-years from earth.

Amidst the vast expanse of the Milky Way, in the constellation of Sagittarius, lies a cosmic nursery - The Trifid Nebula (also known as M20 or NGC 6514). It is a place where new stars are born and where the very building blocks of life may be taking shape. In its vicinity, hydrogen, the most abundant element in the universe, is compressed and heated to such extremes that it begins to glow, illuminating the surrounding environment in a dazzling display of red, blue, and pink hues.
The Trifid Nebula is also a unique blend of three distinct astronomical phenomena. The emission nebula, characterized by the radiant glow of ionized gas, is responsible for the vibrant red hues. Meanwhile, the blue reflection nebula, comprised of scattered light from nearby stars, adds an ethereal shade of cerulean to this celestial tapestry. Finally, the dark nebula, with its obscuring clouds of dust and gas, creates the striking dark lanes that give the Trifid Nebula its name and signature appearance.
At the heart of the Trifid Nebula lies a brilliant, massive star - a beacon of light and energy, whose powerful winds and radiation sculpt the surrounding gases, carving intricate patterns into the surrounding material. This star, only about 300,000 years old, is a veritable infant by cosmic standards. Yet, its immense power and influence help to shape the very environment in which it was born.

Hubble originally observed M16 in 1995, and the image became an overnight sensation. It was the first highly detailed look astronomers ever got into a star-forming region. In the centre of the image is the famous Pillars of Creation, where new stars are being born inside the dark clouds. It is formed by nearby stars radiating a stupendous amount of UV light upon the interstellar medium. The radiation washes over the dust clouds, eroding away the lower-density materials and carving the three distinct towers.
The nebula is going through constant changes on a massive scale. The interstellar gases move at a speed of over 700,000,000 metres per hour. That's enough to get you to the moon in 30min. Since the first image of the nebula, some of the dust streams have travelled trillions of kilometres. In fact, there's an image on NASA's website showing exactly how far the dust has travelled over the past 26 years, but in this image, the change is less than half a pixel. How immense the universe and how short-lived our species!

Astronomers using NASA's Hubble Space Telescope have assembled a comprehensive picture of the evolving universe – among the most colorful deep space images ever captured by the 24-year-old telescope.
Researchers say the image, in new study called the Ultraviolet Coverage of the Hubble Ultra Deep Field, provides the missing link in star formation. The Hubble Ultra Deep Field 2014 image is a composite of separate exposures taken in 2003 to 2012 with Hubble's Advanced Camera for Surveys and Wide Field Camera 3.

Between Cepheus and Cassiopeia constellation, a unique object exists. Commonly named as the Bubble nebula, NGC 7653 is the result of a violent process where the massive star BD+602522, 45 times larger than our Sun, is burning at an incredible rate and the outflow of radiation and stellar wind blasts and compresses the nearby gas and dust, creating a layer around the star. This bubble has about 7 light-years - if Earth would have 1 mm diameter, 7 light-years would be around 5,000 km, about the same distance from Lisbon to Moscow. Pretty amazing…
In the same field of view, the open cluster Messier 52 and the nebula NGC 7538, a very active stellar nursery and “home” of the largest protostar known with the size of 300 times the Solar System.

Got back out to the local club dark site this weekend for a (mostly) clear new moon night (clouds rolled in around 3AM). Been meaning to hit this target for some months now but never had the weather to do so. Glad I can mark it off the list now.
LDN673 is a dense region of dust located in Aquila. The high cloud density prevents starlight from behind the clouds from passing through. The shape sort of reminds me of a virus of some sort.
Some comments: I really need to fix the spacing on my scope. With LRGB images, it is especially apparent that the channels don't line up well at the corners - and the green channel really didn't want to play well with this image. I miss having a flatfield astrograph and the FSQ106 cannot come soon enough. This was also my first time using MureDenoise instead of the usual TGVDenoise/MultiscaleMedianTransform linear noise reduction technique. I am very impressed with Mure's capabilities and will add it to my toolset.

The image depicts the famous "Bubble Nebula", indicated with the acronyms "NGC7635", C11, LBN548, Sh2-162. In its surroundings together with the well-known open cluster "M52 (NGC7654)", with its prospective neighbor MWSC 3726 (from the Milky Way Star Cluster catalog), other Ha emission nebulae stand out, such as "NGC7538", Sh2-159, Sh2-161, and dark nebulae such as LDN1231, LDN1232, LDN1225. (see notes on the image)
Probably the 5h and 45 min of narrow band integration is not much (it would have been better to integrate 12-15h), but in this period of the year (winter) it would take even months.
Nevertheless, the f/4 focal ratio gave me the ability to extract a decent amount of weak signal without carrying too much noise.

This galaxy marked the beginning of our understanding of the universe's immensity.
Merely 100 years ago, Andromeda was thought to be a nebula, and many astronomers at the time believed that our Milky Way was the only galaxy in the universe. Not long after, Edwin Hubble made his famous observation, confirming Andromeda as a galaxy, and our galaxy was just one of many. From that moment, our universe expanded, and we never looked back.
The background may look a bit messy, but it was intentionally so. Every dot in the image is a star, and there are well over 10,000 stars in the background. The galaxy itself contains about a trillion stars, many of which have their own planets. Maybe, just maybe, some of them could even harbour life.
Another fun fact about Andromeda is that it's on a head-on collision course with our Milky Way. They will collide about 4.5 billion years from now, performing a spectacular cosmic dance and merging into a new elliptical galaxy. Would humans still be around to witness the show?

Explanation: Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. This sharp, colorful image reveals the galaxy's bulging central core cut by obscuring dust lanes that lace NGC 4565's thin galactic plane. An assortment of other galaxies is included in the pretty field of view. Neighboring galaxy NGC 4562 is at the upper right. NGC 4565 itself lies about 40 million light-years distant, spanning some 100,000 light-years. Easily spotted with small telescopes, sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed. (Text: apod.nasa.gov/apod/ap100304.html)
