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.

NGC 2403 (nota anche come C 7) è una grande galassia spirale visibile nella costellazione della Giraffa. Creduta all'inizio una delle galassie a noi più vicine (appena 8000 anni luce) , si scoprì in seguito la sua distanza reale, di 8 milioni di anni luce.
La galassia appartiene al Gruppo di galassie di M81, uno dei più vicini al nostro Gruppo Locale, i cui membri principali si trovano nell'Orsa Maggiore. Fu la prima galassia all'esterno del Gruppo Locale in cui furono identificate delle variabili Cefeidi,la galassia è anche conosciuta per le supernovae apparse in essa: SN 1954J, 2002kg e SN 2004dj. Il suo nucleo è ricco di regioni HII, ossia aree di idrogeno ionizzato in cui avvengono fenomeni di formazione stellare, fenomeno abbastanza raro di norma nelle regioni centrali delle galassie.

LBN 534 is a molecular cloud stretching across more than 1.5 degrees of sky in the constellation Andromeda. It is about 1400 light years away and about 36 light years ( 211600000000000 miles ) long. The blue reflection nebula within LBN 534 is designated as vdB 158 and is lit by the bright star HD 222142.
There is also a planetary nebula PK110-12.1 located near the bottom center of the image. It was discovered by Luboš Kohoutek in 1963, the same astronomer that discovered Comet Kohoutek, which was visible to the naked eye in 1973. Planetary nebulae only last a few tens of thousands of years -- a mere blink in cosmic time -- before their material scatters into space. A "planetary" nebula is actually a shell of gas and dust that's ejected from a dying star. The name "planetary nebula" is a historical misclassification that comes from when astronomers first observed these objects. They thought they were looking at gas planets, and William Herschel named them after planets because they appeared round. PK110-12.1 appears dark green in this image. There are no green stars (another interesting topic), so see if you can locate it in the sea of dots.
Generally speaking, green colors in a nebula are due to forbidden transitions in ionized Oxygen. Forbidden transitions refer to transitions between energy levels that are not allowed by the selection rules of quantum mechanics under normal circumstances. However, they can still occur under certain conditions, such as in the presence of external fields or through higher-order processes.

The Pacman Nebula is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm.
It includes a small, yet noticeable open star cluster (IC 1590) and dynamic dust lanes. This nebula gets its name from the classic video game character it resembles.
The prominent lane of dark dust cutting into this glowing nebula creates the “mouth” of this nebulas shape.
First picture with the new Scope ! I was really impressed by the quality of my subs.
It could have been better without the 80% Moon and the clouds (~10 subs wasted), but at the end, almost 40 subs of 10 min was enough to get some nice details.
So as I'm tired of clouds, this time I'll not complain about it and just wish you clear skies!! :p

My Focuser on the main telescope would not calibrate so I had to send it away to get looked at. So I have turned the Clock back to my old school days when I first started out in Astro.
Nikon 300mm D F4 AF-S come from the 2000s days . There is no auto focus on this rig its all manual focus at the start of the Night and tape lens. In the lens defence for its age even though I checked focus each night it never moved. So this setup is just nikon lens, Filter draw With Optolong LeNhance filter inside( for light pollution) and the QHY183C colour camera.
This is 29 hour's worth of data in the hope the lens worked out well. To say that I am over the moon with the end result is an understatement who said its complicated. I had thought of more shots but 29 hours is plenty as I have not heard back I will find another target to try.

El resto de supernova de Vela, también llamado Vela XYZ, SNR G263.9-03.3 y AJG 8,1 es un resto de supernova situado en la constelación de Vela. Es uno de los restos de supernovas más estudiados y más cercanos a la Tierra. Aunque se superpone al resto de supernova Puppis A, este último está unas cuatro veces más lejos.
El resto de supernova de Vela está asociado al púlsar de Vela (PSR J0835-4510): la relación entre ambos objetos astronómicos, realizada por astrónomos de la Universidad de Sídney en 1968, fue la prueba directa de que las supernovas dan lugar a estrellas de neutrones. La rotación de este púlsar, cuya frecuencia es de aproximadamente 11,2 Hz, ha sido estudiada exhaustivamente desde su descubrimiento. Fue el primer púlsar en donde se detectó una «falla» o «defecto» en su rotación; cuando se detectó de nuevo, dos años y medio más tarde, quedó claro que dichas «fallas» eran grandes y frecuentes. En estos episodios, la frecuencia de rotación se incrementa en unos 20 μHz. (Wikipedia)

Another night in Valle Stura, but this time at Sant'Anna di Vinadio's lake.
The place is relly nice for night photography, even if mountains cover a bit Milky Way core.
This is a revisit of the CED 122 region near the Coal Sack dark nebula.

this photo unfortunately reveals some issues with this lens wide open- namely halos around bright stars and lens flare around the brightest star (Mimosa Beta Crux)
Removed as much of the halos as I could in processing but Mimosa is still very apparent, Could have cropped it out I suppose.
Will need to try it closed a couple of stops next time
My latest image from the backyard is the dynamic-looking 'Lion Nebula' in the constellation Cepheus. (I love the colors in this one)
This image includes exactly 7 hours of total exposure time (84 x 300s) using the little RedCat 51 telescope with a color camera and light pollution filter attached.
The Optolong L-eXtreme filter has officially become my most used filter of all time - and it consistently provides me with useful data from my Bortle 6 backyard.
Dual-narrowband filters have really made astrophotography from the city a lot more obtainable.

Clear skies!
This image, shot during May to July 2024, shows a heavily crowded are in constellation Cepheus, with a blend of several nebula types. In the center, pillars of dust create a wormlike structure called LDN 1217, which ends in a bluish reflexion nebula (VdB 152). In the background, more dark nebulas can be seen, in some parts being lit by hot blue giants stars. In this area, it partially blocks the red light coming from the Ha strands farther away, which impairs the sense of perspective.
This is my longest project so far (61h29) and one of the hardest. Why? Not because of technical issues but in striking a balance between all these nebulas in a way that any of them overwhelms the others and thus show the richness of this area.
Have I achieved it? Perhaps yes, to my eye. Or maybe not… But the important is that I am quite happy with it.

This open star cluster is called Seven sisters or Al-Thuraya in Arab culture. It composed of hot blue young stars that surrounded by a reflection nebula that appears as a luminous gas nebula due to reflection of those star’s light. It is the nearest object to Earth among Messier objects. Its distance is 444 ly from Earth.

IC 434 is an emission nebula visible in the constellation of Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.
This is an H II region that extends south of Alnitak, on the southwestern edge of the large Orion B cloud; it has a very elongated shape in a north-south direction and receives the ionizing wind directly from the star σ Orionis, a bright member of the large Orion OB1 association.
The nebula reaches 70' in length and is easily shown in long exposure photos or CCD images, although its thickness is only a few arc minutes.
The temperature of the region was measured using various methodologies and exploiting various radiation ratios, initially obtaining values between 8000 K and 7600 K;
subsequently this value was reduced to 3360 K and even less depending on the map taken as reference.[3] A study on electronic temperature conducted in 1992 instead provided a value more similar to the previous ones, which is around 6000 K.

Located near the well known Messier 8, NGC 6559 is located slightly above the center of this image. It is a reflection(blue) and emission nebula(red), located 5000 light years away in the constellation of Sagittarius. Towards the left of center is the emission nebula IC 4685. A dark nebula, resembling a river, runs through IC 4685. Directly below these nebula is the emission and reflection nebula IC1274. Many other dark nebula, emission nebula and reflection nebulas are also seen in the image.
