The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature.

This is my latest deep-space photography shot. This was from October 26th at Lake Hudson Recreational Area in Michigan. This image is from 68 minutes of data exposure (34 photographs each at 2-minute exposures).
Durante lo Star Party del Gruppo Astrofili Catanesi astrofilicatanesi.net/ (02-04/08/2024), il cielo pur essendo discreto a causa dell'Inquinamento luminoso non mostrava bene la Via Lattea a declinazione negativa. Ho dovuto scegliere un target vicino allo zenit: il Muro del Cigno. Una vasta e ricca nebulosità che fa parte della grande nebulosa Nord America (NGC7000) it.wikipedia.org/wiki/Nebulosa_Nord_America.
La prima notte purtroppo ho acquisito (non so cosa sia successo) senza raffreddare il sensore della ASI533MC-pro (circa 15°C). Speravo nella seconda notte ma a causa delle nuvole ho acquisito solo 5 frame.
Ciò malgrado l'immagine combinata era abbastanza buona. Ho deciso allora di riprendere da casa un pò di segnale in banda stretta per aggiungerlo all'immagine RGB ed enfatizzare il segnale H-alfa.
Sono rimasto piacevolmente sorpreso nel vedere durante l'elaborazione che la prima sessione di 43 frame a +15° aveva un segnale sufficente per regalarmi questo risultato.

During the Star Party of the Gruppo Astrofili Catanesi astrofilicatanesi.net/ (02-04/08/2024), the sky, although discrete due to light pollution, did not show the Milky Way well at negative declination. I had to choose a target close to the zenith: the Cygnus Wall. It is a large and bright nebulosity that is part of the great North American nebula (NGC7000) en.wikipedia.org/wiki/North_America_Nebula#:~:text=The%20...(NGC,its%20shape%20resembles%20North%20America.
Unfortunately the first night I acquired (I don't know what happened) without cooling the sensor of the ASI533MC-pro (about 15°C). I was hoping for the second night but due to the clouds I acquired only 5 frames.
Despite this the combined image was quite good. I then decided to take some narrowband signal from home to add it to the RGB image and emphasize the H-alpha signal.
I was pleasantly surprised to see during the processing that the first session of 43 frames at +15° had enough signal to give me this result.

The Pleiades also known as the Seven Sisters and Messier 45, is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus. The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years.
After lot's of clouds, rain and storms in Spain, I am really happy to be able to image this open cluster and reflection nebula in two short nights. A very simple capture and edit to kick off imaging during some moonless skies.

A complete mosaic of this region. Cygnus is very rich in nebulosity, in which North America nebula, Pelican nebula and Ha region around Sadr are the most recognizable even in nightscape photography due to its unique shape and stronger response. The remarkable shape located on a bottom right are supernova remnants, known as Cygnus Loop (or Veil Nebulae). Also the Crescent nebula put a little smile on my face when I saw it in my data as a little bonus :-)

NGC 2903
.................
Discovered over 200 years ago by astronomer William Herschel, this galaxy is just over 30 million light-years away and can be seen during the spring nights in the constellation Leo. NGC 2903 is very similar to our galaxy in both size ( abt 100.000 light years diameter) and structure, with both galaxies being classified as "barred galaxies”. What makes it stand out (or not, in terms of popularity) is its position in night sky, being a "field galaxy" or solitary galaxy, meaning it is not part of a larger group of galaxies and is not affected by any external gravitational force, thus being gravitationally alone.
I think that, despite its "shy" position in deep space, this galaxy deserves a popular name, especially since it is not an impossible target, a focal length of 5-600 mm being able to bring out some details.

Also known as Brocchi's Cluster or Al Sufi's Cluster, this open cluster (or asterism) is located in the constellation Vulpecula and forms the shape of a coat hanger. The background stars appear very orange from the significant amount of dust in the region. Although once thought to be a star cluster, more recent studies of the parallax of the stars indicate that the cluster is merely a chance alignment of stars thus more properly categorized as an asterism.

Nella mia vita di astrofilo non ero mai riuscito a dedicare il tempo necessario alla bellissima "Nebulosa Omega".
Questa nebulosa ad emissione, nel cui interno c'è attività di formazione stellare, è nota anche come nebulosa Cigno, nebulosa Ferro di Cavallo, nebulosa Aragosta o con le sigle "M 17" o NGC 6618, e si trova nella grande costellazione del Sagittario.
Grazie alla sua luminosità, al filtro a banda stretta, che ha tagliato buona parte dell'inquinamento luminoso, e all'integrazione generosa il risultato ottenuto è stato per me appagante. Se nell'immagine lineare era visibile soltanto il cuore della M17, lo strecth ha fatto risaltare anche le nebulose ad emissione più deboli che circondano M17. E questo ha evidenziato anche le nebulose oscure che con i loro intrecci tortuosi, insieme alle sfumature e bordi delle nubi Ha, eccitate dalle giovani e calde stelle al loro interno, danno un effetto di profondità a tutta la nebulosa.

In my life as an amateur astronomer I had never managed to dedicate the necessary time to the beautiful "Omega Nebula".
This emission nebula, in which there is star formation activity, is also known as the Swan Nebula, the Horseshoe Nebula, the Lobster Nebula or by the acronyms "M 17" or NGC 6618, and is located in the large constellation of Sagittarius.
Thanks to its brightness, the narrow band filter, which cut out a good part of the light pollution, and the generous integration, the result obtained was satisfying for me. If in the linear image only the heart of M17 was visible, the stretch also highlighted the fainter emission nebulae surrounding M17. And this also highlighted the dark nebulae that with their tortuous interweavings, together with the shades and edges of the Ha clouds, excited by the young and hot stars inside them, give an effect of depth to the entire nebula.

The Milky Way passes over the Owens Valley Radio Observatory near Big Pine, California. This 130ft dish is the largest of several radio telescopes onsite, and is presently used to listen for signs of extraterrestrial communications...I mean, study the sun's magnetic field.
Miguel and I embarked on a long weekend of astrophotography through the eastern Sierras and into the Owens Valley. This spot is near the White Mountains. If you are like me and have spent your entire life looking at muted night skies in light-polluted cities, please do yourself a favor and travel to a place in the middle of nowhere to experience the true beauty of a starry night. It is enchanting.
This was my very first time attempting astrophotography with my 645Z. I used the D FA 25mm f/5 at 25sec. I usually prefer my APS-C camera with built in GPS astrotracer for longer exposures and low ISO, but I wanted to try the Z...and it performed great. Actual EXIF is ISO 8,000 f/5, 25sec.
I did not count on the fact that the dish was moving the entire time, rendering long exposures blurry. Thankfully Miguel noted the motion blur and shouted out a heads up.
This was a long night, but very enjoyable cool summer-ish night.
Thanks for looking!

As I enter my 4th year of being an astrophotographer, I can finally tick this target off my list.
Barnard's Loop is a Hydrogen Alpha (the red stuff) rich emission nebula in the constellation of Orion. It's difficult to capture since it's a faint nebula. I've imaged it before but wasn't satisfied with the result.
And so, it became the 1st target of #EveryNewMoon, an imaging project Cory and I started for 2016.
I'll write more about the project in the next few weeks.

It was very difficult to work with such a rich star field. Shooting at 24mm meant millions of little pin-point stars. 2 Iterations of star reduction, and I'm scared that now the sky appears noisy. But in fact, it's just the ridiculous amount of stars in the image!

Discovered in 1784 by William Herschel, NGC 6979 is a supernova remnant in the constellation of Cygnus and is one part of the more well known Veil Nebula or Cygnus Loop. The source of the supernova was from a star 20 times the size of our sun exploding between 10 and 20 thousand years ago. The thin strands are made of heated and ionised gases. In this image the teal tones represent oxygen gas while the red tones represent sulphur and hydrogen gases. Recent measurements estimate the distance from Earth to be 2400 light-years.

Ho fotografato altre volte la bellissima "Nebulosa Aquila", ma non sono mai riuscito a raggiungere una buona integrazione che mi permettesse di elaborarla efficacemente. Questa volta, grazie al filtro multi banda stretta Optolong L-eNhance ho raggiunto un'integrazione di 13h senza essere assediato dall'Inquinamento luminoso. Il risultato personalmente mi soddisfa molto.
La Nebulosa Aquila, nota anche come "M16", "IC4703" o Regina delle Stelle, vasta e luminosa nebulosa ad emissione HII si trova in mezzo alla Via Lattea nella costellazione della Coda del Serpente e al suo interno ospita l'ammasso aperto di giovani stelle NGC 6611.
E' molto conosciuta per le formazioni singolari al suo interno, fra tutte i ""Pilastri della Creazione"".
Per le sue caratteristiche il FOV inquadrato presenta zone con intensità luminosa non omogenea con il cuore della nebulosa molto luminoso e le zone più esterne molto deboli; quindi ho dovuto trovare un buon compromesso per evidenziare le parti deboli e non bruciare quelle luminose.
Spero di esserci riuscito.
I have photographed the beautiful "Nebulosa Aquila" other times, but I have never managed to achieve a good integration that would allow me to process it effectively. This time, thanks to the Optolong L-eNhance narrow band multi-filter, I have achieved an integration of 13h without being besieged by light pollution. The result personally satisfies me a lot.
The Eagle Nebula, also known as "M16", "IC4703" or Queen of the Stars, a vast and bright HII emission nebula is located in the middle of the Milky Way in the constellation of the Serpent's Tail and within it hosts the open cluster of young stars NGC 6611.
It is well known for the singular formations within it, among all the ""Pillars of Creation"".
Due to its characteristics, the framed FOV presents areas with non-homogeneous light intensity with the heart of the nebula very bright and the outer areas very weak; therefore I had to find a good compromise to highlight the weak parts and not burn the bright ones.
I hope I succeeded.

The Heart Nebula (IC 1805) lies about 7,500 light years away from Earth in the Perseus Arm of the Galaxy in the constellation Cassiopeia. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. (ref: en.wikipedia.org/wiki/Heart_Nebula)
The Heart Nebula is located adjacent to the Soul Nebula forming a view referred to as the Heart and Soul Nebula. Now to splice the images together into a mosaic of the region.

Andromeda Galaxy a.k.a. Messier 31
……………..............................................
Andromeda, the largest galaxy in the so-called Local Group of Galaxies to which our galaxy also belongs, is 2.5 million light-years away and can be seen (even with the naked eye) in the constellation Andromeda. As general information, Andromeda is about 1.5 times larger than the Milky Way, with a diameter of 220,000 light-years (compared to the Milky Way which is 120-140,000 light-years in diameter) and contains more than 2 times as many stars. Although the first mention of this celestial object dates from 960, the first to give a more detailed description was the German astronomer Simon Marius, in the 1600s.
It should also be mentioned that Andromeda and the Milky Way are approaching with about 100 miles per second, experts estimate that in about 3-4 billion years the 2 galaxies will collide and thus form a new giant galaxy.
The attached image only shows part of Andromeda because the equipment I used was prepared for another target.

Praesepe (Latin for "Manger"), also known as the Beehive Cluster, is an open star cluster in the otherwise unassuming constellation Cancer. It is tucked between the stars Delta and Gamma Cancri, which form the eyes of the crab. With the naked eye it appears as a fuzzy patch in the sky, but binoculars or a telescope reveal numerous stars.
This image is one of the first taken with my new SharpStar 150mm f/2.8 Hyperbolic Newtonian Telescope (HNT) with a 420mm focal length. This is a stack of 11 x 180s exposures with a Canon 6D, processed in PixInsight.
A proper experimental night tonight using a tool Chris very kindly gave to me. This is a combination of camera rotation, zoom and focus pulling, lens cap trick and back-lit cardboard.
This just grew from aimlessly trying out different techniques until I found an effect I could work into another image.
Straight out of the camera....and into Lightroom for some minor adjustments.
This is number 228 of my 366.
The nebula Messier 78 is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalogue of comet-like objects that same year. It is located approximately 1,600 light years distant from Earth.
"Among the . . . particles responsible for the scattering (the reflected star light illuminating these structures) are carbon compounds (e. g. diamond dust) and compounds of other elements such as iron and nickel. The latter two are often aligned with the galactic magnetic field and cause the scattered light to be slightly polarized."

*Nebulosa Iris y fantasmas en Cefeo.*
La nebulosa Iris, a la izquiera, también conocida como NGC 7023 y Caldwell 4, es una nebulosa de reflexión azul brillante en la constelación de Cefeo. NGC 7023 es en realidad el grupo de estrellas dentro de la nebulosa LBN 487.
A la derecha se pueden observar unas nubes moleculares de polvo intelestelar con curiosas formas fantasmagóricas, la inferior, mas brillante, es conocida cómo el fantasma de la antorcha, vdB 141 o Sh2-136.
La nebulosa iris se encuentra a 1.300 años luz y los fantasmas a 1.200 años luz, con un tamaño de unos 2 años luz aproximadamente.

Quickie tonight as I'm done after a hard week at work. Thanks to Lauren for being the hand model.
Exact same principle and procedure as last night.
This is number 246 of my 366.
Explanation: This pretty, open cluster of stars, M34, is about the size of the Full Moon on the sky. Easy to appreciate in small telescopes, it lies some 1,800 light-years away in the constellation Perseus. At that distance, M34 physically spans about 15 light-years. Formed at the same time from the same cloud of dust and gas, all the stars of M34 are about 200 million years young. But like any open star cluster orbiting in the plane of our galaxy, M34 will eventually disperse as it experiences gravitational tides and encounters with the Milky Way's interstellar clouds and other stars. Over four billion years ago, our own Sun was likely formed in a similar open star cluster.
This picture was photographed March, 09, 2015 in Khlepcha observatory, Ukraine.

Really beautiful object catalogued as 881 on the Lynds' Catalogue of Dark Nebulae.
It's one of the jewels that you could find on gamma Cygni nebula, on SADR region of Cygnus, one of my favorites regions of the sky.
"A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds." (wiki)
It was necessary to integrate more than 70 hours to show all faint and nice details on the estructure.
Here was captured using the more natural palette, please also check my HSO palette on this link:
