The Man On the Vespa. A target I have never found a name for so I gave it one. Any one who has been to Italy and seen all the Vespa riders will know the sitting position. A few have heard me speak of this target but never really seen it quite like this. The Scope is in perfect focus why there is so much detail.
Narrow band and RGB stars in the Hubble pallet. I have paid homage to the Hubble pallet by not completely removing all the green. Add to the list of shot that make this up I even tried Sky flats so its a real long stack list.
At the very top of this shot is the outer Rim of the Tarantula Nebula one every one knows.
Enjoy the man like I have never seen before......and all the wispy details in the Background.

This is a dark nebula in the constellation Puppis. These nebulas were not discovered until the late '70s and were called cometary globules due to their long shape. This object appears as the hand of God reaching out and grabbing the galaxy PGC21338.

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.

Sh2-112 is a visibly emitting nebula in the constellation of Cygnus.
It is located in the northern part of the constellation, about 1.5 ° to WNW of the brilliant star Deneb.
It is a circular H II region of apparent size of about 15', crossed by a dark band on its western side oriented in a north-south direction. It is believed that the star responsible for its excitation is BD+45 3216; estimates of the distance of this star provide a value of 1740 parsec (about 5670 light years), which would place so Sh2-112 in a region of the Orion Arm particularly rich and physically very close to the great nebulous system of Cygnus X.

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.

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.

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 :-)

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!

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:

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!

The beautiful Sombrero Galaxy lying at 29.35 million light years from Earth.
Data obtained from telescope live. Image processing Steve Robinson 2023.
I am fascinated with faint supernova remnants. This one is particularity dim. It lies at the head of Cygnus the swan, on the border of Vulpecula. Located approximately 3,200 light years away.
Supernova remnants (SNR) are formed when a large star ends its life in a supernova explosion. About 300 of these remnants are currently known in our galaxy. One of the most famous remnants, the Veil Nebula, also located in the constellation of Cygnus. Although this is the most famous one in this constellation, it’s not the only SNR.
SNR G65.3+5.7 was discovered by Gull et al. (1977) during an OIII survey of the Milky Way. Some parts of this SNR were already catalogued by Stewart Sharpless in his SH2 catalog as SH2-91, SH2-94 and SH2-96, but they were not recognized as being part of a bigger structure at that time. The idea that they could be part of a larger SNR was postulated by Sidney van den Bergh in 1960, but it took until 1977 for this to be confirmed.

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."

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.
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.

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.
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.
