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!

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.

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.

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.

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.
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:

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 :-)

Questo target riprende la nebulosa NGC 6820, nota anche con le sigle Sh2-86 e LBN 135, all'interno della quale si trova l'ammasso aperto NGC 6823.
Avevo visto per caso questa nebulosa sul web e mi aveva attratto non solo la sua struttura ma anche il complesso di nebulose ad emissione, riflessione ed oscure che la circonda. Non ho fatto però i conti che l'immagine che avevo visto aveva un'integrazione di ben 48h. Avevo programmato l'acquisizione di una congrua integrazione in banda larga ma purtroppo sono ruscito ad acquisirne solo 3,5h. Speravo che acquisendo oltre 14h in banda stretta avrei potuto compensare la carenza della banda larga, ma così non è stato. E' stata una delle mie più complicate elaborazioni. Forse perchè le condizioni del cielo durante alcune sessioni non erano favorevoli, forse perchè la nebulosa è di per sè molto debole ma credo che un buon risultato si sarebbe ottenuto facilmente con molta acquisizione in banda larga.
Eppure penso che nel complesso la fatica elaborativa abbia dato i suoi frutti con questa immagine abbellita dal colore delle stelle acquisite in banda larga.

This target captures the nebula NGC 6820, also known as Sh2-86 and LBN 135, within which lies the open cluster NGC 6823.
I had accidentally seen this nebula on the web and was intrigued not only by its structure but also by the complex of emission, reflection, and dark nebulae surrounding it. However, I hadn't noticed that the image I had seen had an integration of a full 48 hours. I had planned to acquire a suitable broadband integration, but unfortunately I only managed to acquire 3.5 hours. I hoped that by acquiring more than 14 hours in narrowband I could compensate for the lack of broadband, but that wasn't the case. It was one of my most complicated processings. Perhaps because the sky conditions during some sessions weren't favorable, perhaps because the nebula itself is very faint, but I believe a good result would have been easily achieved with extensive broadband acquisition.
Yet I think that overall the processing effort has paid off with this image embellished by the color of the stars acquired in broadband.

Explanation: To the eye, this cosmic composition nicely balances the Bubble Nebula at the lower left with open star cluster M52 above it and to the right. The pair would be lopsided on other scales, though. Embedded in a complex of interstellar dust and gas and blown by the winds from a single, massive O-type star, the Bubble Nebula, also known as NGC 7635, is a mere 10 light-years wide. On the other hand, M52 is a rich open cluster of around a thousand stars. The cluster is about 25 light-years across. Seen toward the northern boundary of Cassiopeia, distance estimates for the Bubble Nebula and associated cloud complex are around 11,000 light-years, while star cluster M52 lies nearly 5,000 light-years away. The wide telescopic field of view spans about one degrees on the sky or two times the apparent size of the Full Moon. (Text: apod.nasa.gov/apod/ap131008.html )

In this picture I discover an planetary nebula pKjPn8 (also known as PN G112.5-00.1) is a very unusual bipolar planetary nebula. Its complex structure is the result of irregular ejections of gas in different directions. (www.noao.edu/image_gallery/html/im1089.html)

Another image from the Hullbull Remote Space Telescope. Later in the sequence of the same mini supernova, one of many, shown in previous images and a much wider field of view. The timing is past the stellar collapse and development and disappearance of the black hole. All that remains are energized molecular clouds, emission nebula of elements seeded prior to initiation of dimensional oscillation. The supernova shock wave is clearly visible. The nearby binary star system should be visible to the upper left, but gravitational lensing and distortion of light in the turbulence of the shock wave have caused a diffuse yellow light. A gravitationally lensed nearby light show supernova is visible to the lower left. Images of the black hole consuming matter created by the controlled Big Bang are still being processed.
Image from early in the light show heralding the opening of Metropolis 1, a new City of Light created some thousand light years away and presented by the intrepid space-time traveling photographer Alan Jaras. This image is from a large set of high-speed photos documenting the first mini-big bangs created by the impressive dimensional oscillator.
Iteration on the Sharpless catalogue of faint nebulae.
It's not a common object, and here is the close up. Very faint and difficult. I am really proud of it :D
Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.
The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.
This nebula is about 2/3 the diameter of the full moon.

The Iris Nebula or NGC 7023, is a reflection nebula, its color comes from the light of its central star, which lies in the constellation Cepheus. You can find it nearish to the North Star. It is located ~1,400 light-years away from Earth, and its gasses stretch ~6 light-years across.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I then mounted my a7RIII and adapted Nikon 500mm f/4 P Ai-s lens to the top rail of my scope. I used SharpCap to achieve "excellent" polar alignment. I shot ISO 3200, f/4 and 181" exposures. Image frames were stacked and integrated and processed in PixInsight using: STF, Cropping, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator and then the DSO was separated from the stars, and both files processed and stretched separately and then recombined using PixelMath. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping to the final image.
Explanation: Scanning the skies for galaxies, Canadian astronomer Paul Hickson and colleagues identified some 100 compact groups of galaxies, now appropriately called Hickson Compact Groups. The four prominent galaxies seen in this intriguing telescopic skyscape are one such group, Hickson 44, about 100 million light-years distant toward the constellation Leo. The two spiral galaxies in the center of the image are edge-on NGC 3190 with its distinctive, warped dust lanes, and S-shaped NGC 3187. Along with the bright elliptical, NGC 3193 at thebottom, they are also known as Arp 316. The spiral in the upper right corner is NGC 3185, the 4th member of the Hickson group. Like other galaxies in Hickson groups, these show signs of distortion and enhanced star formation, evidence of a gravitational tug of war that will eventually result in galaxy mergers on a cosmic timescale. The merger process is now understood to be a normal part of the evolution of galaxies, including our own Milky Way. For scale, NGC 3190 is about 75,000 light-years across at the estimated distance of Hickson 44. (text: apod.nasa.gov/apod/ap110829.html )

NGC 300 is a nearby spiral galaxy located in the Sculptor Group, roughly six million light-years from Earth. Viewed almost face-on, its delicate spiral arms reveal intricate dust lanes, glowing star-forming regions, and a rich population of young blue stars mixed with older stellar light. Its proximity and clarity make NGC 300 a favorite target for studying galactic structure and stellar evolution, offering a striking reminder of the quiet elegance found beyond our own Milky Way.

Took the new 12-inch Meade LX200 out for a nice drive in the cosmos over the last few nights and put it through its paces.
The mount is still in need of some work but this scope is amazing!
The dark nebulae in this photo are part of a complex of Bok globules inside of the Rosette Nebula, NGC 2237. Bok Globules are dense opaque clouds of dust and gas, some of which are condensing under gravitational attraction to form stars and planets.
The Rosette nebula is located in the constellation of Monoceros approximately 6000 light years away.

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.

*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.

I photographed this handsome nebula about 2 weeks ago during a nearly full moon with the Optolong L-eXtreme filter.
NGC 7380 is a "must-shoot" object in Cepheus in my books. It's a fantastic target to try with a one-shot-color camera or DSLR, but a light pollution filter with narrow bandpasses will help keep those stars from taking over.

One of those moments, when results are better than it was planned ! Quite an amazing feeling. It's like when trying payes off and you feel relaxed - after merging 6 shots, I sat smiling :)
Shot taken in Georgia, Ertatsminda. It's several kms away from Kaspi.

Explanation: Why do many galaxies appear as spirals? A striking example is M101, shown above, whose relatively close distance of about 27 million light years allows it to be studied in some detail. Recent evidence indicates that a close gravitational interaction with a neighboring galaxy created waves of high mass and condensed gas which continue to orbit the galaxy center. These waves compress existing gas and cause star formation. One result is that M101, also called the Pinwheel Galaxy, has several extremely bright star-forming regions (called HII regions) spread across its spiral arms. M101 is so large that its immense gravity distorts smaller nearby galaxies. (text from apod.nasa.gov/apod/ap090414.html)

This is a tight crop of an image of the Weinberger planetary nebula. I captured the outstanding OIII data for the planetary nebula last night. It was interesting to see the levels of oxygen emission from the PN with the new data added. OIII x 14 x18 , Ha 17x 1800 and SII 17x 1800. This would make an excellent target for longer focal length optics. May be next time round.
