This scene features a trio of interacting galaxies found in the constellation of Virgo, being some 70-90 million light years away from Earth. The largest galaxy in the group is NGC 5566, which is a barred spiral galaxy stretching nearly 150,000 light years in diameter. Having widely sweeping spiral arms, with dark dusty lanes, these arms are speckled with new star forming regions throughout. The elongated galaxy to the left of NGC 5566 is the heavily distorted NGC5560. You can just see faint dusty interconnections between NGC 5560 and NGC 5566, providing us some clues that these are in fact interacting. The lower blueish galaxy NGC5569 does not appear to be disturbed, and maybe placed slightly in the foreground.
In the darkness of the surrounding space, the speckled background indicates a sea of background objects, all being in the significant distance.

A hidden treasure in Orion's Belt. I was only able to get ~48 minutes of integration time. I hope the next time I can gather more data. This was my first time gathering data for these objects. This data was taken on 12.16.2020. When I first attempted to process it I became frustrated. I attempted again with PixInsight and it has made me want to shoot it again with more time.

My mount was polar aligned with SharpCap 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 1600, f/5.6 and 195" exposures. I brought the lights/darks/flats/bias frames into PixInsight for stacking and aligning and then used: 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..

"Messier 42 (M42), the famous Orion Nebula, is an emission-reflection nebula located in the constellation Orion, the Hunter. With an apparent magnitude of 4.0, the Orion Nebula is one of the brightest nebulae in the sky and is visible to the naked eye. It lies at a distance of 1,344 light years from Earth and is the nearest stellar nursery to Earth.
The Orion Nebula is very easy to find as it is located just below Orion’s Belt, a prominent asterism in the winter sky. The nebula appears as the fuzzy middle star in Orion’s Sword, which is formed by a vertical row of three stars (i.e. two stars and M42) south of Orion’s Belt. The nebula can easily be seen in binoculars and small telescopes. Covering more than a degree of apparent sky, the nebula appears over four times the size of the full Moon.
Small telescopes at higher magnifications will reveal the four brightest stars in the Trapezium Cluster, an open cluster of young, hot, massive stars that were formed within the Orion Nebula. The four stars form a trapezoidal shape and energize the surrounding nebulosity."

The comet has not been visible from my yard in a Bortle 7 suburb of NYC, even with binoculars. But as is often the case, astrophotography reveals the invisible. There were enough passing clouds and haze to leave me unsure if this would work at all, but 3 hours of data and patience with PixInsight seems to have done the trick.

This morning I was able to see the comet naked eye once I knew exactly where to look. It was brighter than M13 and I'd estimate its brightness as +5.4 magnitude. Viewed near Oracle, Arizona under Bortle 4, sky transparency 10/10, temperature 23F, RH 75%, no winds. Elevation 3575 feet. Coldest morning so far this winter!
Tech Specs: Nikon d7100, 180mm f/2.8 @ f/2.8, iso 2200, exp 30x105s, raw, cropped, PixInsight (new Comet Alignment routine that enables fixed comet and fixed stars). Comet's anti-tail is still obvious. The comet was moving 8.7 arcmins/hour or the moon's diameter in about 3.5 hours!
Looks like I will have great clear mornings for daily updates this week. The comet should be a more obvious naked eye object in dark moonless skies for the next two weeks. The near full moon sets 30 minutes before twilight interferes on 2 Feb. The comet will be ~20 degrees above the northeast horizon on that date.

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0. Located just above the Orion Nebula is the Running Man Nebula.
This image was created from images I captured earlier this year but this time I used PixInsight and Lightroom to get the end result. PixInsight is an excellent piece of software but is complicated and an initial steep learning curve got me to this point. I need to try it on some of the other DSO targets I also captured earlier this year.

Sh2-290 es una nebulosa planetaria. A pesar de su nombre, este tipo de nebulosas no tiene relación con los planetas, sino que corresponde a la nebulosa que deja una estrella similar al sol llega a su fin al agotarse su combustible.
Tiene un diámetro de unos 23 años luz, lo que la hace una de las nebulosas planetarias más grandes observadas desde la tierra, y en la foto se ve de un tamaño similar al que tendría la luna. Al ser tan extensa pierde brillo y es la razón por la que es tan tenue (requirió casi 10 horas de exposición).
Está compuesta principalmente por hidrógeno (rojo) y oxígeno (azul). La estrella en el centro es una enana blanca, que es el remanente de la estrella que la originó.
En la imagen también se pueden ver otros objetos como 14 galaxias tenues (PGC).
Sh2-290 también se conoce como Abell 31 y ARO 135

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.

7000-7500 light-years distant in the constellation of Cassiopeia lie the emission nebulae colloquially known as the Heart and The Soul Nebulae. The gasses (mostly hydrogen) that comprise the nebulae are being ionized by the stars within the region and as a result, the gasses glow, much like a neon sign.
The pressures exerted upon the material by the stars nearby are causing the material to become compressed. When enough of the gas becomes highly compacted, it triggers the birth of new stars. In effect, this is a beautiful snapshot of a multimillion-year process of an enormous cloud of dust and gas transforming itself into new stars.

This is 12 shots(6x2) as the milky way rises in our Southern Skies as per the plan by Nina, This Is Not Seen North Of The Equator. This is halfway to where I want to get there is another panorama of 12 shots to go to get to the panorama I took last year. Each Panel is a night worth of shots then added to PtGui to get the panorama. There positively no edits on the stars this is the number that the camera can see.

I believe I'm one of the few who captured the Relativistic Jets so clearly with a Sky Bortle 5 in Brazil! I'm not trying to be better at anything in Astrophotography. My words are based on the photos I see of this object in my country! I thought it was important to capture enough data in H-Alpha to show the relativistic jets and praise the Galaxy Mergers!
