De SkySafari Plus: el cúmulo M45 es uno de los objetos más prominente en el cielo nocturno, que dio lugar a leyendas en la mitología antigua. Se mencionan en la Iliada y la Odisea, la Biblia, por los persas, los japoneses que lo denominaron Subaru, de donde vino el nombre de la marca de automóviles. El nombre de Pléyades viene de su madre mitológica, Pléyone, y el nombre de las siete estrellas más brillante proviene de las siete hermanas de la mitología griega.
A simple vista pueden verse las seis o siete estrellas más brillantes. Alrededor de las estrellas están las nebulosas de color azul, que se produce al reflejar las estrellas más brillantes del cúmulo, lo que se confirma al ver que los espectros de las estrellas y las nebulosas coinciden.
El cúmulo de estrellas solamente está pasando a través de la nebulosa y difieren en su origen. En total, está compuesto por más de 1000 estrellas. Se estima que se originó hace unos 100 millones de años. Las estrellas rotan con velocidades entre 150 y 300 km/s, algo común para estrellas jóvenes de la clase B.
Con el tiempo, el cúmulo será visible cerca de la constelación de Orión, después de lo que tardará unos 250 millones de años en dispersarse.

Taken 6 to 10 August 2022 on consecutive nights, a wide field of the Cygnus region containing The Tulip, Crescent, Soap Bubble, WR 134 and Sh2-104 Nebulae. This image comprises 18hrs of capture of narrowband Sii, Ha, and Oiii plus LRGB for the stars. So many elements in this image to bring out in processing, starting from scratch 5 times now, but this is the finished version for now anyway. Whilst there are many individual nebulae in this image, a few of the more identifiable due to structure are listed below.
The Tulip Nebula – Sh2-101 The emission from the Tulip Nebula is powered by ultraviolet radiation of the hot young star HD 227018. The O6.5III class star belongs to the Cygnus OB3 association and has a visual magnitude of 9.02. In images, it can be seen near the nebula’s centre.
The Soap Bubble Nebula, or PN G75 is a planetary nebula in the constellation Cygnus, near the Crescent Nebula (NGC 6888). It was discovered by amateur astronomer Dave Jurasevich using an Astro-Physics 160 mm refractor telescope with which he imaged the nebula on June 19, 2007 and on July 6, 2008. Can you see it? It is underneath the Crescent Nebula, a little to the left in this image.
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun.
NGC 6888, the Crescent Nebula, is about 25 light-years across blown by winds from its central, bright, massive star. The oxygen atoms produce the blue hue that seems to enshroud the detailed folds and filaments. Visible within the nebula, NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years.
Sh2-104 is a very faint emission nebula in the constellation Cygnus. This is located due east of the popular Crescent Nebula. Sh2-104 is viewed by professional astronomers as a good illustration of the "collect and collapse" model of star formation triggered by the rapid expansion of a Helium II region.

De Sky Safari:
La nebulosa Cabeza de Caballo (Horse head nebula), conocida también como Barnard 33, es una pequeña nebulosa oscura que contrasta contra la nebulosa roja de emisión IC 434.
Fue registrada por primera vez en una fotografía en el Observatorio de Harvard College en 1888 y fue incluida en el catálogo de Barnard en 1919. Dentro de la “cabeza” existen manchas rojas que son protoestrellas en proceso de formación.
La región entera está iluminada por la estrella brillante OB Sigma Orionis, que es responsable de la ionización del hidrógeno, produciendo su característico color rojizo.
A la izquierda de la imagen se ve la nebulosa de la Llama (NGC 2024), que está a unos 900 años luz, es decir algo más de la mitad de la distancia a la que se encuentra la cabeza de caballo. En ella se aprecian bandas oscuras. Está ionizada por la estrella Alnitak, que es la estrella más brillante de la imagen y la más oriental del cinturón de Orión. Se estima que unas 10 estrellas están dentro de la nebulosa.
En la foto también se pueden ver otros objetos como cuatro galaxias muy pequeñas (PGC) y diferentes nebulosas adicionales (IC y NGC).

This is the view I was after when the USB plug broke on the camera March last year. This proved to be a marathon getting images as the mount threw up a curveball and at this stage still not sure if I have found the answer to the problem.
This will be my last photo for a very long time as I do a huge panorama of the Milky way of some 40 odd shots. Enjoy it.

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..

A reboot with new data of a target I have previously looked at.
The previous target was pretty but I felt it lacked all the detail the target had to offer so added an additional 30 HA subs from the RH to help realise that. Small percentages but makes a lot of difference when reviewed in detail.
It also allowed me to resolve the ICC mismatch issues my PC suffered after recent updates which caused all sorts of issues on my last image!
NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100000 times that of the Sun.

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.

"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."

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

Or, is the Milky Way a fire?
Not really -- it's dark matter, gas and dust, and stars. I hadn't even realized the alignment here when I set up the shot, but after it appeared on the camera monitor, I knew I had to run with it. The trees and cabin are a single shot with the settings shown. The sky is a stack of 10 shots with those settings. The sky images were preprocessed with dark frames, registered, and stacked in PixInsight. Colors were balanced in PixInsight before bringing both pics over to Photoshop to composite them. Then, it was the usual playing with levels and curves to get the Milky Way to pop well.
