In addition to the cluster and some mini-galaxies (Mini in apparent size, not absolute. 😅), I believe I managed to capture Galactic Cirrus (IFN, Integrated Flux Nebula), on the bottom left! Super tenuous, but I think it's there.

So, do you prefer Omega Centauri or the Hercules Cluster?

El complejo de nubes de Rho Ophiuco se encuentra en el borde de las constelaciones de Ophiuco y Escorpio, es una de las zonas más coloridas del cielo de verano en el hemisferio norte para los astrofotógrafos. Se encuentra a unos 400 años luz de la Tierra. La estrella principal del complejo es la la supergigante Antares con su colorido naranja cerca del centro de la imagen. a su derecha se encuentra el cumulo estelar M4, este cumulo estelar nos esta en el mismo plano ya que se encuentra a 7000 años luz.

Si nos movemos hacia la derecha en sentido contrario a las agujas del reloj, encontramos una nebulosa de emisión, la Pink nebula, con su estrella Al niyat que emite radiación ultravioleta que excita los átomos de hidrogeno de la nebulosa dando su característico color rosado.

Siguiendo hacia arriba nos encontramos con nubes de polvo marrón. A la izquierda se encuentra el complejo nebular de Rho Ophiuco con su característica coloración azul formado por doa nebulosas , la grande arriba IC 6404 y la pequeña abajo IC 6403. Son nebulosas de reflexión. La más grande IC 4604 está iluminada por un sistema múltiple de estrellas azules gigantes conocidas como Rho Ophiuchi. Esta zona es un vivero estelar. Si seguimos hacia la izquierda veremos unos caminos oscuros de polvo y gas, debajo y volviendo Antares tenemos una nebulosa amarilla de reflexión y debajo otra nebulosa de emisión roja.

The Rho Ophiuco cloud complex is located on the edge of the constellations Ophiuco and Scorpio, it is one of the most colorful areas of the summer sky in the Northern Hemisphere for astrophotographers. It is located about 400 light years from Earth. The main star of the complex is the supergiant Antares with its orange coloring near the center of the image. To its right is the star cluster M4, this star cluster is not in the same plane as it is 7000 light years away.

If we move to the right in an anti-clockwise direction, we find an emission nebula, the Pink nebula, with its star Al niyat that emits ultraviolet radiation that excites the hydrogen atoms of the nebula giving its characteristic pink color.

Continuing up we find clouds of brown dust. On the left is the Rho Ophiuco nebular complex with its characteristic blue coloration made up of two nebulae, the large above IC 6404 and the small below IC 6403. They are reflection nebulae. The larger IC 4604 is illuminated by a multiple system of giant blue stars known as Rho Ophiuchi. This area is a stellar nursery. If we continue to the left we will see some dark paths of dust and gas, below and returning Antares we have a yellow reflection nebula and below another red emission nebula.

You can see these annotated structures in a photo attached here on flickr.

Cuando las vi a la mañana casi me tiro por la ventana... Pero al final, al apilar las tomas y aplicarle un antiruido en el propio PixInsight y después en PS pues no ha quedado tan mal....

La nebulosa del Velo es una nube de gas caliente e ionizado. Es la parte visible del Bucle de Cygnus, también conocido como fuente de radio W78, o Sharpless 103. Es una nebulosa muy extensa y se suele dividir en tres grandes áreas: El velo Oriental: (Caldwell 34) que se halla cerca de la estrella 52 Cygni. El velo occidental (Caldwell 33), y el Triángulo de Pickering Wisp. Se trata del remanente de una supernova relativamente débil en la constelación del Cisne.

La supernova que le dio origen explotó hace entre 5000 y 8000 años, y los restos se han expandido desde entonces para cubrir un área de aproximadamente 3x3 grados, cerca de 6 veces el diámetro de la luna llena. La distancia a la nebulosa no se conoce con precisión, pero el Far Ultraviolet Spectroscopic Explorer (FUSE) estima la misma en unos 1470 años luz. Fue descubierta el 5 de septiembre de 1784 por William Herschel.

El telescopio espacial Hubble capturó imágenes de la nebulosa. El análisis de las emisiones de la nebulosa parece indicar la presencia de oxígeno, azufre e hidrógeno.

A mayor resolución, algunas partes de la imagen aparecen como filamentos. La explicación estándar es que las ondas de choque son tan delgadas, que el depósito de gases sólo es visible cuando se ve exactamente de canto, dando el depósito de la aparición de un filamento. Ondulaciones en la superficie de la estructura conducen a múltiples imágenes filamentosas, que parecen estar relacionados entre sí.

La nebulosa es conocida entre los astrónomos por ser difícil de ver visualmente, a pesar de tener una magnitud global de 7. Sin embargo, con un telescopio, utilizando un filtro OIII (un filtro de aislamiento de la longitud de onda de la luz de oxígeno doblemente ionizado), permitirá a un observador ver la nebulosa con claridad, ya que casi toda la luz de esta nebulosa es emitida en esta longitud de onda. Con un telescopio de 8 pulgadas (200 mm de diámetro) equipado con un filtro OIII, permite ver fácilmente el delicado encaje que se aprecia en las fotografías. Este objeto es uno de los mayores y más brillantes emisores de rayos X.

Los segmentos más brillantes de la nebulosa se enumeran en el Nuevo Catálogo General (NGC) con las designaciones de NGC 6960, 6979, 6992 y 6995. El segmento más fácil de encontrar es 6960, que corre a través de la estrella 52 Cygni. NGC 6979 (la parte central del complejo) es el Triángulo de Pickering. Éste segmento de la nebulosa fue descubierto fotográficamente por William Fleming, pero el crédito se le otorgó a su supervisor (Edward Pickering) por lo cual se le denominó de esa manera.

NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster.

All of the objects are located in the Monoceros constellation, near Orion and are located about 2300 light-years from Earth.

Here is a view of the Crescent Nebula (NGC 6888, Sharpless 105) located in the constellation Cygnus. The Crescent Nebula is about 5,000 light years away from Earth and was formed by the central star shedding its outer layers. According to NASA, “Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion”. This is a re-processed image using several new PixInsight plugins called StarXTerminator and BlurXTerminator.

IC 2944 – Running Chicken Nebula (English Below)

Famosa nebulosa de emissão localizada no hemisfério sul.

Nesta imagem ela está sendo apresentada em cores falsas devido ao uso de filtros de banda estreita.

Muitos observam a forma de uma galinha correndo (fugitiva), por isso é conhecida também como Running Chicken Nebula.

Outros nomes em que ela é conhecida: Nebulosa Lambda Centauri e IC 2944

Está localizada a cerca de 6500 anos luz de distância na constelação de Centauro.

Os glóbulos escuros no centro da imagem, são chamados de Glóbulos de Thackeray, devido ao astrônomo sul africano Andrew David Thackeray que observou pela primeira vez em 1950. Essas regiões quando observadas com telescópios infravermelhos, revelam um berçario estelar.

Uma região de formação de estrelas.

Uma olhada mais detalhada, mostra que o glóbulo escuro maior, é formado por duas partes separadas, porém sobrepostas, dando a impressão de ser um só. Essas duas núvens juntas tem a massa equivalente a 15 vezes a massa do sol.

Os glóbulos parecem estar fraturados devido ao ambiente hostil em que estão inseridos, já que

as estrelas jovens e quentes que energizam e aquecem a nebulosa de emissão, emitem intensa radiação ultravioleta, inclusive, em última instância, os glóbulos podem ser dissipados por esse ambiente, antes mesmo de se contrairem e tornarem-se estrelas massivas.

Essa notável paisagem celeste se espalha por um campo estimado de 60 mil anos luz.

IC 2944 - Running Chicken Nebula

Famous emission nebula located in the southern hemisphere.

In this image it is being rendered in false colors due to the use of narrowband filters.

Many observe the shape of a running chicken (fugitive), so it is also known as Running Chicken Nebula.

Other names in which it is known: Lambda Centauri Nebula and IC 2944

It is located about 6500 light-years away in the constellation Centaurus.

The dark globules in the center of the image are called Thackeray's globules, due to the South African astronomer Andrew David Thackeray who first observed them in 1950. These regions when viewed with infrared telescopes reveal a stellar nursery.

A region of star formation.

A closer look shows that the larger dark globule is formed by two separate but overlapping parts, giving the impression of being one. These two clouds together have the mass equivalent to 15 times the mass of the sun.

The Globules appear to be fractured due to the hostile environment in which they are inserted, since the young, hot stars that energize and heat the emission nebula emit intense ultraviolet radiation, including, ultimately, the globules can be dissipated by this environment before they even contract and become massive stars.

This remarkable celestial landscape spreads over an estimated 60,000 light years.

NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. This 20×30 arcmin sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star, B 1. It collectively forms Sh2-184, spanning over a larger area of 40 arcmin. A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies 2.82±0.20 kpc. (9200 ly.) from us. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

Edward Emerson Barnard discovered the nebula in August 1883, describing it as "a large faint nebula, very diffuse." Multiple star 'B 1' or β 1 was later discovered by S. W. Burnham, whose bright component is identified as the highly luminous O6 spectral class star, HD 5005 or HIP 4121. It consists of an 8th-magnitude primary with four companions at distances between 1.4 and 15.7 arcsec. There has been no appreciable change in this quintuple system since the first measures were made in 1875.

A widefield HaOIII Narrowband Bi-Color image of the Eagle Nebula, with the "Pillars of Creation" visible in the Nebula. The Eagle Nebula is catalogued as Messier 16, M16, or NGC 6611, and also known as the Star Queen Nebula and The Spire. M16 is a young open cluster of stars in the constellation Serpens.

The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula in the north-eastern part is approximately 9.5 light-years or about 90 trillion kilometers long.

Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" photographed by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the Pillars of Creation.

The cluster associated with the nebula has approximately 8100 stars, which are mostly concentrated in a gap in the molecular cloud to the north-west of the Pillars.

About this image:

Photographing in specific (or narrow) wavelengths of light creates a very different type of image. The Hydrogen dust and gas (the most basic and abundant element in the Universe), emits in the Red part of the spectrum, and the doubly ionized Oxygen emits in the Blue part of the spectrum. This HaOIII Bi-Color technique is a great way to show the Hydrogen and doubly ionized Oxygen in a DSO (Deep Sky Object).

Part of a dark expanse that splits the crowded plane of our Milky Way galaxy, the Aquila Rift arcs through the northern hemisphere's summer skies near bright star Altair and the Summer Triangle. In silhouette against the Milky Way's faint starlight, its dusty molecular clouds likely contain raw material to form hundreds of thousands of stars and astronomers eagerly search the clouds for telltale signs of star birth. This telescopic image looks toward the region at a fragmented Aquila dark cloud complex identified as LDN 673. The dark clouds in Aquila are estimated to be some 600 light-years away. At that distance, this field of view spans about 290 light-years. [Text adapted from APOD]

Ic434

IC 434 is an emission nebula visible in the constellation of Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.

This is an H II region that extends south of Alnitak, on the southwestern edge of the large Orion B cloud; it has a very elongated shape in a north-south direction and receives the ionizing wind directly from the star σ Orionis, a bright member of the large Orion OB1 association.

The nebula reaches 70' in length and is easily shown in long exposure photos or CCD images, although its thickness is only a few arc minutes.

The temperature of the region was measured using various methodologies and exploiting various radiation ratios, initially obtaining values ​​between 8000 K and 7600 K;

subsequently this value was reduced to 3360 K and even less depending on the map taken as reference. A study on electronic temperature conducted in 1992 instead provided a value more similar to the previous ones, which is around 6000 K.

Just going through some old data and I came across this one that I captured on NOV 9 of 2015 using an Astro-Tech AT65 Quad Astrograph that had been returned to the manufacturer as faulty and then sent to me for troubleshooting, this is only 3 x 180 seconds each LRGB and using Optolong Filters. I found no issues with it in fact I was very impressed with the optics, a perfect combination using the very sensitive QHY23 Mono CCD

The Double Cluster in the constellation of Perseus lie very close to us at only 7500 light years and is one of the most popular targets in the Night Sky for amateur Astronomers and imagers, a perfect object for testing a refractor.
