The great globular cluster in Hercules
With a small(?) galaxy NGC 6207 nearby (much farther away).
The reddish star nearby is Eta Herculis.
Taken with Orion 80mm Refractor on a Losmandy mount.
From SpaceTelescope.org, “NGC 7006 resides in the outskirts of the Milky Way. It is about 135,000 light-years away, five times the distance between the Sun and the center of the galaxy, and it is part of the galactic halo. This roughly spherical region of the Milky Way is made up of dark matter, gas and sparsely distributed stellar clusters.”

Júpiter y el Río lechoso.
En el centro de esta imagen se puede apreciar una “estrella” brillante de color blanco, resulta ser el planeta gigante gaseoso Júpiter, ubicada actualmente en la constelación de Ofiuco. A la izquierda lo acompaña la Via láctea, se le llamo así ya que al ojo desnudo se aprecia como una mancha blanca que atraviesa el cielo nocturno ya que nuestros ojos no tienen la capacidad de ver los colores de estas estructuras que están a miles de años luz, por eso, a través de la cámara se pueden desfigurar los colores reales de estas estructuras. El color amarillo-anaranjado son cientos de miles de estrellas viejas ubicadas hacia el centro galáctico, las nebulosas negras son nubes densas que se encuentran entre nosotros y el centro galáctico, al ser tan densas bloquean la luz que se encuentra detrás de estas nubes, los colores rojizos y rosados son principalmente regiones de formación estelar, regiones Hll, donde las estrellas masivas y brillantes ionizan el gas circundante haciéndolas brillar de estos colores.

This cluster (M5 or NGC 5904) is too big for the setup I've been using a lot recently, so I shot it with the Hyperstar at a focal length of 535 mm instead of the 0.63x reducer at 1530 mm. I just got a set of 2" Optolong LRGB filters from Starizona to use with the Hyperstar and Atik 414-EX camera, and this was my first target.

Almost like snowflakes, the stars of the globular cluster NGC 6441 sparkle peacefully in the night sky, about 13 000 light-years from the Milky Way’s galactic centre. Like snowflakes, the exact number of stars in such a cluster is difficult to discern. It is estimated that together the stars weigh 1.6 million times the mass of the Sun, making NGC 6441 one of the most massive and luminous globular clusters in the Milky Way.
NGC 6441 is host to four pulsars that each complete a single rotation in a few milliseconds. Also hidden within this cluster is JaFu 2, a planetary nebula. Despite its name, this has little to do with planets. A phase in the evolution of intermediate-mass stars, planetary nebulae last for only a few tens of thousands of years, the blink of an eye on astronomical timescales.
There are about 150 known globular clusters in the Milky Way. Globular clusters contain some of the first stars to be produced in a galaxy, but the details of their origins and evolution still elude astronomers.

Here is a view of the most distant globular cluster in the Milky Way, NGC 2419, some have postulated that this may be an extra-galactic object. I have seen distances listed as high as 285,000 light-years away from Earth. It appears small and dim, but it is actually very large and very bright (if it was a bit closer to us), there are estimates of 300-400 million solar masses in this cluster.
You can also make out the galaxy NGC 2424, a barred spiral galaxy with a magnitude of 12.6. The view is dominated by the red giant star HD61294 in the lower right, magnitude 5.75, and 41 times larger than our Sun.

Messier 22 globular cluster

J2000 RA 18h 36m 23.94s Dec –23° 54′ 17.1″
Messier 22 (NGC 6656) is an elliptical globular cluster in Sagittarius, near the Galactic bulge region. It is one of the brightest globulars visible in the night sky and one of the nearer to Earth at a distance of about 10,600 light-years. It spans 32' on the sky which translates to a spatial real diameter of 99 ± 9 light-years.
It was one of the first globular clusters to be carefully studied first by Harlow Shapley in 1930.
M22 is very unusual in that it is one of only four globulars (the others being M15, NGC 6441 and Palomar 6) that are known to contain a planetary nebula.
Travelers to the southern hemisphere should make an effort to see the Southern Cross (Crux), an asterism used by navigators in the absence of a south pole star. As a circumpolar constellation, Crux is usually above the horizon all night long. See embedded notes for identifications.
Near it is Alpha Centauri, a triple star system whose minor member Proxima Centauri is the closest star to the sun (4.246 light-years).
Not having a tripod, I balanced my camera on an object and used the hat trick (cover lens with a hat when opening the shutter, then remove it quickly).
A cosmic snowball of around 150000 stars held together by their own gravity. The remnant of a cluster in a small galaxy orbiting the Milky Way. Most of its stars have been lost to the stronger pull of our Galaxy so just this tight core remains.
Because its members are so tightly packed together, it has a density classification of II – which is reserved for clusters that are particularly rich and compact.
There has been speculation about a dust channel (running from 3 o'clock down to 6 o'clock in this image) caused by dust thrown off from red giant stars in the cluster. Latest measurements suggest this is just asymmetry due to flattening of the "globe" from rotation of the cluster just like Jupiter and the Sun are flattened at their poles.

[From Wikipedia] NGC 5634 is a globular cluster in the constellation Virgo, located about 82,000 light years away. NGC 5634 has an apparent magnitude of about 10. Its Shapley–Sawyer Concentration Class is IV, meaning the cluster shows intermediate rich concentrations with stars in the 19th magnitude. There is also a bright orange giant, HD 127119, about 1.3 arcminutes away from the cluster.
NGC 5634 was likely a member of the Sagittarius Dwarf Spheroidal Galaxy. The galaxy itself is being pulled apart by tidal forces from the Milky Way, similar to how NGC 5634 was pulled from the Dwarf Spheroidal Galaxy.

J2000 RA 16h 41m 41.24s Dec +36° 27′ 35.5″
Messier 13 (M13), or NGC 6205, is a globular cluster of about 300,000 stars in Hercules, discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764.
M13 is about 145 light-years in diameter and at 25,100 light-years away from Earth.
The Arecibo message of 1974, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope towards M13 as an experiment in contacting potential extraterrestrial civilizations in the cluster.
This single frame image shows two different globular clusters as well as two different globular cluster types. Messier 53, on the bottom half of the image, is rated as a Class V globular cluster while NGC 5053 on the upper left edge of the image is a Class XI globular cluster. The Shipley-Sawyer Concentration Class contains a scale of twelve types of globular clusters based on the central density of stars, Class I being the densest and Class XII being the least dense. This image illustrates the visual difference pretty well.

Here is a Globular cluster known as 47 Tucanae NGC 104 this can be found just below the small Magellanic cloud we used a Zwo ASI120mc-s planetary camera on a Meade LX90 8 inch SCT telescope with tracking. This was taken on a 20-second exposer.
Here is another collage I made, this evening. Starting from the Top left is the Northern Pleiades, the top right is the Large Magellanic Cloud, the Middle photo is Orion's Nebula, the bottom left is the Southern Pleiades and the bottom right is the Small Magellanic cloud with the globular cluster called the 47 Tuc. The 47 tuc is the bright object just off to the bottom right of the small Magellanic cloud.
To get a better view, you may need to zoom in a little.
Messier 53 is a globular cluster in the constellation of Coma Berenices (Berenice’s Hair), it is one of the outmost globular clusters from the galactic center and it is 60,000 light years from Earth with a magnitude of 8.5 and an angular size of 12 arcminutes. It was discovered by Bode in 1775. I like the contrast between the globular cluster and the red and blue stars at about 10:00 in this image. North is right at about 4:00.

47 Tucanae (NGC 104) is a globular star cluster located about 13,000 light years away from Earth. The actual number of stars in this globular cluster is believed to be ~500,000 stars and the core is said to contain nearly 35,000! If planets could exist around the stars in the core of this cluster, one could only imagine what you would see in the day or night sky.

M53: is a Globular Cluster at a distance of 60,000 light years. It is one of the most distant of the outlying clusters. M53 contains over 250,000 stars.
Located in Coma Berenices constellation it was discovered by discovered by Johann Elert Bode in 1775.
NGC 5053: In the same frame and less than 1° from M53 is the less dense globular cluster NGC5053. While close to M53, NGC5053 wasn't discovered until 1784, 9 years later, when William Herschal cataloged it as VI-7. NGC 5053 is about 53,000 light years from Earth. This makes M53 and NGC 5053 relatively close neighbors.

The bright area left of the center of this image is the Small Sagittarius Star Cloud or M24. It is fairly large on the sky, so I decided to try shooting it with the Nikon D5100 instead of through the telescope. When I realized how many objects were nearby, it seemed like a good idea to expand the field of view.
There are 10 Messier objects present. These include four bright emission nebulae. From top to bottom, those are M16 (Eagle Nebula), M17 (Swan or Omega Nebula), M20 (Trifid Nebula), and M8 (Lagoon Nebula). Star clusters M25 and M23 are to the left and right, respectively, of the star cloud. Star cluster M21 is just above and left of the Trifid Nebula. M18 is a small star cluster between M17 and M24. In the lower left corner, globular cluster M28 is in view. There are many other NGC and IC objects present, along with dark clouds that represent areas dense with dust which blocks the view of background stars.
This is a stack of 47 60s exposures at a focal length of 90 mm and ISO 2000 from Mt. Pinos, CA. Dark, flat, and bias frames were applied in PixInsight, with registration, stacking, and additional processing in that program. Final touches in Photoshop.

Photos taken back in April, through veils of high clouds which frustrated me enough at the time that I gave up and didn't even bother with darks or flats. But still, I thought the holidays would be a good time to try it on PixInsight and DxO as an "exercise".

NGC 253, also known as Sculptor, is located about 11.5 million light years and is, after Andromeda (M31), the second largest galaxy closest to our Milky Way. It is the main member of a group that includes about 18 elements, including the dwarf galaxies Donatiello II/IX and NGC253-dw4 and NGC253-dw5.
NGC 288 is closer to us, just 28 thousand light years away.

This image from the NASA/ESA Hubble Space Telescope shows a globular cluster called NGC 1651. Like another recent globular cluster image, NGC 1651 is about 162,000 light-years away in the largest and brightest of the Milky Way’s satellite galaxies, the Large Magellanic Cloud (LMC). One notable feature of this image: the roughly 120-light-year diameter globular cluster nearly fills the entire frame. In contrast, other Hubble images feature entire galaxies – which can be tens or hundreds of millions of light-years in diameter – that also more or less fill the whole image.

En! The globular star cluster 47 Tucanae is a jewel of the southern sky.
Also known as NGC 104, it roams the halo of our Milky Way along with some 200 more globular stellar clusters.
It is the second brightest globular cluster (after Omega Centauri) seen from planet Earth. It is about 13,000 years old. Light and distance have been seen in a simple view of the small Magellanic Cloud in the constellation El Tucán.
The dense cluster is composed of several million stars in a volume of just 120 light years in diameter.
The giant red stars on the outskirts of the cluster are easy to distinguish as yellow stars in this clear telescopic portrait.
The globular cluster 47 is also home to the exotic binary X-ray star systems.

El cúmulo estelar globular 47 Tucanae es una joya del cielo del sur.
También conocido como NGC 104, vaga por el halo de nuestra Vía Láctea junto a unos 200 cúmulos estelares globulares más.
Es el segundo cúmulo globular más brillante (tras Omega Centauri) visto desde el planeta Tierra. Se trata de unos 13.000 años. La luz y la distancia se han visto en una vista simple de la pequeña Nube de Magallanes en la constelación de El Tucán.
El denso cúmulo está compuesto por varios millones de estrellas en un volumen de apenas 120 años luz de diámetro.
Las estrellas gigantes rojas de las afueras del cúmulo son fáciles de distinguir como estrellas amarillentas en este nítido retrato telescópico.
El cúmulo globular 47 también es hogar de los exóticos sistemas estelares binarios de rayos X.

Palomar 5 is a globular cluster and a member of the Palomar Globular Clusters group. It was discovered by Walter Baade in 1950, and independently found again by Albert George Wilson in 1955. There is a process of disruption acting on this cluster because of the gravitation of the Milky Way – in fact there are many stars leaving this cluster in the form of a stellar stream. The stream has a mass of 5000 solar masses and is 30,000 light years long. The cluster is currently about 60.6 kly from the Galactic Center. (Ref: Wikipedia)
This globular cluster has recently been found to harbor over 100 black holes in its center. You can read about here: earthsky.org/space/astronomers-find-100-black-holes-in-pa...
