Edited Hubble Space Telescope image of the globular cluster M22. Dithered variant.
Original caption: This image shows the centre of the globular cluster Messier 22, also known as M22, as observed by the NASA/ESA Hubble Space Telescope. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 billion years old. Messier 22 is one of about 150 globular clusters in the Milky Way and at just 10 000 Â light-years away it is also one of the closest to Earth. It was discovered in 1665 by Abraham Ihle, making it one of the first globulars ever to be discovered. This is not so surprising as it is one of the brightest globular clusters visible from the northern hemisphere, located in the constellation of Sagittarius, close to the Galactic Bulge â the dense mass of stars at the centre of the Milky Way. The cluster has a diameter of about 70 light-years and, when looking from Earth, appears to take up a patch of sky the size of the full Moon. Despite its relative proximity to us, the light from the stars in the cluster is not as bright as it should be as it is dimmed by dust and gas located between us and the cluster. As they are leftovers from the early Universe, globular clusters are popular study objects for astronomers. M22 in particular has fascinating additional features: six planet-sized objects that are not orbiting a star have been detected in the cluster, it seems to host two black holes, and the cluster is one of only three ever found to host a planetary nebula â a short-lived gaseous shells ejected by massive stars at the ends of their lives.
Edited Hubble Space Telescope image of the globular cluster Messier 53.
Original caption: Thousands and thousands of brilliant stars make up this globular cluster, Messier 53, captured with crystal clarity in this image from the NASA/ESA Hubble Space Telescope. Bound tightly by gravity, the cluster is roughly spherical and becomes denser towards its heart. These enormous sparkling spheres are by no means rare, and over 150 exist in the Milky Way alone, including Messier 53. It lies on the outer edges of the galaxy, where many other globular clusters are found, almost equally distant from both the centre of our galaxy and the Sun. Although they are relatively common, the famous astronomer William Herschel, not at all known for his poetic nature, once described a globular cluster as “one of the most beautiful objects I remember to have seen in the heavens”, and it is clear to see why. Globular clusters are much older and larger than open clusters, meaning they are generally expected to contain more old red stars and fewer massive blue stars. But Messier 53 has surprised astronomers with its unusual number of a type of star called blue stragglers. These youngsters are rebelling against the theory of stellar evolution. All the stars in a globular cluster are expected to form around the same time, so they are expected follow a specific trend set by the age of the cluster and based on their mass. But blue stragglers don’t follow that rule; they appear to be brighter and more youthful than they have any right to be. Although their precise nature remains mysterious these unusual objects are probably formed by close encounters, possibly collisions, between stars in the crowded centres of globular clusters. This picture was put together from visible and infrared exposures taken with the Wide Field Channel of Hubble's Advanced Camera for Surveys.The field of view is approximately 3.4 arcminutes across.
Edited Hubble Space Telescope image of the globular cluster NGC 1805 in the Large Magellanic Cloud.
Original caption: Many colourful stars are packed close together in this image of the globular cluster NGC 1805, taken by the NASA/ESA Hubble Space Telescope. This tight grouping of thousands of stars is located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. The stars orbit closely to one another, like bees swarming around a hive. In the dense centre of one of these clusters, stars are 100 to 1000 times closer together than the nearest stars are to our Sun, making planetary systems around them unlikely. The striking difference in star colours is illustrated beautifully in this image, which combines two different types of light: blue stars, shining brightest in near-ultraviolet light, and red stars, illuminated in red and near-infrared. Space telescopes like Hubble can observe in the ultraviolet because they are positioned above Earth’s atmosphere, which absorbs most of this wavelength, making it inaccessible to ground-based facilities. This young globular cluster can be seen from the southern hemisphere, in the Dorado constellation, which is Portugese for dolphinfish. Usually, globular clusters contain stars which are born at the same time; however, NGC 1805 is unusual as it appears to host two different populations of stars with ages millions of years apart. Observing such clusters of stars can help astronomers understand how stars evolve, and what factors determine whether they end their lives as white dwarfs, or explode as supernovae.
Here's my first image of the globular cluster, M3 in Canes Venatici. This cluster consists of roughly 500,000 stars, bound by gravity and orbits our galaxy. These stars are billions of years old, and very close together.

La pequeña nube de magallanes es una galaxia irregular que se encuentra a casi 200 mil años luz de el sistema solar, se encuentra en la constelación del tucan, se cree que anteriormente era una Galaxia espiral barrada que fue distorsionada por la Vía Láctea. Por otra parte se puede apreciar el Cumulo globular 47 Tucanae (la esfera blanca en la parte superior derecha de la galaxia), en realidad son miles de estrellas ligadas gravitacionalmente en un conjunto casi esférico que órbita en torno a nuestra galaxia. Se encuentra a 16.700 años luz del sistema solar y es el segundo cumulo globular mas brillante después de omega centauri.

Omega Centauri, a globular star cluster in the constellation Centaurus is about 15,800 light years away from where I was standing. Being 12 billion years old and having about 10 million stars, there were evidence that a black hole is pulling them together.
Edited Hubble Space Telescope image of the globular cluster Fornax 5 in the Fornax dwarf galaxy.
Original caption: This NASA/ESA Hubble Space Telescope image shows the globular cluster Fornax 5 in the dwarf galaxy Fornax. New observations of this cluster and three others in the galaxy show that they are very similar to those found in our galaxy, the Milky Way. The finding is at odds with leading theories on how these clusters form — in these theories, globular clusters should be nestled among large quantities of old stars — and so the mystery of how these objects came to exist deepens. This cluster’s position within the galaxy is shown in image G.
M13 is a globular cluster in the Hercules Constellation. It is estimated that there are approximately 500,000 stars in this cluster. It is about 25,000 light years away in our galaxy.

M10, is a globular cluster 25,000 light years away. These are the oldest known bodies in the universe dating back over 13 billion years. They are thought to be failed galaxies which formed just after the big bang and there are at least 200 of them in our Milky Way alone. Notice how most of the stars are yellow or red which shows that they are relatively cool old stars. M10 is predicted to “core collapse” within the next 10 thousand million years, which will create an extremely high star density at its center.
This photo was taken with an SBIG astronomical camera through a 12" reflecting telescope and is a single 20 minute exposure.

Comet Leonard is going to be the brightest comet in 2021. Now it's getting brighter and in half of December, it should reach 4th magnitude. On Friday 3rd of December, the comet was passing the globular cluster M3 in Bootes. Recently it was also one of a few days when it should be clear, so I had to use the opportunity. With my friends, we were going to the edge of Czech Paradise. Already the view through the tried uncovered two small, similarly bright, objects. After that, we set up also the bigger telescopes. Specifically, this pic was taken through an 11-inch telescope Celestron with Hyperstar adapter. It's only one single 15-second exposure. I tried to do also a stack, but DSS had problems with that so I have to be happy with this single-shot for now. Nevertheless, it's my best image of a comet yet (second in all) and absolutely best deep-sky image. Hopefully, it will be clear again in the next days to see the comet even brighter. Because on the 12th of December, it will be the last chance to see it from Czechia.

I decided that i had enough lights and they were such good quality that 2x drizzle might make image a bit better with 2 x drizzle. Also updated with proper flats. Also did some PP to remove light pollution gradient.

Same set of lights, recalibrated with no scaling in Maxim. Also, changed up the PI steps a little to keep from burning the birightest stars.
Otherwise, it's pretty much the same.

Three deep sky objects, in only two minutes, from a city suburb with the cheapest canon lens!
Still testing my bargain astro-photography setup.
This is four 30-second frames at ISO400 taken last night with a 50mm f1.8 set at f2.8. I was testing a home-made camera bracket fixed to an ebay-bargain etx70 telescope. Once it was focussed and composed I set the remote to take 30-second frames continuously, then walked away. The first and last frames always had vibration from me walking on the elevated deck but in between there were some steady ones. I combined the four best in photoshop, auto aligned, adjusted with curves and “dodged” the deep sky objects.
Edited Hubble Space Telescope image of the globular cluster Messier 75. Color/processing variant.
Original caption: This sparkling burst of stars is Messier 75. It is a globular cluster: a spherical collection of stars bound together by gravity. Clusters like this orbit around galaxies and typically reside in their outer and less-crowded areas, gathering to form dense communities in the galactic suburbs. Messier 75 lies in the constellation of Sagittarius (The Archer), around 67 000 light-years away from Earth. The majority of the cluster’s stars, about 400 000 intotal, are found in its core; it is one of the most densely populated clusters ever found, with a phenomenal luminosity of some 180 000 times that of the Sun. No wonder it photographs so well! Discovered in 1780 by Pierre Méchain, Messier 75 was also observed by Charles Messier and added to his catalogue later that year. This image of Messier 75 was captured by the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys.

I accidentally used flats from my 300mm telephoto lens, so vignetting is a bit reversed, and dust spots do not cover up correctly. I was going to redo processing with usual Equinox flats, but then i realized that this was taken with my reducer/flattener. So I'm going to need to take some new flats. So I decided to just upload as is, and will update soon.
