Messier 12 (M12), also known as the Gumball Globular, is a globular star cluster located in the constellation Ophiuchus. The Gumball Globular lies at a distance of 15,700 light years from Earth and has a diameter of 75 light years. It has the designation NGC 6218 in the New General Catalogue.
The high concentration of stars within globular clusters provides such cramped living quarters that it makes them home to exotic binary star systems where two stars are locked in tight orbits around each other. Matter from one is gobbled up by its companion, releasing X-rays formed from very close encounters between stars in crowded regions. It looks pretty but don't stand too close for very long.

Sometimes I find there are nothing like as many stars to see as other times.
Take this picture which includes M40, a pair of bright stars that Charles Messier thought was a double star. It is in Ursa Major (or the Plough, near to Megrez the star that connects the handle to the plough).
The stars form an optical pair, lying along the same line of sight, but not physically connected to each other as they are now known to be at different distances from Earth. One is about 470 light years away and the other is over 1000.
Messier was trying to identify nebulae but at that time it was hard to distinguish between galaxies and nebulae. This one of the few objects that made it into his catalogue that were neither.
What he missed were two spiral galaxies that my C11 picked up near to M40. The larger one just under the word Major is NGC 4290 and the much fainter one below that is PGC 39934.

This stunning image of the Trifid Nebula, listed as number 20 in the catalog of French astronomer Charles Messier (Messier 20), and also known as NGC 6514 in the New General Catalogue (NGC), was produced by myself, Prof. Dr. Rodolfo Langhi, and Demilson Quintão, on the night of July 23, 2025. We used a DSLR camera (Digital Single-Lens Reflex, a type of camera that combines a digital sensor with a mirror system) attached to a Newtonian reflector telescope with a 203 mm (8") aperture. The entire setup was mounted on a large equatorial motorized mount (Sky-Watcher EQ6R-Pro). To capture the image, we acquired 381 individual frames, each with an exposure of 30 seconds, totaling 3.175 hours of integration. The session took place under the skies near Água Clara – MS, Brazil, where the very low light pollution — due to the region’s distance from major urban centers — allowed for an exceptionally starry sky and significantly contributed to the final image’s high quality. The result reveals beautiful details of the nebula, including numerous regions of gas and dust observable from Earth. The light captured in this image traveled for thousands of years before reaching our camera, enabling us to appreciate its most striking features. The name “Trifid,” meaning “three-lobed,” refers to the dark dust pillars in the center of the nebula, which appear to divide it into three distinct parts. The Trifid Nebula is notable for its unique combination of nebula types — emission, reflection, and dark — and stands out as one of the most visually impressive star-forming regions in the sky. It is located about 5,000 light-years away in the constellation Sagittarius, and has an apparent magnitude of +6.3, visible in a dense and rich stellar field in the night sky.

This is M102, also known as the Spindle galaxy, taken with my C11 earlier this week.
You can make out a crisp dust lane dividing M102 into two halves. The dust lane is slightly warped compared to the disk of starlight. This warp indicates that the galaxy might have experienced gravitational tidal disturbances in the distant past. These disturbances were likely caused by an interaction with a nearby galaxy, as M102 is the largest member of a small cluster of galaxies.
Some faint, wispy trails of dust can be seen meandering away from the disk out into the bulge and inner halo of the galaxy. Background galaxies that are millions to billions of light-years farther away than M102 are also seen through its halo.

Messier 98 (M98) is an intermediate spiral galaxy located in the Virgo Cluster, in the constellation Coma Berenices and is approximately 44.4 million light years from Earth. Its designation in the New General Catalogue is NGC 4192. It is estimated to contain about a trillion stars and an abundance of neutral hydrogen gas and interstellar dust.
This is the longest I have spent on any one target, capturing two-minute exposures for about six and a half hours with my Celestron C11.

On the 2nd of January I took a few minutes to capture this colourful open cluster. It is M38, the Starfish Cluster in the constellation of Auriga.
It is about 3500 light years away and 25 light years across. The cluster's brightest stars form a pattern resembling the Greek letter Pi. (If you squint and tilt your head to the right there is a wide strip of stars representing the top of Pi, a bright fine line of stars which would be the 'left leg' of Pi and a fairly indeterminate linear group forming the 'right leg')
The lines can also be interpreted as looking like a starfish (apparently), hence the name for this cluster of stars.

Messier 88
This galaxy's core holds supermassive black hole roughly 100 million times more massive than our Sun.
Located approximately 47 million light-years away, M88 is a spiral galaxy with well-defined and symmetrical arms. Although it is a member of the Virgo cluster of galaxies, it appears in the neighbouring constellation of Coma Berenices.
M88 contains an active galactic nucleus, meaning the central region of the galaxy is more luminous than the rest of the galaxy. It contains around 400 billion stars and is traveling away from our galaxy.
The galaxy is inclined at an angle of about 30 degrees to our line of sight and its inclination makes it appear like a smaller version of the Andromeda Galaxy (M31).

M109, also known as the Vacuum Cleaner Galaxy (NGC 3992), is a barred spiral galaxy in Ursa Major, which lies approximately 83 million light years away, making it the most distant object in the Messier catalogue.
About half of all spiral galaxies are thought to be barred, including our own Milky Way. Barred spiral galaxies have a central bar-shaped structure surrounded by spiral arms. The central bar is a region of enhanced star formation, where new stars are born.
The diameter of M109 Vacuum Cleaner Galaxy (NGC 3992) is about 120,000 to 130,000 light-years, similar in size, to the Milky Way galaxy.
M109 earned its nickname "Vacuum Cleaner Galaxy" due to its appearance resembling a vacuum cleaner. (That's what 'they' say, whoever they are).
I got this image from about 4 hours observation using 2-minute exposures with my Celestron C11 telescope.

Messier 85 (also known as M85 or NGC 4382) is a lenticular galaxy, in the Coma Berenices constellation. It is 60 million light-years away, and has a diameter of about 120,000 light-years.
A lenticular galaxy is a type of galaxy that is between elliptical and spiral galaxies. They are characterized by their lens-like shape, being flat on the edges and bulging in the middle, and they have used up or lost most of their interstellar matter, resulting in very little ongoing star formation.
Above M85 in this picture is NGC 4394, a barred spiral galaxy in the constellation Coma Berenices about 39.5 million light-years from Earth. It is presumed to be a companion to the lenticular galaxy M85.
This image was captured with over two hours worth of data from a series of 2-minute exposures with my Celestron C11 telescope.

IC 4665 is an Open Cluster in the Ophiuchus constellation. IC 4665 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.
The celestial equator is an imaginary great circle on the celestial sphere that is in the same plane as Earth's equator, dividing the sky into northern and southern hemispheres.
I was using this object to set up and calibrate my guide scope for the night's viewing, which worked out nicely. The bright pattern of stars in this cluster also made a nice image for my first target of the night. The stars were so bright I only needed thirty 30-second exposures to capture this cluster and all those faint stars way in the distant background. The cluster is about 1400 light years away.
If you are interested and still reading this, IC stands for the Index Catalogue which is an update to the earlier NGC catalogue. IC 4665 is not a Messier Object and doesn't have a Messier Number.

These two galaxies are called the Eyes Galaxies. NGC 4438 is on the left and NGC 4435 is on the right. They are a pair of galaxies about 52 million light-years away in the constellation Virgo. The pair are members of the string of galaxies known as Markarian's Chain.
I took this image with over two and a half hours worth of 2-minute exposures using my C11 telescope on Saturday night.

NGC-6888 la Crescent Nebula, nella Costellazione del Cigno, a 4700 anni luce di distanza da noi.
La nube risplende per riflessione, a seguito dell’energia ricevuta durante l’esplosione di una stella in supernova. Nel giro di pochi millenni si prevede che l’oggetto svanirà del tutto, disperdendosi nel mezzo interstellare.

6.10. Podyjska dark sky area
that evening I took a lot of risks and even though I threw away a lot of photos because of the clouds I fulfilled another dream Pleiades with clouds in interstellar space the photo is only over an hour of data to be exact 4440 seconds another more than an hour was spoiled by the clouds but still I am satisfied with the universe which is really not as dark place as people think.
I have to thank Martin for advice on how to process it as best and as honestly as possible even though we haven't met physically yet he really moved me a lot.
The night sky with its beauty and mystery has attracted me since ancient times, but when you just lie there, watch the stars above your head and your eyes gradually get used to the darkness you gradually see not only planes but also satellites, meteors and all that noise you are just amazed.
The universe doesn't have to rush anywhere. Seeing the peace even in the hustle and bustle helps a person but at the same time scares him how small he is compared to it.
Unfortunately, we also ruin this view with the light around us and that's why I'm glad I live where there are still relatively dark skies here and there.
