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.

It was bitterly cold on the night of 2nd January 2025, but what a beautifully crystal clear starry night it was. So the year began with stargazing late into the night (or early morning).

To begin proceedings I spent over 4 hours capturing this image of IC 342, the Hidden Galaxy in the northern constellation of Camelopardilus.

It is a spiral galaxy the far side of the equator of the Milky Way’s pearly disk, which is crowded with thick cosmic gas, dark dust, and glowing stars that all obscure our view, earning it the nickname of the Hidden Galaxy. It is roughly 11 million light years away and about 50,000 light-years across (half the size of our own Milk Way galaxy).

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 99 (M99), also known as the Coma Pinwheel or Virgo Cluster Pinwheel, is an unbarred spiral galaxy in Coma Berenices. The galaxy is a member of the Virgo Cluster. It is about 56 million light years from Earth. Its designation in the New General Catalogue is NGC 4254.

The Coma Pinwheel has a linear diameter of 85,000 light years. It is one of the brighter spiral galaxies in the Virgo Cluster and appears almost face-on.

Even though the Virgo Cluster Pinwheel is almost the same size as the Milky Way it has an estimated mass of 50 billion solar masses, which is only 5 percent of our galaxy’s mass.

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).

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.

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.

With all these recent clear skies it has been time for mee to set up my trusty telescope. This image of the globular cluster M13 was taken with my big, heavy Celestron C-11 scope.

Messier 13, or M13, is a globular cluster in the constellation of Hercules. As a result it is sometimes called the Great Hercules Cluster and is considered the most spectacular globular cluster in the northern skies. About 145 light-years in diameter, M13 is composed of several hundred thousand stars, with estimates varying from around 300,000 to over half a million. Compared to the stars in the neighbourhood of the Sun, the stars of the M13 population are more than a hundred times more densely packed. They are so close together that they sometimes collide and produce new stars.

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.
