The NGC 4725 Interaction

2026-07-13T18:47:27.300+03:00

A Quiet Cosmic Encounter

Forty million light-years away, gravity has been shaping this scene for hundreds of millions of years. The elegant barred spiral galaxy NGC 4725 dominates the field, while nearby NGC 4747 bears the unmistakable signature of their interaction—a long, delicate tidal tail stretching into intergalactic space. Below them lies NGC 4712, accompanied by countless distant galaxies that quietly populate the background.Every faint structure visible here emerged after 24 hours and 39 minutes of exposure, allowing the subtle outer halo of NGC 4725 and the fragile tidal stream of NGC 4747 to stand out against the darkness of space.

IC 434 & Barnard 33

2026-04-24T08:40:00.002+03:00

A project captured under less-than-ideal weather conditions, resulting in a shorter total integration time than originally intended.

The goal was a deep L-HaRGB composition, but nature had other plans. To compensate for the missing Luminance data, I opted for a synthetic Luminance approach, blending the grayscale version of the RGB master with the H-alpha data. This allowed me to maintain the structural details of the nebula while bringing out the delicate curtains of ionized hydrogen that the Astrodon 5nm filter captures so beautifully.

It’s a testament to the fact that even when the skies aren't perfect, a bit of processing "alchemy" can still reveal the wonders of Orion.

IC 434 is a bright emission nebula in the constellation of Orion, characterized by its striking red glow which is caused by the ionization of hydrogen by the nearby star Sigma Orionis. However, it is most famous for serving as the luminous backdrop to the iconic Horsehead Nebula (Barnard 33).
The "Horsehead" itself is a dense cloud of cold gas and dust, a dark absorption nebula that stands in stark silhouette against the ionized hydrogen of IC 434. Located approximately 1,500 light-years away, this region is part of the much larger Orion Molecular Cloud Complex and remains one of the most photographed and beloved regions of the night sky for amateur and professional astronomers alike. Capturing the delicate "streaks" of gas in the background requires steady skies and sensitive filters, making it a rewarding yet challenging target.

Shadows and Light: The Running Man Nebula

https://app.astrobin.com/u/arasteo?i=rbmduy

While the Great Orion Nebula (M42) often steals the spotlight, its neighbor, NGC 1977, offers a breathtaking display of cosmic contrast. This image is the result of a 12-hour deep dive into the "Running Man."

We pushed for a darker processing style to highlight the "ghostly" appearance of the dust clouds against the deep space background. The massive amount of Luminance frames helped bring out the fine, hair-like details in the reflection nebula's core. By carefully managing the star field, the focus remains on the dynamic interaction of light and shadow that gives this nebula its famous name.

IC 410: The Cosmic Tadpoles in the Heart of Auriga IC410 FINAL.png

2025-12-24T13:02:00.001+02:00

Deep within the constellation of Auriga, approximately 12,000 light-years from Earth, a drama of birth and survival has been unfolding for millions of years. The nebula IC 410 is more than just a cloud of gas and dust; it is a celestial nursery where light and matter collide to shape the unknown.

Life Within the Shadows
What makes IC 410 truly unique, earning it the nickname "The Tadpoles," are the two distinct structures of dense gas and dust that appear to swim toward the nebula's center. These "tadpoles," each spanning about 10 light-years, are the resilient survivors of a relentless cosmic onslaught.
Just as tadpoles in Earth's ponds prepare for their transformation, these cosmic structures gestate the future. Within their dark cores, gravity triumphs over pressure, forging new stars that will one day illuminate our galaxy.

The Breath of Stars
The engine behind this spectacle is the open star cluster NGC 1893, nestled at the nebula's core. These young, scorching, and massive stars emit intense ultraviolet radiation and powerful stellar winds that "sculpt" their surroundings.

It is these very winds that have molded the "Tadpoles" into their iconic shapes, stripping away lighter gas and leaving behind dense heads and long tails. These tails point away from the cluster's center, as if the tadpoles are swimming against the tide of stellar radiation.

The End of a Star's Life M27 Nebula - A Cosmic Dumbbell

The M27 nebula, also known as the Dumbbell Nebula, represents one of the most spectacular and brightest planetary nebulae in the night sky.

The characteristic dumbbell shape that gives the nebula its name results from its unique structure.
It is located approximately 1,360 light-years from Earth in the constellation Vulpecula

Hidden at the center of the nebula lies a white dwarf star with a temperature of approximately 85,000 K. This extremely hot star is the remnant of a star that exhausted its nuclear fuel and expelled its outer layers, creating the dazzling spectacle we see today.

The nebula glows with a distinctive green-blue color, which is primarily due to doubly ionized oxygen.
This color, combined with the red regions created by ionized hydrogen, gives the nebula its impressive appearance. Scientists estimate that the M27 nebula formed approximately 9,800-10,000 years ago, based on measurements of its expansion velocity.

The M27 nebula remains one of the most accessible and spectacular targets for amateur astronomers, offering a window into the future of our own Sun, which in about five billion years will follow a similar evolution.

The Trifid Nebula

2025-08-04T15:28:00.004+03:00

Starless view

Original view

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum–Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

NGC 4565 Needle Galaxy

2025-07-30T19:15:00.001+03:00

NGC 4565, also known as the Needle Galaxy, was discovered by the astronomer Sir William Herschel on April 6, 1785. Herschel, who also discovered the planet Uranus, first identified this prominent edge-on spiral galaxy in the constellation Coma Berenices. Its bright, narrow appearance earned it the nickname "Needle Galaxy." The galaxy lies approximately 30 to 40 million light-years away from Earth and is a well-studied example of an edge-on spiral galaxy.

Full Moon in ir 850nm

2025-04-17T19:37:00.003+03:00

An interesting view of the full moon at 850 nm with the ZWO IR 850 filter.

this filter allows the passage of infrared light at 850 nm, which can be useful for cameras sensitive to the infrared spectrum. This helps isolate specific details and features in planetary and lunar objects that are more visible in infrared light.

By using the IR 850nm filter, interference from visible light is reduced, which can improve the contrast and sharpness of images, especially under conditions of atmospheric turbulence or in the presence of ambient lighting.

If you are using a color camera such, you can use it as a monochrome camera with this filter by setting the white balance parameters (WB_R and WB_B) to 50, so that no white balance is applied and you can fully exploit the sensitivity in the infrared spectrum.

Στον μικρό αλλά πλούσιο σε όμορφους γαλαξίες αστερισμό των Θηρευτικών Κυνών βρίσκεται ο Γαλαξίας NGC 5033. Οι εκτιμήσεις απόστασης ποικίλλουν από 38 έως 60 εκατομμύρια έτη φωτός από τον Γαλαξία μας. Ο NGC 5033 έχει έναν πολύ φωτεινό πυρήνα και έναν σχετικά αχνό δίσκο.

NGC 5033 is an inclined spiral galaxy located in the constellation Canes Venatici. Distance estimates vary from between 38 and 60 million light years from the Milky Way. The galaxy has a very bright nucleus and a relatively faint disk. Significant warping is visible in the southern half of the disk. The galaxy's relatively large angular size and relatively high surface brightness make it an object that can be viewed and imaged by amateur astronomers. The galaxy's location relatively near Earth and its active galactic nucleus make it a commonly studied object for professional astronomers.

NGC 1333

Πρώτο φως από το NGC1333.
Λόγω των άσχημων καιρικών συνθηκών που επικρατούν τους τελευταίους μήνες κατάφερα να συλλέξω μόνο 7 ώρες αν και η αρχική μου πρόθεση ήταν για τουλάχιστον 12 με 14 ώρες.Ελπίζω του χρόνου να καταφέρω να το ολοκληρώσω.
Το NGC1333 είναι ένα νεφέλωμα αντανάκλασης ,βρίσκεται στον αστερισμό του Περσέα και απέχει περίπου 960 έτη φωτός.
Οι φωτεινές περιοχές του νεφελώματος αποτελούνται από πίδακες καυτής σκόνης και λαμπρών αερίων που φωτίζονται από πρόσφατα σχηματισμένα άστρα.
Στην πραγματικότητα το NGC1333 περιέχει εκατοντάδες άστρα ηλικίας μικρότερης του 1 εκατομμυρίου ετών, που τα περισσότερα είναι κρυμμένα από τα οπτικά μας τηλεσκόπια λόγω της υπέρπυκνης σκόνης.
Αυτό το χαοτικό περιβάλλον ίσως είναι παρόμοιο με αυτό που δημιουργήθηκε ο δικός μας ήλιος πριν από 4,5 δισεκατομμύρια χρόνια!!!

Το Νεφέλωμα της Τουλίπας(Sharpless 101) είναι νεφέλωμα εκπομπής στον αστερισμό του Κύκνου. Απέχει περίπου 6,000 έτη φωτός από τη Γη και η διάμετρός του υπολογίζεται στα 70 έτη φωτός.

Στο δεξί κάτω άκρο της φωτογραφίας ακριβώς κάτω από το αχνό τόξο που σχηματίζεται, έχει καταγραφεί η περιοχή που βρίσκεται η πρώτη υποψήφια Μαύρη Τρύπα Cygnus X-1 και μια από τις ισχυρότερες πηγές ακτίνων Χ του γαλαξία μας.

The Tulip Nebula (Sharpless 101) is an emission nebula located in Cygnus constellation. It lies at an approximate distance of 6,000 light years from Earth. It occupies an area of 16 x 9 arc minutes of apparent sky and has a linear diameter of about 70 light years

The Tulip Nebula is located in the same region of the sky as the microquasar Cygnus X-1, the first galactic X-ray source widely believed to be a black hole. Cygnus X-1 consists of a star, HD 226868, and a very small high-mass object. The two orbit around each other with a period of 5.6 days. The object was one of the first ever candidates for a black hole.

A new project begins...I hope to finish next year the other 2 narrowband filters
