The Triangulum Galaxy (M33) is one of our closest galactic neighbours, sitting about 3 million light-years away and stretching roughly 60,000 light-years across. It’s a beautiful face-on spiral, rich in star-forming regions, which makes it a perfect target for H-alpha.

8 hours of RGB captured its soft stellar glow, with an extra 1.6 hours of H-alpha revealing the bright nebulae scattered through its spiral arms. The light in this image began its journey long before humanity ever looked up.

🌌 M108 (NGC 3556) is a spiral galaxy in Ursa Major, 45 million light-years away from earth🌎

Notable for its disturbed structure, thick dust lanes, and asymmetric disk, likely the result of past gravitational interactions.

I posted this picture a couple of days ago, but did a better job on the process here😇

NGC2841

a massive unbarred spiral galaxy in Ursa Major, located 46 million lightyears away. It is classified as an anemic spiral, showing relatively low star formation despite its well defined structure. The galaxy has a large, luminous bulge, tightly wound spiral arms, and prominent dust lanes visible across the inner disk.
NGC 2841 hosts a low-luminosity AGN and a supermassive black hole estimated at ~300 million solar masses, significantly larger than Sagittarius A* in the Milky Way.

🌌 A Cosmic Gathering in Canes Venatici

Meet Messier 106, a majestic spiral galaxy, about 23–25 million light-years away. She’s one of our brighter and closer galactic neighbors, boasting a supermassive black hole at her core that powers mysterious “anomalous arms” visible in X-rays and radio waves.

Right beside her dance some faithful companions: the elegant edge-on spiral NGC 4217 (a possible true neighbor), the smaller irregular NGC 4248, and the tiny interacting pair NGC 4231 & 4232.

Together they form a quiet little galaxy group, hanging out in the vast emptiness of space.
Captured from my backyard with 289 sub-exposures of 180 seconds each, that’s 14.45 hours of total integration time!

Every photon tells a story from millions of years ago.
What a privilege to peek into this distant backyard star/galaxy party! ✨

I captured IC 1805 (Heart Nebula) with 3.5 hours of total integration time. Over multiple exposures, the signal built up enough to clearly show the structure of this emission nebula.

My gear:
• 📷 ZWO 533MC Pro
• 🧭 Sky-Watcher EQ6-R Pro
• 🔭 TS-Optics f/3.9 Newtonian
• 🎯 220mm Mini Guide Cam
• 🔩 Askar M45 OAG
• 🎨 Optolong L-eXtreme filter

The colors in the image come from specific ionized gases:
Red / yellow = Hydrogen (H-alpha)
Green/blue-green = Doubly ionized oxygen (OIII)
Some blue tones also come from oxygen emission or scattered starlight.

Each color represents a real emission line captured through the L-eXtreme narrowband filter and combined during processing — essentially a chemical map of the nebula. taken in De Heen, Noord-Brabant, Netherlands by @myastroselection

Through my f/3.2 Newtonian, NGC 891 slipped quietly into view — a silver needle of light floating edge-on in the dark. 🌌
Captured with the 533MC Pro and an Optolong UV/IR cut, every photon felt earned, every dust lane a whisper from another time. 🔭✨

NGC 891 lies about 30 million light-years away in Andromeda, a near twin of our Milky Way seen perfectly edge-on. 🌠
One light-year equals about 9.46 trillion kilometres, so this galaxy sits nearly 30 million times that distance away — an almost unimaginable stretch of space for that light to cross. ✨🚀
Its thick, dark dust lane slices through the core, while faint hydrogen clouds and stars stretch far above the galactic plane. 🌀
Surrounded by distant background galaxies, it floats in a quiet patch of sky, a reminder of how vast and layered the universe really is. 💫

Just 3 hours of integration, yet this galaxy still told its story, calm, distant, infinite. ✨ taken in De Heen, Noord-Brabant, Netherlands by @myastroselection

NGC7331 and Stephan’s Quintet

Can you take “good” photos without a lot of data and calibration frames?

The answer is yes, you can. @cvz_astro and I tried how much detail we could extract from this data that I actually wanted to remove.

I stacked it, and Kees edited it. The photo contains 39 subs of 180 seconds—NO flats, NO darks, NO biases, only lights and horrible backfocus..

What I learned from Kees is that with careful editing in Pixinsight you can achieve a lot, little by little, without going overboard.

Technical data.

The most freaking amazing picture i’ve ever made.

The Elephant Trunk Nebula is a towering pillar of gas and dust in the constellation Cepheus, about 2,400 light-years from Earth. Its shape, stretching like a great animal’s trunk, is sculpted by the intense radiation from nearby young stars. Inside, new suns are being born, hidden behind thick clouds that glow under the starlight. Over millions of years, the same forces that created the trunk will also tear it apart — a cosmic reminder that even the most beautiful shapes in space are only temporary.

De Olifantsslurfnevel is een torenhoge pilaar van gas en stof in het sterrenbeeld Cepheus, ongeveer 2.400 lichtjaar van de aarde. Zijn vorm, die zich uitstrekt als de slurf van een grote olifant, is gevormd door de intense straling van jonge sterren in de buurt. Binnenin worden nieuwe zonnen geboren, verborgen achter dikke wolken die oplichten in het sterrenlicht. Over miljoenen jaren zullen dezelfde krachten die de slurf hebben gevormd hem ook vernietigen — een kosmische herinnering dat zelfs de mooiste vormen in de ruimte slechts tijdelijk zijn.

In the constellation Cygnus, 5,000 light-years away, a star named WR 136 burns with ferocious intensity. This Wolf-Rayet star, a massive beast in its twilight years, is the heart of NGC 6888, the Crescent Nebula. Once a colossal supergiant, WR 136 has shed its outer layers in a tempest of stellar wind, hurling gas outward at millions of miles per hour. These winds collide with earlier, slower-moving ejections, sculpting a glowing shell of ionized gas that spans 25 light-years—a cosmic bubble painted in hues of crimson and teal, visible only through the keen eyes of telescopes and filters. The Crescent Nebula, as it’s called, is a testament to the star’s violent transformation, a prelude to its inevitable supernova finale.
