Wer beabsichtigt, meine nach dem Urheberrechtsgesetz (UrhG) geschützten Werke, also meine Fotos (UrhG § 2 Absatz 1 Satz 1 Nr. 5), zu verwenden ohne meine ausdrückliche Einräumung von Nutzungsrechten (UrhG § 31),

den weise ich schon mal auf die Folgen hin, zunächst auf UrhG § 106 Unerlaubte Verwertung urheberrechtlich geschützter Werke:

"(1) Wer in anderen als den gesetzlich zugelassenen Fällen o

hne Einwilligung des Berechtigten ein Werk oder eine Bearbeitung oder Umgestaltung eines Werkes vervielfältigt, verbreitet oder öffentlich wiedergibt, wird mit Freiheitsstrafe bis zu drei Jahren oder mit Geldstrafe bestraft. Neben UrhG § 109 Strafantrag bleibt mir als rechtmäßigem Urheber meiner Fotografien noch UrhG § 97 Anspruch auf Unterlassung und Schadensersatz, was bei privater Nutzung je Foto und angefangene Woche der Benutzung im Internet mindestens 40,- Euro ausmacht (vgl. Brandenburgisches Oberlandesgericht, Urteil vom 03.02.2009 - Aktenzeichen: 6 U 58/08) plus Anwaltskosten laut UrhG § 97a Abmahnung. Sollte es aber (gleich oder danach) zu einer Klage kommen, kommen noch die Gerichts-Verfahrens-Kosten hinzu – und Sie bezahlen dann zusätzlich noch meinen und Ihren Anwalt. Angesichts dieser Kosten sollte es erheblich preiswerter sein, vor einer Verwendung meiner Werke im Internet (oder sonstwo) ein Nutzungsrecht mit mir zu vereinbaren – extrem preiswert für private oder gemeinnützige Zwecke (beides optional!) oder ansonsten gegen ein branchenübliches Honorar.

M42 – The Orion Nebula ✨

The Orion Nebula (M42) is one of the most famous and active star-forming regions in the night sky.
Located just below Orion’s Belt, this vast stellar nursery glows with ionized gas and dust,
illuminated by the intense radiation of newly formed, massive stars at its core.

Within this region, intricate structures of hydrogen and subtle color transitions reveal
the dynamic processes shaping stars and planetary systems in their earliest stages.

NGC 7380 – The Wizard Nebula ✨

NGC 7380, also known as the Wizard Nebula, is an emission nebula with an embedded open star cluster
located in the constellation Cepheus. Its dramatic shapes of glowing hydrogen and dark dust lanes
create the unmistakable appearance of a celestial wizard emerging from the cosmic clouds.

Intense H-alpha regions, subtle oxygen structures, and a rich star field combine to reveal
the complexity and depth of this fascinating star-forming region.

NGC 884 – The Double Cluster ✨

NGC 884, also known as Chi Persei, is one half of the famous Double Cluster in the constellation Perseus.
Together with its twin NGC 869, it forms one of the most spectacular open cluster pairs in the northern sky.

Rich fields of young, hot blue stars are embedded in a dense Milky Way background,
revealing the impressive scale and depth of our galaxy in this region.

Caldwell 25 – The Intergalactic Wanderer ✨

Caldwell 25 (NGC 2419) is one of the most remote globular clusters associated with the Milky Way,
often referred to as the Intergalactic Wanderer due to its vast distance and unusual orbit in the galactic halo.

Suspended far beyond the main stellar disk, this ancient cluster challenges our understanding of
galactic formation and evolution, appearing almost like a relic from another era of the universe.

M31 – The Andromeda Galaxy ✨

Our nearest large galactic neighbor and the most distant object visible to the naked eye.
The Andromeda Galaxy (M31) dominates the Local Group and is on a slow collision course with the Milky Way,
offering a breathtaking view of spiral structure, dust lanes, and vast stellar populations.

Surrounding M31, faint background galaxies and subtle details emerge in the field of view,
a reminder of the immense depth and scale captured in this image.

I am using a Lacerta 341/72 apochromatic refractor (f/4.7) as my main imaging telescope 🌌 (mobile).
The system is equipped with a cooled ZWO ASI294MC Pro astrophotography camera for low-noise deep-sky imaging ❄️📷.

Guiding is handled via an off-axis guider (ZWO OAG) paired with a ZWO ASI120MM Mini guide camera, ensuring precise tracking and minimal differential flexure 🎯.

The entire setup is controlled by a ZWO ASIAIR PLUS, providing integrated camera control, guiding, plate solving, and automation 🛰️🧠.

The mount is a ProxySky UMI 17 R, offering stable tracking and sufficient payload capacity for long-exposure astrophotography ⚙️🌠.

🌙 The Moon in Detail

Captured with my modified Newton telescope using a luminance filter.
The final image was created from a video sequence, with the individual frames stacked to extract as much fine detail from the lunar surface as possible.

The luminance filter provides high sharpness and clean contrast, making subtle structures and transitions on the Moon clearly visible.
