Celestia Dreams XL – Astrophotography SDXL v1.0

🌌Celestia Dreams – Astrophotography SDXL v1.0💫

by Astroscape vision

This is my very first public model release – a labor of love for everyone passionate about the wonders of the night sky.
Celestia Dreams – Astrophotography SDXL was trained entirely on high-resolution astrophotography, from crystal-clear Milky Way panoramas to breathtaking deep-sky vistas. Every image used in training was carefully curated to provide crisp details, rich contrast, and an authentic astrophotography feel straight out of a DSLR or astro-camera setup.

Trigger word: CelestiaDreams astrophotography

Upcoming LoRA Expansions

This model is just the beginning – I’m already working on specialized LoRAs that will perfectly complement Celestia Dreams:

1️⃣ Moonlight Majesty – Lunar Photography LoRA
• Trained on detailed moon photography – all phases, crater close-ups, Earthrise views.
• Perfect for lunar close-ups and telephoto scenes.

2️⃣ Aurora Spirits – Northern Lights LoRA
• Realistic & artistic aurora captures in vibrant greens, violets, and pinks.
• Long-exposure effects and landscape+sky combinations.

3️⃣ Cosmic Frontier – NASA Deep Space LoRA
• Hubble, James Webb & more – galaxies, nebulae, exoplanets, Saturn’s rings.
• Ideal for posters, sci-fi covers, and high-end space art.

4️⃣ Nebula Reverie – Emission & Reflection Nebulae LoRA
• Curated M42/Orion, Horsehead, North America, Rosette, Veil, Carina, Lagoon, and more.
• Emphasizes fine gas structures, star color fidelity, and gentle HDR contrast.
