V67 Stars and Galaxies – LoRA for Flux, Flux 2 and Krea 2. Cosmic Visions, Celestial Dreams

Try my models: https://civarchive.com/user/angelomaiota/models

Now also available for Z Image Turbo (let me know if it works)

Premise: If you decide to use my model, I will give you 500 Yellow Buzz if your image is chosen for the cover of CIVITAI, even if used in combination with other models.

R+ images will be hidden from the gallery. LoRA model trained with Flux, Flux 2 and Krea 2.

Putting a Like to the V67 models is worth more than giving me Buzz (yellow/green).

Overview

Step into the infinite expanse of the cosmos, where spiral galaxies swirl in silent majesty, nebulae bloom in vibrant color, and planets, moons, comets, and black holes dance through the void. This LoRA captures the essence of deep‑space imagery – from the delicate glow of a reflection nebula to the violent energy of an active galactic nucleus. Now optimized exclusively for Flux, V67 Stars and Galaxies delivers stunning astronomical visuals with unparalleled material rendering, atmospheric depth, and cosmic scale.

Base Model: Flux (Schnell / Dev / Pro)
Primary Trigger: V67 (prefix) – followed by one or more of the 12 category triggers (see below)

Why Flux + Space / Astronomy?

Flux’s superior handling of textures, lighting, and spatial scale makes it the ideal base for astronomical imagery. The combination produces generations with tangible cosmic realism – you can almost feel the cold vacuum and the distant fire of stars.

CapabilityWhy Flux ExcelsNebula & Gas RenderingFlux distinguishes beautifully between emission, reflection, and dark nebulae, capturing wispy filaments and glowing ionized gasMaterial DetailPlanetary surfaces (rocky, icy, metallic), ring systems, and dust lanes are rendered with coherence and precisionAtmospheric LightStar coronae, zodiacal light, and black hole accretion disks benefit from Flux’s natural handling of extreme contrastsScale & DepthFlux understands the vast emptiness of space – from close‑up lunar craters to galaxy clusters billions of light‑years away

Signature Style Elements

1. Galactic Grandeur

Spiral arms, elliptical halos, interacting pairs – galaxies as both majestic islands and chaotic collisions.

2. Nebulous Color

Rich reds of emission nebulae, cool blues of reflection nebulae, and the deep browns of dark dust clouds.

3. Planetary Variety

Gas giants with ring systems, rocky exoplanets, ocean worlds, volcanic hellscapes – all with realistic surface textures.

4. Dynamic Phenomena

Comet tails, supernova remnants, relativistic jets from black holes, and gravitational lensing around galaxy clusters.

5. Human Presence in Space

Space stations, astronauts on spacewalks, and even ancient star charts – connecting our terrestrial perspective to the cosmos.

6. The Void & The Bright

Deep black backgrounds punctuated by brilliant stars, delicate halos, and the eerie glow of Hawking radiation from micro black holes.

Trigger Words & Usage

All triggers use the prefix V67 once, followed by one or more of the following keywords (separated by spaces or commas).
Example: V67 galaxycore, nebulacloud

Sample Media Prompts (Flux‑Optimized)

These three prompts are calibrated specifically for Flux and represent different aspects of the LoRA:

Prompt 1: Galaxy (Deep Field)

text

a majestic spiral galaxy seen face‑on, glowing golden core, sweeping arms with blue star clusters and pink nebulae, dark dust lanes, surrounded by distant faint galaxies, ultra detailed, 8k, V67 galaxycore

Prompt 2: Planet with Rings

Negative Prompt (Flux‑Compatible)

Flux responds well to minimal negative prompting. This concise version works effectively:

text

nsfw, low quality, worst quality, ugly, blurry, overexposed, cartoon, anime, sketch, drawing, illustration, text, watermark, signature, jpeg artifacts

Note: For space scenes you rarely need to exclude modern or sleek elements – space is timeless. However, avoid adding “photorealistic” if you want artistic interpretations.

Limitations (Flux‑Specific Notes)

⚠️ Requires descriptive prompting – specify “spiral arms”, “dust lanes”, “accretion disk” for best results
⚠️ Very bright objects (e.g., the Sun) may overexpose – use lower LoRA weight or add “soft glow”
⚠️ Extremely dense star fields can become noisy – keep starfield weight moderate or combine with galaxycore
⚠️ Flux Schnell users: keep prompts concise; the fast model trades some detail for speed
⚠️ Color palette can be guided – if you want a specific nebula color (e.g., “blue reflection nebula”), mention it explicitly

Prompting Tips for Best Results with Flux

Do This:

text

[subject] in [setting], [specific features], [atmosphere], V67 [triggers]

Example Good Prompt:

text

a spiral galaxy seen from an angle, glowing golden core, two prominent spiral arms with blue star clusters, dark dust lanes crossing, deep space background, ultra detailed, 8k, V67 galaxycore

Keywords That Strengthen the Style:

For Galaxies: spiral arms, dust lanes, central bulge, tidal tail, star cluster
For Nebulae: emission, reflection, dark, pillar, filament, ionized gas
For Planets: rings, banded clouds, storm, crater, terrain, atmosphere
For Black Holes: accretion disk, event horizon, jet, gravitational lensing
For Comets: ion tail, dust tail, nucleus, coma
For General: ultra detailed, 8k, photorealistic, cinematic lighting, deep space

Avoid:

Overloading with too many conflicting triggers (e.g., eventhorizon + starfield may confuse the black hole’s background)
Contradictory instructions (e.g., “bright and cheerful black hole”)
Extremely short prompts (Flux needs context)
Using V67 multiple times – once at the beginning is enough

The Philosophy Behind V67 Stars and Galaxies

Space is not just emptiness – it is a canvas of unimaginable beauty, violence, and mystery. From the delicate birth of stars in nebulae to the cataclysmic death of massive objects in black holes, the cosmos tells a story of constant transformation. This LoRA aims to bring that story to life with every generation.

“The cosmos is within us. We are made of star‑stuff. We are a way for the universe to know itself.” – Carl Sagan

This aesthetic resonates with those who appreciate:

The grandeur of galactic scales
The intricate details of cosmic phenomena
The scientific romance of astronomy
The emotional pull of the infinite void

Troubleshooting Common Issues

IssueSolutionNot enough detail in spiral armsIncrease LoRA weight to 0.75–0.8, add “intricate dust lanes, bright star clusters”Nebulae look too uniformSpecify “wispy filaments, complex structures” and use nebulacloud with higher CFGPlanets lack surface textureAdd “realistic terrain, detailed craters, banded clouds”Black holes look like simple dark circlesInclude “accretion disk, relativistic jet, gravitational lensing”Stars are too few or too dimAdd starfield trigger and “dense star field, bright stars”Comet tails appear stiffUse “curved dust tail, straight ion tail, dynamic”Space station looks toy‑likeSpecify “realistic textures, solar panels, Earth limb background”Colors are too dullAdd color guidance: “vibrant blue star clusters, pink nebulae, warm golden core”

Credits & Notes

The V67 Stars and Galaxies LoRA draws inspiration from the breathtaking images captured by the Hubble Space Telescope, the James Webb Space Telescope, the Chandra X‑ray Observatory, and the tireless work of astrophotographers and scientific visualization artists around the world. From the iconic Pillars of Creation to the first image of a black hole shadow – this LoRA celebrates humanity’s endless curiosity about the cosmos.

This model is a tribute to astronomers, physicists, and dreamers who look up at the night sky and wonder.
