Desert observatory studies a glass comet # Desert observatory studies a glass comet - [Model Chroma1-Flash](/models/chroma1-flash) - Landscape 3:2 - 1536 × 1024 · XL - 12 steps - Max quality - iPadMac ## Prompt and Settings Copy prompt A remote observatory crew in pressure suits watches a transparent comet core suspended above a basalt platform. The action unfolds beside modular research tents, antenna dishes, cable reels, and wind-carved dunes under a pale sky. Wide 3:2 composition, camera at waist height, 24mm lens, crew placed along the lower third for scale. Low sun skims across dust and black stone. Chroma1-Flash style, concept art clarity, hard surface design, precise silhouettes, restrained sci-fi palette. ### Negative Prompt Copy negative prompt logos, readable text, blurry crew, malformed suits, extra fingers, watermark, overexposure, tangled geometry Seed 669121369 Steps 12 Quality Max Size 1536 × 1024 Made With Private Diffusion on a Mac with Apple Silicon Share Make it on your own Mac with 24 GB or more. Nothing you type leaves the device. [![Pre-order on the App Store](/app-store/pre-order-badge/en/pre-order.svg)![Pre-order on the App Store](/app-store/pre-order-badge/en/pre-order-dark.svg)](https://testflight.apple.com/join/DQwfQsEg) ## Why This Prompt Works This concept image uses an unusual scientific encounter as the hook, making the comet core the main shape in the frame. The phrase about the core suspended above a basalt platform carries both composition and scale, while the crew along the lower third gives Chroma1-Flash practical silhouettes to define. Low sunlight across dust and stone supports a polished design sheet feel with enough environment detail to suggest a larger story. ## Recreate It in Private Diffusion 1. Paste the prompt into Studio and choose Chroma1-Flash. 2. Set Size to XL and Aspect Ratio to Landscape 3:2. 3. Type 669121369 into Seed. On a Mac, switch off Randomize first. 4. Paste the negative prompt into Negative prompt. 5. Switch on Max quality (slower). Those are the settings that made this picture, and they run on your own Mac with 24 GB or more, with nothing uploaded. ## Filed Under - [Concept Art](/prompts/concept-art) - [Sci-Fi](/prompts/sci-fi) -
