Fictional Nebula in Telescope Style

Write a prompt for a fictional nebula that looks like a processed telescope image, not a sci-fi poster with a planet and a slogan. IMAGE Structure: [PILLARS | A RING | A THIN VEIL] Palette: the narrowband mapping I name [SHO HUBBLE PALETTE OR NATURAL COLOR] Stars: many, sharp, different sizes, a few with diffraction spikes if I want a space-telescope feel. No planet in the foreground, no spaceship, no text, no border. Framing: the brightest region off-center. PROMPT Dust lanes that obscure stars behind them. A sense of transparency where gas is thin. Noise subtle, not a cartoon gradient. Negative: lens flare from a sun that is not in frame, giant moon, watermark, letters. --ar 1:1 and a 16:9 crop description.
