The prompt

Prompt

A large steampunk brass telescope mounted on a clockwork equatorial mount inside a domed observatory, the telescope with a riveted brass tube and a glass lens cap, the mount driven by exposed bronze gears and a winding crank, a brass control panel with analog dials and gauges, the observatory dome open to a starry night sky, star charts pinned to a curved wooden desk nearby, a small gas lamp on the desk casting warm light, no text, no letters, no numerals on the dials

How to use this prompt

  1. 1

    Open the generator that matches the model and version above, and start a new image rather than editing an existing one.

  2. 2

    Set the output to 3:2. That is the only output setting recorded for this entry, and it is what produced the 768 × 516 image on this page.

  3. 3

    Paste the prompt exactly as written. Changing the wording changes the image, so copy it before you edit.

  4. 4

    Generate, then change one thing at a time. The result will not be pixel-identical to the image on this page, because no seed is recorded for it.

Only an aspect ratio is recorded for this entry. GPT Image and DALL·E do not expose a sampler, step count, or CFG value in the interface this was tested in, so there are no numbers to match — the prompt text and the aspect ratio are the whole instruction. Resize by describing the framing in words rather than reaching for a parameter.
