HOHLRAUM
Hohlraum Observatorium · Kessler Ridge

Light is cut
from the dark.

A scheduling console for the observatory where nothing floats. Every dome slot, instrument, and observing run hangs in balance on a single diagonal axis — colour is light let through a window, never paint on a tile.

The method

Three ideas, hung in balance

Not a poster you read top to bottom — a mobile you read by weight. Each principle counterweights the next around one pivot.

Subtractive

Cut, not stacked

The dark ground is the figure. Colour appears only where a window is punched through — apertures, never floating tiles.

Balanced

One diagonal axis

Layout cantilevers off a single beam. Add a heavier number and the whole queue re-levels around the pivot point.

Plotted

Read across

Type sets in mixed-case stacked baselines like a star chart — measured and plotted, not an uppercase shout.

On the ridge

Instruments, mounted on the beam

  • Wide-field surveyFourteen domes plotted to one master schedule, each slewing on its own moment-arm.
  • Narrowband stackHα and OIII windows cut into the night; calibration frames matched to instrument temperature.
  • Red-light consoleA dark-adapted operating surface — luminous primaries on a midnight ground, nothing glares.

Hang tonight's runs on the beam.
