The chamber
Northlume Horizon is the public house — a small planetarium on the canal, built for sitting still under a reconstructed night.
Amsterdam
The dome is dark cloth and timber, not spectacle steel. Canal light enters only through a side door, and only when the program is over.
We show slow skies: a single night, a season, a transit. No voiceover that hurries. The chairs face up. That is the whole argument.
Seating before the first winter program. The dome is not yet lit.
A projected moon, empty chairs. The canal is on the other side of the door.
Hour-long reconstructions of particular nights — solstice, eclipse, a named comet.
Plates from Polar, Orion, and Zenith, projected at the scale of sitting underneath them.
A small gallery for prints and instruments between programs.
Programs at 19:00 and 21:00, Thursday–Sunday
Plantage Chamber
Amsterdam
Sixteen seats. Arrive in the dark; we keep the foyer dim.
Letters are read by the house, not a desk in another city.
