An astronomical instrument similar to a heliostat that reflects celestial light into a fixed direction, allowing continuous observation of the sky.
From 'coelo-' (sky/celestial from Greek 'koilos') + '-stat' (something that stands still), following astronomical instrument naming conventions.
A coelostat is like a mirror on a motorized mount that tracks the sky—astronomers use it to keep a steady view of stars and planets without telescope rotation!
