A scheduling puzzle about running an observatory for twelve fixed nights. Pick a target (nebulae, star clusters, galaxies, pulsars and more), then click a time slot to set its exposure start. Each exposure must fit fully inside its visibility window under the moonlight limit, and switching between the blue spectrograph, red spectrograph and wide-field camera needs a calibration gap. Pack the night into the official minimum span with zero risk for three stars. An abstract puzzle, not a real observing plan.
