StarWindow combines a stargazing index, dark-sky map, live sky map, Milky Way core timing, sunset glow, cloud-sea hints, sunrise, tides, moon phases and astronomy events to help decide whether tonight is worth heading out.
Stop cross-checking page by page. Start with tonight's stargazing index, find a dark-sky spot, confirm the galactic-core direction, or switch to sunset and cloud-sea planning.
