A calendar of moon phases, true-dark windows, weather, planet positions, and the night's best deep-sky targets — tuned to Zion's latitude. Updates each night with cloud cover, transparency, and seeing pulled from 7 km weather models, plus precise moonrise/set and astronomical-twilight windows.

The constellations, the planets, and the deep-sky wonders — a single hub for everything you can point a scope, binoculars, or your eye at tonight. All 88 official constellations, the 8 planets with live tonight-positions, and the complete Messier catalog of 110 deep-sky objects with rise/set times.

Interactive maps of the darkest stargazing spots across Utah's Big 5 — Zion, Bryce, Capitol Reef, Canyonlands, Arches — plus Cedar Breaks and the St. George region. Bortle-rated overlooks, trailheads, and remote sites with GPS-aware "you are here" markers and detailed info for each location.

The year's meteor showers and headline celestial events — oppositions, eclipses, conjunctions, and perihelion passages — each counted down to the night. Built on NASA/JPL ephemerides; tells you exact peak times and moon-interference at your latitude.

Aim your phone's camera at any peak or patch of sky and read the exact compass direction and altitude — for planning where the Milky Way or moon will rise. Live AR overlay aligned with the phone's magnetometer and accelerometer, calibrated for true (not magnetic) north.

A labelled atlas of the seas, craters, and peaks of the moon, with the moving terminator showing where shadows fall sharpest tonight. Includes the libration model and the precise visible phase calculated from real-time Sun-Moon-Earth geometry — accurate to seconds of rotation.
