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 a broadened deep-sky catalog spanning Messier, Caldwell, NGC, and IC 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 kit of calculators and planners for shooting the night sky — the NPF rule for the longest trail-free exposure, an imaging session log, an integration & stacking planner, and meridian-transit times for 50 popular deep-sky targets. Everything runs on your device and works offline.
