Store description excerpt
AstroTool — Astrophotography Planner & Sky Map Plan better. Shoot more. Miss nothing. AstroTool is the complete astrophotography companion for iPhone — from scouting tonight's targets to logging every capture. A live sky map you can actually use in the field, planning tools built around how astrophotographers think, and a session logger that keeps your imaging history in one place. FREE FEATURES Sky Map A fully rendered live sky chart with 100+ bright stars, all 110 Messier objects, the Sun, Moon, and all planets. Constellation lines, constellation name labels, the Milky Way band, and the ecliptic arc are all drawn in real time. Tap any object for instant identification — name, type, magnitude, and position. Procedural rolling-hill horizon with compass ticks and cardinal labels. Motion-driven so the sky moves as you move. Deep Sky Catalog Browse the complete Messier catalog with search, type filters, and sort by ID, magnitude, or altitude. Every object shows rise, transit, and set times for your location, a visibility chart for tonight, and your full capture history for that target. Mark favorites and pick up right where you left off. PREMIUM — ONE-TIME UNLOCK Planner Everything you need before you head out. Moon phase and illumination with an imaging impact rating. Full twilight schedule — civil, nautical, and astronomical dusk and dawn with total dark-sky hours. All visible planets with live altitude and transit times. Jupiter's Galilean moons in a live canvas diagram. Best targets tonight ranked by a composite altitude and moon-separation score. Target schedule to plan your imaging windows object by object.

Session Logger Log every observing session with sky conditions — Bortle scale, seeing, and transparency.

Export any session as formatted text to share or archive. Full equipment manager for telescopes and cameras with sensor specs, focal length, and reducer support.
