Clear night ahead? +Frames tells you what to shoot - and how to shoot it. THE ATLAS The whole sky in your pocket: ~12 million stars down to magnitude 14, 8,800 deep-sky objects, Sun, Moon and planets, asteroids, comets and 16,000 satellites moving live. Real astrophotos lie on the map, galaxies are drawn with their true orientation, and every object opens a card with the numbers that matter tonight. TONIGHT'S TARGETS, RANKED The Night tab scores every object for YOUR equipment, YOUR sky and YOUR horizon: altitude, moon distance, usable dark window, field-of-view fit. Grade A to E - the best target for tonight is always on top. FRAME IT True field-of-view preview for your camera or eyepiece. Rotate the frame, plan mosaics up to 4×4, check the sampling. An 8-sector horizon profile per site keeps trees and rooftops out of your plans. PROJECTS Track every target over nights: subs, exposure, gain, filter by filter. Camera angle and position are saved with the project and restored when you return. Export the plan in ASIAIR format. ASTRO BUDDY Your AI assistant knows your gear, your site and tonight's sky. Ask what to shoot, why a filter fits, how long to expose — computed from your sensor, your Bortle sky and the Moon. Type "I have a ZWO ASI2600MC" and he looks it up and saves it to your gear. AND MORE - Plate solving puts your own photos on the atlas - AR mode shows where a target sits in your real sky - Red night mode protects your dark adaptation - Calendar with moon phases and events, searchable up to 2050 - Works offline; no account, your data stays on your device (private iCloud backup) +Frames Premium unlocks the whole app - 7-day free trial.
