Scout a composition by day: scrub the sun and moon from dawn to dusk over the live camera, see where shadows fall, and check the cloud forecast hour by hour.

The longest exposure before stars trail, tuned to your camera, lens, and the part of the sky you’re shooting.

A field notebook for every shoot — target, gear, settings, conditions, and results. Saved on your device.

How many subs to shoot tonight, total integration time, and how stacking sharpens faint detail.

Upload any night-sky photo to see which stars, constellations and deep-sky objects are in the shot, and exactly where the camera was pointing.

When your target peaks highest — the best time to shoot — and when a German mount needs its flip.
