DeepFrame

Tonight's sky for your gear and your horizon: every catalogue object's path, the exact window it's high enough to image well, and what you've already shot — all offline.

DeepFrame is a deep-sky imaging planner for astrophotographers. Point it at your location and any night — tonight or a simulated one — and it shows exactly what's worth shooting and when.

WHAT IT DOES • Plots every catalogue object's path across your sky from dusk to dawn, with a midnight marker. • Picks out the imageable window — where each object is high enough (alt ≥ 25°) and culminating near midnight — so you know the best hours to capture it. • Draws your rig's true field of view around any object, so you can judge framing before you set up. • Overlays a real all-sky survey photo, the Milky Way, constellations, named stars, the ecliptic, planets and the Moon — toggle each layer to taste. • Masks YOUR local horizon: capture a 360° skyline with the camera (a guided sweep, or import a panorama), edit the sky away, and objects that never clear your trees and buildings are flagged as blocked. • Keeps your imaging log: per-object sessions with date, scope, camera, filters and exposure, and your own processed thumbnails.

BUILT FOR THE FIELD • Works fully offline — the ~1500-object catalogue, all maths and your data live on device. • Fast, gesture-driven all-sky chart: pan, pinch to zoom, tap any object for its card, tracks and imaging log. • A time capsule to preview any past or future night.

EVERYTHING IS FREE The full catalogue, every object type, magnitude and size, unlimited rigs, locations and your own shots — all free. No account, no ads, no tracking.

Built with open astronomy data (OpenNGC, VizieR/CDS) and public survey imagery (Pan-STARRS via CDS; NOIRLab all-sky photo). Full credits in the About screen.
