DeepFrame vs Chromahora

eepFrame 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, your own processed thumbnails, and how far each got — finished, captured-but-unprocessed, or stacked-with-no-result-yet. • Lays your own processed shots on the chart, on their own icon, at the exact field of view they were taken at — so you can see what you've already covered. • Browse your whole imaging database: a searchable, sortable, groupable list of every object with each night underneath. Tap a picture for the full frame; tap a name to jump to it on the sky. BUILT FOR THE FIELD • Works fully offline — the ~5200-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.

Great light doesn't wait. Chromahora shows the light for your whole day on one timeline, painted in the colors of the sky, so you know when to be in place and when to shoot. THE LIGHT, HOUR BY HOUR - Golden hour and blue hour, morning and evening, clearly marked - Sunrise, sunset and every twilight in between - A "now" marker, so you always know how long you have left - Tap any phase to jump straight to it PLAN AROUND THE WEATHER - Rain, snow and cloudy spells laid over the timeline - The sky at sunrise and sunset, so you'll know whether clouds will light up or blot out the sun - Hourly UV index and visibility, including fog that cuts how far you can see AFTER DARK - Moonrise, moonset and moon phase - Dark-sky windows for astrophotography, and a clear note when the moon is up or the sky never gets fully dark ANY PLACE, ANY DAY - Use where you are, or search any town, park or landmark - Pick any date to scout a shoot weeks ahead - Times stay in the place's own time zone, so planning a trip abroad just works - Handles the edge cases: midnight sun, polar night and all-day golden hour MADE FOR APPLE DEVICES - Built with Liquid Glass - On iPad and in landscape, the day's details sit right beside the timeline - Supports VoiceOver and Dynamic Type Chromahora is made for landscape, portrait and street photographers, filmmakers, and anyone who chases the light.
