4.0 is the biggest Astrian Light update yet. - All your gear: over 600 lenses and 230 cameras in the catalog, and if yours isn't there, type it in and the numbers still work. - Terrain counts at night too: dark-sky hours and the Milky Way are measured against your real horizon, not a flat one. - A new home screen: all ten tools as tiles, each with today's figure. - Buttons your way: in Settings, "Buttons" switches between symbol plus name, or name only. - Clearer plans: every plan says when and where, and the "…" button holds the rest. - Milky Way: when the Moon is up all night, it takes you to the next moonless night. - Better on iPad, with two columns, and more accessible: large text, VoiceOver and contrast. - Times follow your iPhone's format, constellations use their official names, and sky search works in English, Spanish or Portuguese. - More stable: fixed a crash at launch and several wrong times and figures, including eclipse times.

Astrian Light 2.0.3 This version turns Astrian Light into a planner that knows the place where you’re going to shoot. REAL TERRAIN, IN EVERY CALCULATION Your horizon is now part of the plan. Astrian takes the terrain into account when calculating Golden Hour, Milky Way visibility, and the conditions for each night. If a mountain will block the sunrise, you’ll know until what time. PLAN DIRECTLY ON THE MAP Mark where you’ll set up your camera and where you’ll point it. Check distance, azimuth, and elevation difference, calculate the shadow an object will cast, and preview the framing you’ll get with your camera and focal length. Then save the plan with the location, date, and gear you’re taking. TEN CALCULATORS, USING YOUR GEAR Add your cameras and lenses and Astrian uses them directly in its calculations. Calculate depth of field, hyperfocal distance using your lens’s actual aperture stops, exposure for pinpoint stars, field of view, filters, timelapse, and more. If you use an adapter, Astrian automatically applies the effective focal length. STAR TRAILS, OVER YOUR HORIZON See the arcs the stars will trace directly over the horizon and framing you’ve planned. Not over a generic rectangle: over the photograph you’re preparing. COMPARE LOCATIONS AND NIGHTS Choosing between two places? Compare up to three locations at once and check the upcoming nights and sky conditions for each before deciding where to go. WIDGETS Bring your next shot to your Home Screen. See the countdown to an eclipse, the Moon, or Golden Hour for the location you’ve chosen, without opening Astrian. YOUR SKY Check how dark the sky is at your location and find out whether the conditions are worth the trip before you leave home. AND MORE Your plans and gear sync with iCloud, so they’re available across all your devices. Get alerts for new moons, moonless nights, and supermoons. And if something isn’t working or there’s a feature you’d like to see, you can now tell us directly from Settings. Your message is read by a real person.

This version is a complete redesign: New eclipse view: full-screen map with the shadow sweeping across the terrain, contact times, and whether your local horizon will hide the Sun. Redesigned golden hour, with the full day's light and your real horizon on the map. "My gear": save your cameras and lenses to feed the calculators and trip planning. A fresh, consistent design across the whole app, built for iPad too. More precise and stable sky compass. Many performance and polish improvements. Eclipses are always free.

What’s New in Astrian Light 1.6 Augmented Reality has arrived in Astrian Light. * Eclipse AR: preview where the eclipse will appear from your location and check whether mountains or terrain could block your view. * Golden Hour AR: see where the Sun will move across your landscape during Golden Hour and plan your composition. * Today’s Sky in AR: locate the Sun and Moon in the sky from your current position. * Simulated Moon phase: see the Moon’s position and appearance according to its current phase. * New automatic Golden Hour and Blue Hour calculations. * Completely redesigned iPad experience. * Improved horizon and terrain visualization. * Performance, stability and accuracy improvements. Important: never look directly at the Sun while using AR. When planning an eclipse, perform your visibility check in advance and avoid pointing your device toward the Sun during the eclipse. Coming in Astrian Light 1.7: planets and stars in Augmented Reality.

What’s New in Version 1.4 • New automatic Golden Hour and Blue Hour calculations. • Completely redesigned iPad experience. • Performance and responsiveness improvements throughout the app. • Improved horizon visualization. • Bug fixes and overall stability improvements.
