AstroReady vs ARTstronomy Planner

AstroReady helps you know when the sky is worth it. Check local stargazing conditions at a glance, including cloud cover, daylight timing, darkness estimates, and upcoming night forecasts. AstroReady combines weather, sunrise and sunset timing, light pollution estimates, and object visibility so you can decide whether tonight is a good night to head outside. See which planets, constellations, and deep-sky objects are visible from your location, when they rise and set, and how practical they are to observe. Whether you have a telescope, binoculars, or just want to look up, AstroReady gives you a clear answer before you step outside.

One honest GO/MAYBE/NO GO verdict for tonight's sky — tuned to what you're shooting. ARTstronomy Planner tells you — honestly — whether tonight is worth setting up the telescope or driving out to your dark site. No more juggling five weather apps, squinting at cloud maps, and guessing when the moon's too bright to bother. Pick what you're shooting — deep-sky, Moon & planets, or a mixed night out — and get one clear verdict: GO, MAYBE, or NO GO. WHAT YOU GET • Smart verdicts, tuned to your session — cloud cover, moon brightness, seeing, sky darkness, and dark-window length are weighed differently for long-exposure imaging than for a casual night at the eyepiece. • Sky Timeline — an hourly, color-coded forecast strip you slide through like a dial. Total cloud, seeing, precipitation, and humidity for the next two weeks, with sunset, sunrise, and astronomical twilight marked right on the grid. • Live moon phase — a real moon-phase icon and illumination percentage that updates as you drag through time, so you can see exactly how the moon will look at 11pm versus 3am. • ISS pass tracking — visible International Space Station passes appear right on your timeline. Tap one for rise, peak, and set times, direction, altitude, and estimated brightness. • Narrowband-aware scoring — tell it you shoot narrowband, and the app stops marking down nights for a bright moon your filters can cut right through. • Drive-out comparison — see at a glance whether your dark site is actually worth the drive tonight, or if home is just as good. • Bortle sky-quality estimates for any site, home or away, pulled from real light-pollution data. • Ranked target suggestions — the best deep-sky objects or Moon/planet targets for tonight, scored for your gear and your sky.
