🗓️ Tonight from your yard orange = dark, clear of trees · green = your house/trees · top strip = Moon up
Which real sky survey fills the screen when you zoom in past ~7°. Pan-STARRS is about 4× sharper and shows tiny galaxies way better (south of −30° it falls back to DSS). Infrared sees through dust.
The ISS zips across the Moon or Sun in a second or so (a few seconds when it's low in the sky). It only happens along a path a few miles wide, so this finds the next ones near you and where to drive to catch one. Seestar trick: record a video (or rapid photos) starting 10 s early.
Live dots on the sky: the ISS, Tiangong, Hubble, the newest Starlink group, weather satellites and the ~150 brightest satellites. Bright dots are in sunlight; dim blue ones are in Earth's shadow. Tap a pass to jump the clock there and watch it fly over.
Dates, radiants and rates from the International Meteor Organization calendar. "Per hour" is an estimate for your yard (suburban sky, radiant height, Moon). Tap one to fly to its radiant.
The next lunar and solar eclipses, worked out for exactly where you are. Tap one to time-travel there and see it happen on the sky (the Moon turns red in Earth's shadow, or covers the Sun).
When planets, the Moon and bright stars line up close together in your sky over the next year (Moon ones for the next 2 months). Times are the best moment to look from your yard. Under ~1.1° apart means both fit in one Seestar S30 shot. Tap one to time-travel there.
Comets bright enough for your Seestar S30 right now (brighter than about magnitude 12.8), then the brightest asteroids, with the best time tonight when it's dark and clear of your house and trees. Tap one to fly to it.
Comets and asteroids that will be a lot brighter than now sometime in the next 12 months. Tap to time-travel there.
Orbits from the Minor Planet Center (comets) and NASA JPL (asteroids), updated Oct 12. Comet brightness is matched to real sightings people reported this month (COBS), but comets can still surprise you, brighter or fainter.
When a planet passes in front of its star, the star dims by a tiny bit, usually 1–2%. These are the transits of bright stars you can fully watch from your yard in the next 7 days (dark sky, high enough, clear of your house and trees). With your Seestar, start 30 min early, keep shooting until 30 min after, then measure the star's brightness in each frame. Tap one to time-travel there.
Planet data: NASA Exoplanet Archive (6,445 planets around 4,842 stars, Oct 12 2026). Predicted times can be off by 5–20 min. Turn on 🔭 Show → Stars with planets to see every planet host star on the sky (violet rings).
Pairs of stars that sit right next to each other, often in two different colors. These are the ones up in a dark sky from your yard tonight. Pairs your Seestar can split cleanly are listed first. Tap one to zoom in and see how it looks on the S30's sensor.
Positions and separations: Washington Double Star Catalog (US Naval Observatory). Colors are what the stars look like in a photo.
Finds the exact moments a satellite (ISS, Tiangong, Hubble, Starlinks and thousands more) flies in front of the Moon from your exact spot. A transit path on the ground is only a few miles wide, so type in where you'll be standing.
Math: SGP4 orbits from the latest public orbit data (CelesTrak), Moon and Sun from astronomy-engine with your exact position, elevation and parallax. Times are good to about a second when the orbit data is fresh; recheck the day of.
The next 6 weeks of nights from your yard. Gold is the good stuff: fully dark with the Moon down, the time for galaxies and faint targets. Moonlit nights are still fine for nebulae with your duo-band filter. The first week shows the cloud forecast. Tap a night to jump to its dark window.
A live map of the real sky from where you're standing. Drag to look around, pinch to zoom, tap anything to learn what it is. Zoom into nebulae and galaxies to see real telescope photos at their true spot and size.
Flies you to the best things up over your yard right now, one by one. Tap 👁 first to include ones below the ground too.
