Know what's worth observing tonight.
Built for the eyepiece. Conditions, targets, and guides — everything you need before you head out, and everything you need once you're there.
We'll reach out the day it hits the App Store.
You own the telescope. You have the night. But finding the best targets — and knowing what you're looking at — shouldn't require three different apps and a stack of charts.
Your personal
tour of the sky.
Ranked by what's actually visible from where you are tonight. Pick a tour style — Greatest Hits, Stellar Arc, or Max Variety — set your equipment and experience level, and the app builds your night.
The Moon,
named and mapped.
Tonight's exact lunar phase with named seas, mountain ranges, and all six Apollo landing sites pinpointed — the history right where it happened.
Know your sky
before you leave the house.
Hour-by-hour cloud cover, seeing index, humidity, and wind — powered by NWS. Drag the time slider across the night to find your window.
The full catalogs.
Sorted by your sky, right now.
The full Messier and Caldwell catalogs — over 200 objects — sorted by altitude for your location right now. Real-time position, equipment notes, and an observing tip for every single one.
What is that,
actually?
Tap any object type for a full breakdown — annotated diagrams, astrophysics in plain English, and the story behind every structure in the sky. Other apps tell you where to point. This one explains what you're seeing.
Never miss what's overhead —
launches, passes, and celestial events.
Rocket launch countdowns with T-minus badges, mission and payload details, and visibility predictions for your exact location — including which direction to look. Live ISS pass times, meteor showers, planet conjunctions, and more. Everything overhead, tracked in real time.
Yours forever.
