FAQs
Frequently asked questions
You've got questions. We've got answers.
How is this different from a planetarium or a planner I already use?
Planetariums show you everything. Planners rank a thousand rows. Either way you're still second-guessing a spreadsheet at 11pm. Clear Night Coach isn't a bigger catalogue — it's the one thing a catalogue never gives you: a decision, with its working shown so you can trust it or overrule it. Use it alongside your planetarium, not instead of it.
How accurate is it — where do the numbers come from?
Altitudes, dark windows and framing are computed on your machine from JPL ephemerides. The weather is a forecast and treated as one. The AI only writes prose; a wrong figure is caught before display.
Is it really free? What's the catch?
Yes. The pick, shortlist, verdict, reasoning and Check a Target are free forever. No account, sign-up or trial timer. Pro is optional and keeps the lights on
Do I need an account? What happens to my data?
No account, no sign-up, no telemetry. Settings and logbook live in a folder on your machine and export as one backup file. Internet is used only for the forecast and Pro's live narration.
Can I use Clear Night Coach without internet?
Yes. Your saved settings and logbook stay on your machine, and the core observing tools work at the dark site. You’ll need a connection to refresh the weather forecast or use Pro’s live narration.
Which platforms does it run on?
Windows, Mac and Android. The Mac version runs on Apple Silicon Macs (M1 or later) with macOS 14 or later, and the Android app is on Google Play. There is no iPhone version yet; one is in the works.
