What Premium adds
Alerts
A phone notification, or a Telegram message, when tonight is a GO, which nights ahead are good, or a meteor shower peaks. You choose the time and what to hear about.
Your own GO / NO-GO rules
Set the cloud, moon, wind and dark-hours limits that suit your gear. The planner and your alerts both use them.
10 saved sites
Keep a home sky, a dark site and the places you travel to, and switch between them. Check them all at once with the multi-site planner, and have alerts watch any of them. Free keeps one.
10 gear setups
Save every camera and scope combination you own, with its filters. Free keeps one.
Sync across your devices
Your saved sites, gear, targets, logs and scoring rules follow your licence key to every browser and phone, so you set them up once.
50 saved targets
A long wish list with status, notes, goals and logs. Free keeps 10.
What stays free
- Tonight's GO / NO-GO verdict, hourly weather, moon and weather-model check
- The planner, dark calendar, timeline and Milky Way pages
- Every target page, with 1,000+ objects, the sky profile and filter-aware advice
- Integration goals, suggested hours and session logs
- All the learn guides and calculators
- One saved site, one gear setup and 10 saved targets, kept on your device
Your saved targets, sites, gear and logs stay on your own device. Nothing is synced to a server, so there is no account to make.
