Bortle + SQM
Darkness context before you leave the city.
Free dark-sky map
Start with the map. Decide with Pro.
The public map is the acquisition surface: light pollution, Bortle/SQM, cloud, moon, aurora, ISS, Starlink and accommodation hooks in one place. Pro turns that into saved spots, alerts and best-night decisions.
Moon + cloud
Know if contrast and cloud risk make the trip worthwhile.
ISS + Starlink
Free event hooks for casual users and photographers.
Source labels
Separate live data, estimates and editorial guidance.
Founding Pro push
Use the free map to find dark. Use Pro to decide whether to go.
Pro is for the night you are actually considering: top-three nearby candidate sites, distance-aware score, best-night scan and a session brief before you commit time, gear or fuel.
