ISS orbit data: CelesTrak TLE propagation (satellite.js).
Upcoming astronomy events
Meteor showers, conjunctions, eclipses, and opposition dates with visibility notes.
Visibility labels indicate hemisphere coverage and useful observing windows such as "Best before dawn".

Event visibility catalog: Stellara curated astronomy events database.
Astronomy weather and moon conditions
Cloud layers, humidity, wind, seeing, transparency, moon phase, and visibility.
Weather data update time: --
Search your observing site and decide quickly: deep-sky session, lunar/planetary session, or wait for better conditions.
Practical note: high humidity can increase haze, strong winds can make tracking unstable, and moonlight can brighten the background sky.
Weather models: Open-Meteo (cloud, wind, humidity, visibility) + 7Timer (seeing, transparency). Astronomy data: AstronomyAPI for body positions, phase imagery, and local star charts, with SunCalc server-side for rise/set, solar noon, day length, and twilight.

Local star chart
Generated sky chart centered on the overhead sky for your selected observing coordinates.
Generated with AstronomyAPI Star Chart Studio. This chart is a planning reference for the selected date and overhead sky center, not a live interactive sky map.
Light pollution map
Interactive sky-brightness view centered on your selected observing coordinates.
Map credits: LightPollutionMap.app. Light-pollution layers and overlays may be approximate or outdated, so use this as a planning reference rather than a real-time measurement.
Advanced analysis
Premium observing guidance derived from the forecast, moon timing, and sky clarity data.
Advanced observing analysis will appear after you select a location.
Stellara Pro unlocks a compact planning summary once real weather and astronomy data are available.
