Core season here runs roughly February–October; highest May–August.
How this phase changes the frame
—
Moonrise and moonset are worth framing on their own — the low Moon is large, warm and dramatic near the horizon.
For a full lunar disc, the Looney 11 rule suggests f/11 and a shutter near 1/ISO as a starting point; bracket for haze and atmosphere.

Sun, moon and Milky Way directions from your spot, on the shoot date
Rays show compass directions from your location. Map tiles need a network connection; everything else works offline.
Eclipses, meteor showers and sun/moon alignments — computed for your location.
Eclipse dates and types: NASA eclipse catalogs. Visibility from your spot is computed live.
Shower peaks and radiants: International Meteor Organization calendar. Moon interference is computed for each peak night.
Find dates when sunrise, sunset, moonrise or moonset lines up with a compass direction — a landmark, street or ridgeline.
Ten nights from your shoot date, scored on darkness, Milky Way core time and moonlight. Geometry only — clouds and local sky brightness still decide.
Found your night — now find your sky. Hand-picked dark-sky destinations with verified Bortle classes. One tap loads a spot into the planner.
Bortle classes from dark-sky guides and DarkSky International designations; skies vary with weather and season. “Plan a shoot here” sets the location and UTC offset (with US daylight saving) in the planner.
Fresh data for your shoot date and place, fetched in your browser. If a source is unreachable, the planner above keeps working — these cards simply say so.
