Find the exact minute
the light arrives.
Plan the sunset behind your subject, the moonrise over the skyline, or the Milky Way’s arc above the ridgeline — by coordinates, by date, before you ever leave home.
The difference between arriving and witnessing
Sun-behind-landmark alignment
Find the exact date and time the sun sets directly behind a peak, a building, or a bridge tower — calculated from your shooting position’s true azimuth to the subject.
Moonrise over the skyline
Full moon rises due east at sunset — but only a few nights a month line up with a specific foreground. Check moon azimuth and altitude days in advance.
Galactic core visibility & timing
New-moon nights, dark enough skies, and the core above the horizon — cross-reference moon phase against astronomical twilight to find your shooting window.
Polaris altitude for composition
Polaris altitude equals your latitude — frame your circular star trail composition before you commit to a multi-hour exposure sequence.
