Plan a landmark, skyline or moonrise from the right place
Long-distance photography depends on geometry before it depends on zoom. A small change in camera position can change the compass direction to a mountain, tower, bridge or skyline. That determines whether the moon can appear beside or behind the subject.
What the visibility estimate means
The planner adds the camera horizon and subject horizon using an effective Earth radius. A standard refraction coefficient of 0.13 is useful for planning, but the real atmosphere changes. A geometrically visible target can still be blocked by hills, trees, buildings, haze or clouds.
How to use the moon result
The best alignment time minimizes the difference between the moon azimuth and your subject bearing. Check the moon altitude as well: it tells you how high above a level horizon the moon will appear. Visit the full moon and sun planner for rise, set and twilight windows.
Safety
Never point a camera, phone lens, binoculars or a telescope at the sun without certified solar equipment. This tool is for planning only.
