Field notes
Users can enter latitude and longitude or use device location, then choose a night from tonight through nine days ahead. Sensor shape and the longest side of the camera's field of view help define the setup; saved locations are capped at five, while equipment profiles are built in a separate FOV calculator. The page attributes weather to Open-Meteo, seeing to 7Timer!, and astronomy calculations to suncalc.
