Long distance observations

A typical example of long-distance observation. The Tatra Mountains as seen from the Łysa Góra, in southeast Poland, at a distance of about 200 km (120 mi).

Long-distance observation is any visual observation, for sightseeing or photography, that targets all the objects, visible from the extremal distance with the possibility to see them closely. The long-distance observations can't cover:

The celestial objects, because they are always far away from the observer. Usually, the subject of their observations is Astrophotography.
Aircraft spotting, as it refers mostly to aircraft observed in the vicinity of the airport only.
Satellite watching, which is the subject of Astrophotography.
