What is a telescope?
A telescope or spotting scope can just cover a greater distance than a monocular or binocular. With a spotting scope or telescope you can view an object up close and with one eye.
Telescope: far distances and yet so close
Because a telescope or spotting scope is usually supplied on a tripod, the image of the telescope becomes stable and you can view the object well.
The telescope or spotting scope can be used well for spotting deer at large distances. Because you are at a great distance, the animal cannot see you quickly and you can enjoy an animal in the wild at a distance, but also very close.
The size and weight are higher than with normal binoculars or mono viewers, but the distance you can look at is a lot bigger. With this you often end up in a place where you stand still longer to spot what you want to see and then you move to a new location for the next spot.
A telescope or a spotting scope is also a great solution for spotting aircraft. The diameter of the lens is often a lot larger than with binoculars or mono viewers, so that more light can be admitted for a clear view.
