What kind of telescope is used for 3-5 kilometers? It is obviously used to see the mountain view of tall buildings. Please recommend it.

Sirius painter and small black cannon are both good, which is very suitable for picking up cameras outdoors, and the volume is not big enough, which is suitable for photography of grand view stars and celestial bodies. Or you can choose a bird-watching telescope, which is also very suitable. Note that some telescopes are also suitable, but they are upside down. You need a mirror.

If you want to visit the mountain, you can choose binoculars. It can be found in the section of Mufu Astronomical Forum, and many telescopes are also introduced. I suggest you consult inside.

This is a small black cannon, and its effect and quality are recognized.
