Myst telescope

When I saw this telescope it's design reminded me of the machines in the computer game series Myst. Round shapes and brass buttons. Now what would that big wheel on the right do? What puzzle can be solved here?

In the background is the city of Kufstein and the river Inn. Very muddy due to the heavy rainfall the days before.


And my 100th entry in Flickr! :-)
