This is the worlds largest known visual binocular. Why binocular and not just a regular telescope? Well, it all has to finish with clarity. apparently when you can use both eyes, you can see much much more detail and pick up light better. The author states in one story that he was able to see a spiral galaxy clearly with a binocular telescope, but couldn’t see it whatsoever with a monocular telescope of the same power.
There is information on several models on the site. look in the best hand column as well for helpful links to parts distributors.
