Sky-Watcher EQ-6 equatorial mount The Sky-Watcher EQ-6 equatorial mount is the first of its kind, and is top of our range of equatorial mounts. It is a precision instrument capable of carrying massive payloads (up to 25kg) but at the same time is very reasonably priced. The mount is excellent for vis...
A finder scope is a little telescope that mounts on your main telescope. Today, we cover red-dot and Telrad finders. These devices, also called unit-power finders because they don't magnify an image, are much more intuitive for beginners and in many cases much easier to use. Especially in dark sky....
