Rigidity is, for sure, the most important feature of a guidescope, with (probably) field of view being […]
This month we tested a versatile focus motor manufactured by Lunático; the so-called Tarsier. It is a fully autonomous motorized focuser system, without the need for a computer and compatible with most of the focusers on the market. Let’s see how it works.
