Great Compact Guide Scope
By James
Rated 5 out of 5

The ZWO 30 mm F5 is a great compact little guide scope. Solid build, easy and smooth focusing. It's made to last. Star capturing is really good. Works well with my ZWO 120 mini, ZWO 174 mini and even my old (and quite frankly, my favorite) SSAG guide cameras.
Great upgrade
