This heavy-duty mount is a smaller version of the sturdy EQ6 mount. It is specially designed for observers who need the steadiness of the EQ6 mount, but find the EQ6 mount too physically demanding. Like the EQ6 mount, this high-precision equatorial mount features engraved aluminum setting circles and a latitude scale, built-in polarscope for Southern Hemisphere use, large R.A. and DEC. locking clamps, electric slow-motion controls on both axes, and retractable counterweight shaft and counterweight.
