ASA 3" OK3Z Focuser Only (Controller/Software Not Included)

The ASA 3" model OK3Z Focuser, Only (Controller/Software Not Included) is an electronic motorized focuser for a 3" barrel, made by ASA. This particular model (the Z model) is a focuser designed for heavy payloads and imaging accessories over 13.2lbs (6kg) and has been tested up to 44.1lbs (20kg). The OK3-Z includes an internal gear rack which greatly improves stability and repeatability of focus positions, a feature which is crucial for remote operation. The focuser works in conjunction with ASA's new and improved electrical controller ensuring finer motor steps and smoother acceleration. Note: The optional electric controller can be ordered from OPT. The ASA OK3-Z and enlarged focuser tube counter plate will be the ideal focuser unit to use on all ASA astrographs with 16inch aperture and above.

The OK3-Z focuser can be controlled from within ASA's telescope control software, Autoslew. Note: The optional Autoslew software can be ordered from OPT. This focuser model can be accessed by some third party software applications.
