E-FocusCF Kit

E-FocusCF - Upgrade kit for Sky-Watcher Crayford Focuser

E-FocusCF Upgrade Kit - designed to be installed on the Sky-Watcher Crayford Focusers. It is used for manual and automatic focusing, as well as to automatically maintain accurate focus depending on changes in ambient temperature. The E-FocusCF is based on the controller Focuser FocusDreamPRO.

E-FocusCF allows you to focus in manual and automatic mode directly from your PC, using standard astronomical programs such as: MaximDL, FocusMax, BahtinovGrabber and other programs that support the ASCOM platform in the focus section.

E-FocusCF also features a proprietary FocusDreamPRO Control panel application that allows you to quickly refocus with the help of the interface buttons or use the left or right mouse button to focus, which can be especially useful for astronomers of fans of planetary photography.

Through the use of microstepping mode of operation of the stepper motor (1/32 steps), E-FocusCF provides high accuracy of focus and smoothness of the movement of the focuser.
