FOCUS MOTOR FOR SCT & EDGEHD INSTRUCTION MANUAL
2 I ENGLISH
If using a Celestron computerized mount, the focus
motor can be powered and controlled from the
mount. This is done by connecting the AUX port on
the focus motor to an AUX port on the mount using
the supplied cable. If there are no available AUX
ports, the optional Celestron Aux Port Splitter can
be purchased.
Once connected to the mount’s AUX port, the focus
motor can be controlled from the mount’s hand
control. Both the the NexStar+ hand control (requires
version 5.30+ of the firmware) and the StarSense
hand control (requires version 1.19+ of the firmware)
are compatible.
NOTE: If your hand control firmware is not up-to-date, use the
Celestron Firmware Manager (CFM) to update it. This
program can be found at celestron.com/CFM.
The focus control can be accessed by pressing the hand
control’s MENU button, then selecting “Focuser.”
When connected to the AUX port, the focus motor
can also be controlled through the mount from a
computer. This is especially desirable when doing
astronomical imaging, as this will allow control of both
the mount and the focus motor from the computer.
Connect the hand control to the computer using a
USB A-to-mini B cable (not included). One end of
the cable is connected to the USB mini B port on the
bottom of the hand control, the other end is connected
to the computer.
Once connected, you can use most any astronomy
telescope control software that has focuser
control by using the Celestron Unified ASCOM
mount driver, which can be downloaded from
ascom-standards.org.
