Output Control Via. Select the COM Port of the computer you would like
to use to send commands to the telescope

Autoguider Calibration
In order to properly control the mount, you must calibrate the system. The
exact orientation of the SSDSMI-2, the focal length of the guide telescope
optics, and the speed of the motor drive all affect the calibration. To perform
autoguider calibration:
1. Switch to the Guide tab.
2. Set the X and Y Aggr (aggressiveness) to 8 to start with. Set the Exposure
to 1.0 second. Under Guide Star, make sure the Watch box is checked.
Note: The X and Y Aggr (aggressiveness) controls on the Guide tab allows you
to adjust how vigorously star motions are tracked out in each axis. An aggres-
siveness setting of 10 means that the SSDSMI-2 attempts to track out 100%
of the motion, whereas a setting of 1 means that the SSDSMI-2 only tracks
out 10% of the motion. Usually a setting of around 8 or 9 provides the best
tracking, since it reduces overshoot and helps ignore random motions due to
atmospheric seeing and wind loads. You should experiment to determine the
best setting for your particular telescope.

computer-to-mount communications link if the mount is supported by the ASCOM
platform.
