Anti-backlash

All mechanical gears have a certain amount of backlash or play between the gears This play is evident by how long it takes for a star to move in
the eyepiece when the hand control arrow buttons are pressed (especially when changing directions) The LCM's anti-backlash features allows
the user to compensate for backlash by inputting a value which quickly rewinds the motors just enough to eliminate the play between gears
The amount of compensation needed depends on the slewing rate selected; the slower the slewing rate the longer it will take for the star to
appear to move in the eyepiece Therefore, the anti-backlash compensation will have to be set higher You will need to experiment with different
values; a value between 20 and 50 is usually best for most visual observing, whereas a higher value may be necessary for photographic guiding
Positive backlash compensation is applied when the mount changes its direction of movement from backwards to forwards Similarly, negative
backlash compensation is applied when the mount changes its direction of movement from forwards to backwards When tracking is enabled,
the mount will be moving in one or both axes in either the positive or negative direction, so backlash compensation will always be applied when
a direction button is released and the direction moved is opposite to the direction of travel
To set the anti-backlash value, scroll down to the anti-backlash option and press ENTER Enter a value from 0-100 for both azimuth and altitude
directions and press ENTER after each one to save these values The LCM will remember these values and use them each time it is turned on
until they are changed
