While viewing an object in the eyepiece, observe the responsiveness of each of the four arrow
buttons. Note which directions you see a pause in the star movement after the button has been pressed.
Working one axis at a time, adjust the backlash settings high enough to cause immediate movement without
resulting in a pronounced jump when pressing or releasing the button. The hand controller will remember
these values and use them each time it is turned on until they are changed.

backlash steps here. The maximum steps are 9999.

Stop Tracking will stop the mount when it passes the meridian. Telescope Flip will flip the telescope and

tracking and the OTA could hit the tripod leg if the mount is not monitored.

Use this function to adjust the light intensity of iEQ45 illuminated polar scope. If you have an
illuminated-reticule eyepiece and it is supported by Go2Nova hand controller, use this option to adjust its
