Telescope Basics 20
For fine adjustments in R.A., release the R.A. clamp until the R.A. knob rotates freely. Turn the R.A. knob
until the desired object is centered (see figure 2-12). Once centered, tighten the R.A. clamp. The clamp
must be sufficiently locked for the drive motor to engage and move the telescope.
Do not force the R.A. knob to turn when the R.A. clamp is fully engaged. This may strip the R.A. pinion.
In addition, do not force the fork mount to swivel when the r.a. clamp is fully engaged. This may damage
the drive base.
