Figure 2. Proper operation of the equatorial mount requires that the telescope tube be balanced on both the R.A. and Dec. axes. (a) With the R.A. lock lever released, slide the counterweights along the counterweight shaft until they just counterbalance the tube. (b) When you let go with both hands, the tube should not drift up or down. - Page 6 Focusing the Telescope ments of the six finder scope alignment thumb screws will be needed to get the finder scope roughly parallel to the main tube.
