26, Meade 2080 -27- (3) Loosen the Dec. lock (2), Fig. 1, and ro- tate the telescope tube in Declination so that the telescope's optical axis is lined up with its polar axis; i.e. paral- lel to the fork arms. See Fig. 9. Care- ful eye-alignment of these 2 axes is sufficient. Tighten the Dec.…

30, -31- To actuate operation of the electric motor drive, the R.A. lock (see (5), Fig. l)must be in the "locked" posi- tion. As you move from object to object, unlocking and re-locking the R.A. lock each time, the motor drive auto- matically re-actuates each time the R.A. loc…
