5.Orient the equatorial mount as it appears in Figure 1, at a latitude of about 40°, i.e., so the pointer next to the lati- tude scale is pointing to the line at “40”. To do this, loosen one of the latitude adjusting
6.Thread the counterweight shaft into the equatorial mount at the base of the declination axis until tight. Make sure the casting at the top of the bar is threaded clockwise as far as it will go before attaching the shaft.
7.Remove the knurled “toe saver” retaining screw on the bot- tom of the counterweight shaft and slide the counterweight onto the shaft. Make sure the counterweight lock knob is adequately loosened so the metal pin inside the counter- weight is recessed enough to allow the counterweight shaft to pass through the hole. Position the counterweight about halfway up the shaft and tighten the lock knob. Replace the toe saver on the end of the bar. The toe saver prevents the counterweight from falling on your foot if the lock knob happens to come loose.
8.Attach the two tube rings to the equatorial mount using the mounting ring attachment knobs. Place a lock washer, then a flat washer, on the shaft of each knob. With the washers attached, push the knob up through the holes in the top of the equatorial mount and rethread them into the bottom of the tube rings. Tighten the knobs securely. Open the tube rings by loosening the knurled ring clamps.
9.Lay the telescope optical tube in the tube rings. Position the optical tube in the rings so that the
