2.Lock the R.A. clamp to hold the telescope in place.

3.Release the DEC clamp and position the telescope so that it is parallel to the ground.

4.GRADUALLY release the telescope tube to see which way it “rolls.”

5.Loosen the screws that hold the telescope inside the mounting rings and slide the telescope either forward or backwards until it remains stationary when the DEC clamp is released (see figure 2b).

6.Tighten the screws that hold the telescope in the mounting rings.

The telescope is now properly balanced in declination.

Attaching the Finderscope (for #21077, #21016 & #31056)

To install the finderscope onto the telescope you must first mount the finderscope through the finder bracket and then attach it to the telescope. Toward the front of the telescope tube, near the focusing assembly, there is a small bracket with a set screw in it. This is where the finderscope bracket will be mounted. To install the finderscope:

1.Slide the rubber O-ring over the eyepiece end of the finderscope and roll it 2/3 of the way up the finderscope.

2.Insert the eyepiece end of the finderscope through the bracket until the O-ring presses tightly between the finder and the inside of the bracket.

3.Tighten the three adjustment screws until they make contact with the finderscope body.

4.Locate the mounting bracket near the front (open) end of the telescope.

5.Loosen the set screw on the mounting bracket on the telescope.

6.Slide the finder bracket (attached to the finderscope) into the mounting bracket on the telescope.

7.The finderscope bracket will slide in from the back. The finderscope should be oriented so that the objective lens is toward the front (open) end of the telescope (see figure 3).

8.Tighten the set screw on the mounting bracket to hold the finderscope in place.
