VI Installing the Flip Mirror
*The flip mirror shown here may not be provided for your telescope as a standard accessory.
Loosen the two setscrews on the black ring at the end of the drawtube until the tips of these
screws no longer extend into the inner diameter of the black ring. Slide the flip mirror as
shown in the figure. Tighten the two setscrews on the black ring to hold the flip mirror in
place.
VII Installing the Eyepiece
*The flip mirror shown here may not be provided for your telescope as a standard accessory.
Loosen the setscrew of the eyepiece adapter on the flip mirror. Slide the eyepiece into the
flip mirror’s eyepiece adapter as shown in the figure. When the flip mirror is provided with
the telescope, the eyepiece can be attached on either side; straight thru and right-angled.
Make sure that the light rays passing through the telescope enter your eyepiece by turning
the mirror shift knob.
VIII Balancing the Equatorial Mount
To balance the equatorial mount in declination:
Loosen the R.A. clamp while holding the counterweight bar and turn the telescope tube
until the DEC axis comes to horizontal as shown in the figure. Tighten the R.A. clamp and
loosen the DEC clamp.
Release the telescope gradually to see which way the telescope rotates around the
declination axis. Slightly loosen the knobs on the tube rings (or the knob that holds the
telescope to the dovetail mounting platform if your telescope is equipped with the dovetail
slide bar) and slide the telescope either forward or backward until it remains stationary
when the DEC clamp is loose. Tighten the knob(s) to hold the telescope in place.
