6. SETTING PARTS
6.1 Tripod
• Set up telescope where there is a clear view of the sky and the ground
is stable.
• Fully spread the tripod legs apart and set the height of tripod by
loosening the tripod leg lock knobs so it is at the appropriate height.
• Level the top of the tripod by adjusting the height of the three tripod
legs
• Attach the accessory tray to the tripod by placing the tray under
the leg spreader bars, then align the three built-in channels with the
spreader bars and tighten the hand knob to secure it in place
6.2 Mount
• Place the mount onto the tripod so that the base of the mount is on
top of the tripod.
a) Best practice: place the mount so that the counterweight shaft
will be on top of one of the three tripod legs. By doing so, the
telescope will be more stable and not tip over.
• Secure the mount to the tripod by tightening the large Azimuth lock
knob to a firm feel.
• Thread in the latitude adjustment screw to the back of the mount.
• Thread the counterweight shaft into the declination axis till it stops,
and remove the safety knob on the bottom of the shaft.
• Slide the counterweight up onto the shaft and secure the
counterweight by tightening the counterweight lock knob.
• Re-install the safety knob back onto the counterweight shaft.
• Install the slow-motion control cables and make sure that the slow-
motion cable thumb screws are placed against the flat spot on the
shaft and tighten the thumbscrew on each cable to a firm feel.
6.3 Ocular Tube Assembly
• Place the optical tube onto the saddle plate and tighten the OTA lock
knobs to a firm feel.
6.4 Viewfinder Alignment
• Point the telescope at a land object that is at a far distance during the
daytime, such as a distanced stop sign.
• It is best practice to use a higher power eyepiece to align the
telescope.
• Look through the eyepiece and center the object in the eyepiece.
• Focus the telescope by turning the focus knob till a clear and sharp
image appears.
• Loosen one of the view finder’s alignment screws and tighten another
at a time till the crosshair is overlapping the same object.
• To further align the optical tube and viewfinder, repeat this procedure
at night by pointing at a celestial object such as the moon.
• For a reflector, slide in the eyepiece into the eyepiece holder and
tighten the eyepiece lock knob to a firm feel.
a) Due to the design of the OTAs, the location of the eyepiece
on a refractor will be closer to the ground than the location of
the eyepiece on a reflector, adjust the height of the telescope
accordingly.
• For a refractor, first install the diagonal into the optical tube, and
secure the diagonal by tightening the diagonal lock knob.
• Slide an eyepiece into the diagonal and secure the eyepiece by
tightening the diagonal lock knob.
• Install the view finder and secure it by tightening the view finder lock
knob to a firm feel.
6.5 Balancing
• Balancing Right Ascension Axis
a) Loosening the right ascension knob and rotate the telescope
until the counterweight shaft is pointing horizontally.
b) Slide the counterweight after loosening the counterweight
lock knob till the telescope is balanced on the right ascension axis.
