A.
Locate the Gennan equatorial mount and the tripod legs along with the tripod mounting hardware and
the tripod accessory tray.
I.
Lie the tripod head (#38) on its side. Attach the three tripod legs (#20) one by one to the tripod
head with the bolts and wing nuts (#34). Do not overtighten the bolts but
just
make them lightly
finger tight. Remember to have each tripod leg in the right orientation with the tripod tray bracket
(#I 9) facing inward.

you wish) and for maximum rigidity.
We
suggest you keep it at the lowest height for assembly (you can raise it

the tripod legs through the holes for the height
NOTE-this
may have been assembled at the
factory.
3.
Now set the tripod with the equatorial mount attached in the standing position by spreading the
legs apart far enough for the tripod accessory tray (#32) to fit.
You are now ready to install the tripod accessory tray (#32). The tripod tray

Before proceeding further, locate knobs # 16, #22, #24 and #28 and tighten all

of
the leg brace and thread them into the accessory tray.

I. Locate the declination cable holder (#13). Locate the declination cable (the shorter
cables) and attach the cable (#18) to the cable holder by tightening the thumb screw on the cable
end. The thumb screw should be tightened down hard on the flat surface

You may reverse the position orientation
of
the Declination cable to suit your preference
desired.
3. Locate the right ascension cable holder (#27). Locate the right ascension cable (#31) and attach it
the same way as the declination cable was attached in the last section.
4. Slide the counterweight shaft (#29) through the counterweight (#30).
Use the counterweight lock
(#36) to Jock the counterweight in place. By holding the counterweight in one hand, thread the
counterweight shaft clockwise into the equatorial mount (#33) as shown in figure
C.
Now you are going to put the telescope optical tube (#11) onto the equatorial n:tount (#33).
