Use the three tightening screws located at the

bottom of each leg to secure the extended legs

in place.

To set up the tripod, spread the legs outward until

they are fully extended. Extend the center portion of

each of the three tripod legs down 6-12".

All three legs should be the same length to

provide a level platform for the telescope.

Locate the equatorial mount and place the base of

the mount through the hole in the center of the

tripod mounting platform.

Properly assembled, the accessory tray should

appear as pictured above.

From underneath the tripod mounting platform,

thread the mounting nut into the threaded hole on

the bottom of the equatorial mount.

Thread the latitude adjustment screw into the

equatorial mount until the screw is touching the

inside of the mount.
