1. Lay the equatorial mount on its side. Attach the tripod
legs, one at a time, to the base of the mount by sliding a
tripod leg attachment screw through the top of a leg and
through the holes in the base of the mount. The washers
should be on the outside of the tripod legs. Secure the
wing nuts finger‑tight. Note that the accessory tray brack‑
et attachment point on each leg should face inward.
2. Install and tighten the leg lock knobs on the bottom
braces of the tripod legs. For now, keep the legs at their
shortest (fully retracted) length; you can extend them to a
more desirable length later, after the tripod is completely
assembled.

3. With the tripod legs now attached to the mount, stand
the tripod upright (be careful!) and spread the legs apart
enough to connect each end of the accessory tray brack‑
et to the attachment point on each leg. Use the screw and
lock nut that come installed in each attachment point to
do this. First, remove the screw using the supplied screw‑
driver and triangular assembly tool; hold the lock nut
with the triangular assembly tool while turning the screw
with the screwdriver. Then, line up one of the ends of the
bracket with the attachment point and reinstall the screw.
4. Now, with the accessory tray bracket attached, spread the
tripod legs apart as far as they will go, until the bracket
is taut. Connect the accessory tray to the accessory tray
bracket with the three wing screws already installed in the
tray. This is done by pushing the wing screws up through
the holes in the accessory tray bracket and threading
them into the holes in the accessory tray.
5. Tighten the screws at the tops of the tripod legs, so the
legs are securely fastened to the mount. Use the provided
screwdriver and your fingers to do this.
6. Orient the equatorial mount as it appears in Figure 2, at
a latitude of about 40°, i.e., so the pointer next to the lati‑
tude scale (located directly above the latitude lock t‑bolt)
is pointing to the hash mark at "40." To do this, loosen
