Part I—Set Up

1. General/Location

Before you begin construction, choose a suitable location for your tele-
scope. It is best to build this telescope in a place where you have a clear view
of the skies, a stable footing and sufficient space around you.
Before beginning construction, remove all the parts from the packaging,
and, using the diagram, check to make sure no parts are missing.
NOTE
Important: Only hand-tighten screws. Do not overtighten.

2. Tripod

The tripod legs are preinstalled and already connected to the tripod head (No.
1, 9) and tripod brace (No. 1, 16). Remove the tripod from its packaging and
place it upright, with the feet at the base. Take two of the legs and carefully
pull them apart until they are in the fully open position. The entire weight of the
tripod rests on one leg during this procedure. Then set the tripod upright
again.
Now extend each individual tripod leg to the desired length (No. 4) by loos-
ening the fastening clips (No. 4, X). Tighten the fastening clips to hold the
legs at the desired length, and place the tripod on a hard, flat surface.

A small spirit level placed on the accessory tray (No. 1,
10) may help you set up your telescope so that it's level.
