•Tripod Accessory Tray

•Declination Slow Motion Knob

•Right Ascension Slow Motion Knob

•20mm Plossl Eyepiece

•1 ¼" Mirror Diagonal (Except #31027 & #31056)

Setting Up the Tripod:

1.Locate the tripod head (see figure 1). Attach each leg one by one to the tripod head by aligning the holes at the top of each leg with the holes in the tripod head. Slide a bolt through each of the legs and the tripod head and secure at the other end with a wing nut. NOTE: this may have been pre-assembled at the factory.

2.Now that the tripod legs are attached, stand the tripod up and spread the legs until the center leg support is fully extended.

3.The equatorial mount, which holds the telescope, attaches to the tripod head. On one side of the tripod head there is an “N” which signifies North. This side of the tripod will face north when setting up for an astronomical observing session. Above the “N” is a metal peg about 3/4" high that points straight up. Place the equatorial mount head on top of the tripod head so that the metal peg fits between the two
