TELESCOPE ASSEMBLY
1. Remove telescope from the carton and Identify all components. READ THROUGH ASSEMBLY
INSTRUCTION BEFORE YOU ASSEMBLE YOUR TELESCOPE
2. Set-Up Tripod
• Select one tripod leg and extend the Tripod Leg Middle Section (7). Using the Tripod Leg Lock Screws
(10) included in the hardware pack, insert a Tripod Leg Lock Screw into the lower brackets on the
Tripod Leg (6). Tighten the Tripod Leg lock Screws so that the Middle Section is securely in place.
Repeat for the remaining two legs.
3. Attach Telescope and Finderscope
• Locate the pre-assembled Telescope Main Tube (14) and Altazimuth Yoke
Mount (12). Note: Before assembling tripod legs to Altazimuth Yoke Mount,
make sure the Accessory Tray Braces (8) face inward. Locate the long
bolts and washers from the hardware pack. Position the mount over the
Tripod Leg (6) as shown (fig. 1). and align the holes in the Tripod Leg with
the holes in the mount. Insert the bolts through the holes at the top of
a Tripod Leg. A washer should be positioned on both outer sides of the
Tripod Leg. Attach a wing nut to the bolt, but do not tighten it all the
way. Repeat on the remaining two Tripod Legs. Once you have
attached all Tripod Legs to the mount, securely tighten all wing nuts.
Remove the Stabilizer Bar Mounting Screw (11) from the hardware pack
and insert it into the opening at the base of the Vertical Stabilizer Bar
(4).
• Locate the Finderscope (1) with pre-assembled mounting bracket. Remove the two nuts located near
the front of the telescope (closet to the eyepiece) and place the Finderscope and bracket assembly
over the exposed screws. The Finderscope Focus Adjustment (16) should point towards the Primary
Mirror (13). Replace the nuts, and securely tighten the Finderscope and bracket assembly in place.
