2. Assembly
Carefully open all of the boxes in the shipping container. Make
sure all the parts listed in Section 1 are present. Save the
original boxes and packaging material. In the unlikely event
that you need to return the telescope, you must use the origi-
nal packaging. Note: The EQ-1 Equatorial Mount is packaged
with one empty interior box; the box is included for structural
integrity only.
Your new EQ-1 Equatorial Mount was
Assembling the mount for the first time should take about 30
minutes. No tools are needed, other than the one provided.
All bolts should be tightened securely to eliminate flexing and
wobbling, but be careful not to over-tighten or the threads
may strip. Refer to Figure 1 during the assembly process.
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 bolt through the top of a leg and
through the holes in the base of the mount. The wash-
ers should be on the outside of the tripod legs. Secure
the wing nuts finger-tight. Note that the hinged accessory
tray bracket on each leg should face inward.
2. Attach and tighten the leg lock knobs at the base of the
tripod legs. For now, keep the legs at their shortest (fully
retracted) length; you can extend them to a more desir-
able length later, after the mount is completely assem-
bled.
3. With the tripod legs now attached to the equatorial mount,
stand the tripod upright (be careful!) and spread the legs
apart enough to attach the accessory tray to the three
hinged tray brackets on the legs. The slots in the brack-
ets should be positioned underneath the holes in the three
corners of the tray. Use the three small accessory tray
screws and wing nuts provided to fasten the tray to the
brackets. Do not tighten the wing nuts yet.
4. With the accessory tray attached loosely, spread the tripod
legs apart as far as they will go, until the accessory tray
brackets are taut. Then tighten the wing nuts.
