■ LXD 500 Equatorial Mount, including:

— Equatorial head

— 2 washers (1 large and 1 small washer for lock knob

— Counterweight rod with gray counterweight cone
— 2 pcs. 7.5 lb (3.4 kg) counterweights
— 2 slow motion control knobs
— Accessory tray
To assemble the telescope, follow these steps:
1. Preparing the LXD 500 tripod
The LXD 500 tripod (Fig. 2) is shipped virtually completely
assembled from the factory. Once set up, all that is required of
an observer is to attach the accessory tray and adjust the tripod
to the desired observing height.
a.
Setting Up the Tripod:
Remove the tripod from the shipping box and stand the
tripod vertically with the tripod feet down. Grasp two of the
tripod legs and with the full weight of the tripod on the third
leg, gently pull the legs apart to the fully open position
(Fig. 2).
b.
Attaching the Accessory Tray:
Remove the round accessory tray (4), Fig. 2. from the
shipping box.
Unthread the black, star-shaped lock knob from the bottom
of the tray.
Place the threaded rod on the underside of the accessory
tray through the central hub of the extension strut.
Rethread the lock knob onto the accessory tray.
c.
Varying the Tripod Height:
Loosen the black, star-shaped height adjustment knob (5),
Fig. 2, at the base of each tripod leg.
Slide the three inner tripod leg sections out to the desired
height.
Firmly tighten (but do not overtighten) the three height
adjustment knobs (5), Fig. 2.
d.
Collapsing the Tripod:
Remove the accessory tray (4), Fig. 2. Grasp the tripod
head (2), Fig. 2, with one hand. With the other hand, pull
directly up on the central hub of the extension strut, where
the accessory tray (4), Fig, 2, was attached. This action
will cause the tripod legs to move inward to a collapsed
position.
Important Notes on the LXD 500 Tripod:
•
Remove the accessory tray before attempting to collapse
the tripod.
•
If the tripod does not extend or collapse easily, do not
force the tripod legs in or out.
By following the above
instructions, the tripod will function properly.
Forcing the
tripod into an incorrect position may damage the extension
strut system.
•
Do not overtighten the three star-shaped height adjustment
knobs on the tripod legs. "Firm feel" tightening is sufficient.
2.
Assembly of the Equatorial Mount
All the parts required for the Equatorial Mount can be found
(with the tripod) in the LXD 500 Mount shipping box.
The
Optical Tube Assembly (OTA) is shipped in a separate box. To
assemble the mount, follow these instructions:
