Celestron advanced VX Series Instruction Manual page 6

Your Advanced VX tripod comes with the alignment peg
installed so the polar axis and counterweight bar extends
between two tripod legs If you wish, you can reposition the
alignment peg so the counterweight bar extends directly
over a tripod leg This is a matter of personal preference and
does not affect the stability of the mount Observers at lower
latitudes will prefer to leave the alignment peg between two
legs to avoid the counterweight from making contact with the
tripod leg when the counterweight is in the lowest part of its
swing To change the position of the alignment peg:
Alignment Peg
Tripod Head
1 Use a wrench to hold the alignment peg in place while
using another wrench to loosen the locking nut
underneath the alignment peg
2 Once the nut is loose, you can unthread the alignment
peg and move it to the threaded hole on the opposite
side of the tripod head
3 Thread the peg in until it stops, and back it off until the
flat sides of the alignment peg are square to the tripod
4 Hold the peg in this position with one wrench while
using another wrench to tighten the locking nut against
the tripod head
5 Mount the equatorial head as described above
Attaching the Accessory Tray
The Advanced VX mount comes with an accessory tray
that has holes specially designed for 1 25" and 2" eyepieces
The accessory tray also acts as a tripod leg tensioner to add
stability to the mount To install the tray:
1 Remove the nut and washer from the lower side of the
tripod's central rod
2 Slide the accessory tray over the central rod so that
each arm of the tray is pushing against the inside of
the tripod legs
3 Thread the accessory tray knob onto the central rod
and tighten

Installing the Counterweight Bar
Lock Nut
To properly balance the telescope, the mount comes
with a counterweight bar and at least one counterweight
(depending on model) To install the counterweight bar:
1 Locate the counterweight bar and locking nut from the
box containing the equatorial head The locking nut
should already be threaded onto the end of the
counterweight bar
2 Locate the opening in the equatorial mount on the
declination axis and thread the counterweight bar into
the opening until it is tight
3 Tighten the counterweight bar lock nut fully
Once the bar is securely in place, you are ready to attach
the counterweight
Observing Tip: Since the fully assembled telescope can
be quite heavy, position the mount so that the polar axis is
pointing towards north before the optical tube assembly and
counterweights are attached This will make the polar
alignment procedure much easier
Installing the Counterweight
To install the counterweight(s) that were included with your
mount or telescope kit:
1 Orient the mount so the counterweight bar points toward
the ground
