Adjusting The Mount; Attaching The Dec Slow Motion Knob - Celestron C4.5 Instruction Manual

ee A
Adjusting the Mount Before going further, it is a good idea to adjust the mount to a more conve-
nient position for attaching the accessories and telescope. The mount is
shipped with the declination (DEC) setting circle in the 0° position and the
mount in the 90° position.
1. Loosen the altitude locking clamp (see figure 2-4).
2. Swing the mount until the latitude scale points to the latitude of your
observing site (see figure 2-4). Tighten the altitude adjustment screw.
3. Tighten the altitude locking clamp to hold the mount in place.

until the declination circle reads 90°. Swing the mount so that the DEC
Figure 2-4 slow motion shaft points up. This allows for easy access to the DEC slow
motion knob when looking through the telescope.

Attaching the DEC With the mount securely in place, you are ready to attach some of the
Slow Motion Knob accessories (the telescope tube is added last). Start with the declination
(DEC) slow motion knob. The DEC slow motion knob allows you to make
fine adjustments in the direction the telescope is pointing (once it is attached
to the mount). The shaft that the DEC slow motion knob fits over is toward
the top of the mount, just above the declination setting circle. To install the
DEC slow motion knob:
1. Loosen the set screw on the DEC slow motion knob until the tip of the
screw no longer extends into the inner diameter of the sleeve. You will
need a standard flat-blade screwdriver (or an Allen wrench) to perform
this task.
2. Orient the metal sleeve so that the set screw is over the flat portion of the
DEC shaft (see figure 2-6).
3. Slide the metal sleeve on the DEC slow motion knob over the DEC shaft
(see figure 2-5).
4. Tighten the set screw to hold the DEC slow motion knob firmly in place.
