Assembling your Celestar 18
MOVING THE TELESCOPE IN R.A. AND DEC
Pointing the telescope is done by moving the telescope in right ascension, or R.A. for short, and
declination, or DEC for short (see Figure 2-11). Right ascension corresponds to east/west movement while
declination corresponds to north/south movement. To make considerable directional changes:
1. Loosen the R.A. and DEC clamps on the mount.
2. Move the telescope until pointing in the desired direction.
3. Lock the R.A. and DEC clamps to hold the telescope in place.
For fine adjustment in declination, simply turn the declination slow
motion knob. The DEC clamp does NOT have to be loosened. Once
you have the desired target, stop rotating the DEC slow motion knob. If
the DEC slow motion knob will not turn, the DEC travel arm may have
reached the end of the threaded rod. To correct this, rotate the DEC
slow motion knob in the opposite direction until the travel arm is in the
center of the fork tine (see figure 2-10). Release the DEC clamp and
manually center the object you were looking at. Tighten the DEC
clamp and the DEC slow motion knob will again allow fine adjustments
in both directions. The Celestar Deluxe is equipped with a standard
DEC motor for vibration free fine adjustment. Refer to the section
“Using The Celestar Deluxe Drive” in this manual for information on
operation and maintenance of the DEC motor.
For fine adjustments in right ascension, release the R.A. clamp until the R.A. slow motion knob rotates
freely. Turn the R.A. slow motion knob until the desired object is centered. Once centered, tighten the
R.A. clamp by turning it clockwise. The clamp must be sufficiently locked for the drive motors to engage
and move the telescope.
WARNING: DO NOT TURN THE R.A. SLOW MOTION KNOB WHEN THE R.A. CLAMP IS
IN THE FULLY LOCKED POSITION. DO NOT FORCE THE FORK MOUNT TO SWIVEL
WHEN THE R.A. CLAMP IS FULLY ENGAGED.
The telescope comes equipped with setting circles to help you locate
objects in the night sky. The DEC setting circle is in degree increments
while the R.A. setting circle is in hour and minute increments with a
marker every five minutes. The numbers on the inner circle are for the
northern hemisphere while those on the outer circle are for the southern
hemisphere.
INSTALLING THE R.A. ENCODER
(Celestar 8 Computerized and
Celestar Deluxe 8 Computerized Only)
The Celestar 8 Computerized and the Celestar Deluxe 8 Computerized
are identical to the Celestar 8 and the Celestar Deluxe 8 with the
exception that they comes with the Advanced Astro Master attached.
The Advanced Astro Master is fully installed and tested at the factory.
The R.A. encoder is removed in order for the telescope to be placed in
