The knob is a tension fit, so sliding it on holds it in place. As mentioned above, there are two R.A. shafts, one on
either side of the mount. It makes no difference which shaft you use since both work the same. Use whichever one
you find more convenient. If, after a few observing sessions, you find the R.A. slow motion knob is more accessible
from the other side, pull firmly to remove the knob, then install it on the opposite side.
5. The DEC slow motion knob attaches in the same manner as the R.A. knob. The shaft that the DEC slow motion
knob fits over is toward the top of the mount, just below the telescope mounting platform. Once again, you have two
shafts to choose from. Use the shaft that is pointing toward the ground. This makes it easy to reach while looking
through the telescope, something which is quite important when you are observing.

The telescope attaches to the mount via a dovetail slide bar mounting bracket which is mounted along the
bottom of the telescope tube. Before you attach the optical tube,
make sure that the declination and right ascension clutch
knobs are tight. This will ensure that the mount does not move
suddenly while attaching the telescope. To mount the telescope
tube:
In order for the GT computerized mount to function properly,
before installing the optical tube, the mounting platform must be
positioned so that the Declination Index Marks are aligned (see Fig
2-8).
1 Locate the mounting bracket from the box containing the equatorial
mount head.
2 Attach the mounting bracket to the tube rings so that the tapered (narrow) end is against the bottom of the tube
rings.
3 Loosen the hand knob on the side of the
CG-5 mount.
4 Slide the mounting bracket that is attached
to the bottom of the tube rings into the recess
on the top of the mounting platform (see figure
2-9).
5 Tighten the telescope mounting screw on
the CG-5 mount to hold the telescope in place.
6 Hand tighten the mounting platform safety
screw until the tip touches the side of the
mounting bracket.
NOTE: Never loosen any of the knobs on
the telescope tube or mount. Also, be sure
that the open end of the telescope is
pointing away from the ground at all times.
