Attaching the Telescope to the Mount (For C150- HD)

Before you attach the optical tube, make sure that the declination and right ascension clamps are tight. The optical tube attaches to the mount via two rings that are mounted on the tube of the telescope. To mount the telescope tube:

1.Loosen the knobs on the side of the rings. This will allow you to slide the mount- ing rings the length of the optical tube.

2.Locate the two holes on either end of the CG-4 mounting platform.

3.Hold the telescope up to the mount and slide the mounting rings until they are over the holes on the mounting platform.

4.Place the flat portion of the ring over the mount so that the hole in the ring is over the holes of the mounting platform.

5.Thread the mounting screws underneath the mounting platform to secure the rings.

Tighten the knobs on the side of the mounting rings to prevent the telescope from sliding forward or backward. These can be loosened later to reposition the telescope during the balancing process.
