Attaching the Optical Tube to the Mount

The telescope attaches to the mount via a dovetail slide bar 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

Important! move suddenly while attaching the telescope. To mount the telescope tube:

In order for the CGE mount to successfully locate its declination switches, the mounting platform must be positioned so that the dovetailed locking knobs are on the east side of the mount when polar aligned. In other words, when standing behind the mount facing north, the dovetail locking knobs should be on the right side of the mount.

Attaching the Visual Back

The visual back is the accessory that allows you to attach all visual accessories to the telescope. The CGE 1400 comes with a 2" mirror diagonal that attaches directly to the optical tube without the use of a visual back. To attach the visual back:

1.Remove the plastic cover on the rear cell.

2.Place the knurled slip ring on the visual back over the threads on the rear cell.

3.Hold the visual back with the set screw in a convenient position and rotate the knurled slip ring clockwise until tight. Once this is done, you are ready to attach other accessories, such as eyepieces, diagonal prisms, etc.

If you want to remove the visual back, rotate the slip ring counterclockwise until it separates from the rear cell.
