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
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.
1 Loosen the locking knobs on the side of the telescope mounting platform. This allows you to slide the dovetail bar on the
telescope onto the mount.
2 Slide the dovetail bar on the telescope tube into the mounting platform of the mount. Slide the telescope so that the back of
the dovetail bar is almost flush with the back of the mounting platform.
3 Tighten the locking knobs on the side of the mounting platform to hold the telescope in place.
Now that the optical tube is securely in place, the visual accessories can now be attached to the telescope.
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.
