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 (see Figure 2-14)
and the counterweight(s) are securely installed.
This will ensure that the mount does not move suddenly while attaching
the telescope. To mount the telescope tube:
1.
Make sure that the direction arrow on the mounting platform (Fig 2-7) is
point up towards the sky. If the arrow is pointing downward you must
loosen the DEC locking knobs to rotate the mounting plate and re-tighten
the locking knobs.
2.
Loosen the three mounting screws (do not remove them) on the side of the
telescope mounting platform. This allows you to slide the dovetail bar
onto the mount.
3.
Remove the safety screw located at the front of the dovetail bar.
4.
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 close
to the back of the mounting platform.
5.
Tighten the mounting screw 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.

The visual back is the accessory that allows you to attach all visual accessories to the telescope. The telescope optical tubes
come with the visual back installed. If it is not already on the tube it can be attached as follows:
1.
Remove the rubber cover on the rear cell.
2.
Place the knurled slip ring on the visual back over the threads on the rear cell (Fig 2-9).
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 is free of the rear cell.
