Figure 12. To remove the rear end ring, unthread the six screws that connect it to the tube.

Figure 11. Base assembly machine screws set in place, but not yet tightened.

3.Carefully position the assembled structure onto the top baseplate by aligning the holes in the cutouts of the front and side panels to the corresponding threaded metal col- lar inserts on the top baseplate (Figure 10). Insert the base assembly machine screws and tighten (Figure 11). Once this setup is complete you may firmly tighten the six base assembly screws installed in the previous step.

4.Attach the handles to the base. There are three handles, one for each side panel and one for the front panel. Use the 6mm hex key and the large socket head cap screws to install the handles. Each handle is the same so it does not matter which handle is used for any particular panel. Refer to Figure 1 for handle placement.

5.The aluminum eyepiece rack holds three 1.25" eyepieces and one 2" eyepiece in a convenient place on the base, within easy reach while you are observing. The eyepiece rack and its mounting screws can be found in the box with the optical tube. Attach the eyepiece rack on the front panel above the handle. There are two small pilot holes on the front panel approximately 6" apart. Thread the small Phillips-head screws into the holes but do

not tighten completely yet. Place the eyepiece rack on those screws using the wide holes on the rack and slide it downward so the narrow portion is under the screws. Now tighten the screws to secure the rack in place.

6.The XTg series includes a convenient holster to place the hand controller in when not in use. The holster installs on the altitude motor. Locate the two small pilot holes and attach the holster using the small screws until just tight. Do not over-tighten these screws!

7.Now install the azimuth motor connection cable. It is a flat cable that has an 8-pin RJ-45 plug on both ends. Plug one end into the jack on the azimuth motor housing on the top baseplate; plug the other end into the jack labeled AZ MOTOR on the altitude motor housing (Figure 23).

8.Finally, connect the GoTo hand controller. Plug the wide RJ-45 connector on the coiled hand controller cable into the corresponding port on the hand controller. Plug the smaller RJ-12 connector into the port labeled HC on the altitude motor housing.

Assembly of the Optical Tube (XT12g Only)

Both the XT8g and XT10g optical tubes arrive completely assembled from the factory. If you have one of these mod- els, you may skip ahead to the next section, “Connecting the Optical Tube to the Dobsonian Base”.

Due to its large size, and in order to prevent damage to the primary mirror in shipment, the 12" mirror is shipped in its cell separately from the optical tube. Once the primary mir- ror is installed into the telescope, there will be no need to remove the mirror except for occasional cleaning (see “Care & Maintenance”).

1.To install the mirror cell into the optical tube, the rear end ring attached to the lower section of the optical tube must first be removed. This is done by unthreading and remov-
