Page 8: Assembly
Dobsonian Base The base of the XX14i was engineered by Orion to allow quick disassembly into several component pieces, to make it more manageable to transport in a standard size vehicle. Assembly is also fast and easy, thanks to a dozen connecting bolts with attached hand knobs. - Page 9 G (x12) S (x12) T (x12) Figure 7. Exploded view of the XX14i base.

Then use the included insertion tube to push the washer past the Azimuth encoder threads on the bolt and up into the counterbored hole in the wood.

- Page 16 Figure 24. Rather than assembling the entire optical tube and then hoisting it onto the base, some may find it more convenient to mount the lower tube section on the base first, then install the truss tubes and upper tube section. Note: If desired, you can mount the lower tube section on the base before connecting the truss pole assemblies and upper tube section (Figure 24).

Primary mirror center mark drawtube Reflection of primary mirror clip Reflective surface of collimation cap Figure 35. Collimating the optics. When the mirrors are properly aligned, the view down the focuser drawtube should look like this. With the collimation cap in place, if the optics are out of alignment, the view might look something like this. Here, the secondary mirror is centered under the focuser, but it needs to be adjusted (tilted) so that the entire primary mirror is visible. -

Also, when making this adjustment, be careful not to stress the spi- der vanes or they could bend. adjusting the Secondary Mirror’s rotational Position The secondary mirror should face the focuser squarely. If the mirror appears to be rotated away from the focuser, the mir- ror’s rotational position will need to be adjusted. -

An unfocused view of a bright star through the eyepiece should appear as illustrated on the right if the optics are perfectly collimated. If the circle is unsymmetrical, as in the illustration on the left, the telescope needs collimation. -

optics to stabilize. Also, after setting up outdoors, it is a good idea to keep the telescope covered until the Sun sets so the tube does not heat greatly above the temperature of the air. The XX14i comes with a cooling accelerator fan. The fan hastens the equilibration of the primary mirror to the ambi- ent temperature by increasing airflow. - Page 30 objects like planets and double stars. The Moon also takes Jupiter: The largest planet, Jupiter, is a great subject for observation. You can see the disk of the giant planet and higher magnifications well. watch the ever-changing positions of its four largest moons: Deep sky objects, however, typically look better at medium Io, Callisto, Europa, and Ganymede.
