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.

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).

Reflective surface Primary mirror of collimation center mark drawtube Reflection of primary mirror clip 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. -

Altitude Out of collimation Collimated Figure 41. A star test will determine if a telescope’s optics are properly collimated. 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. -

idea to keep the telescope covered until the Sun sets so the tube does not heat greatly above the temperature of the air. The primary mirror supplied with this XX14i IntelliScope has a new, lower-mass design with a convex, ribbed back. This design promotes more rapid cooling and does not require a complicated multi-point support structure as the previous, flat- back mirror did. - Page 30 Deep sky objects, however, typically look better at medium watch the ever-changing positions of its four largest moons: Io, Callisto, Europa, and Ganymede.
