  Qty.  Description

Truss pole assemblies (captive pairs) 

2. assembly

Now  that  you  have  unpacked  the  boxes  and  familiarized 
yourself with all of the parts in front of you, it’s time to begin 
assembly.  In  addition  to  the  supplied  tools,  you’ll  need  a 
Phillips screwdriver, a small piece of duct or masking tape, 
and two adjustable crescent wrenches. (For base assembly, 
you can substitute a 10mm crescent wrench for one of the 
adjustable crescent wrenches, or use a pair of pliers.)

assembly of the 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. The bolts thread into custom threaded 
receptacles that are embedded in the adjoining baseplate or 
side panel. To ensure that you can never lose them, the bolts 
are held captive in the base when fully loosened, or discon-
nected. While some owners may never have a need to disas-
semble the base for transport or storage, others will appreci-
ate this innovative feature, especially if you observe from a 
remote location and don’t happen to drive a large SUV. With 
its collapsible base and a truss tube design that allows dis-
assembly of the optical tube into smaller sections, this hefty 
14" Dob has the portability and manageability of a smaller 
telescope! 
Refer to 

Figure 7

 during base assembly. When tightening 

screws, tighten them until firm, but be careful not to strip the 
holes by over-tightening. If you use an electric screwdriver, do 
final tightening with a standard screwdriver to avoid stripping.

With a Phillips screwdriver, screw the feet (Q) into the 

1. 

underside  of  the  ground  baseplate  (A)  using  the  feet 
wood screws provided. Insert the screws through the feet 
and thread them into the predrilled starter holes.
Connect the side braces (N) to the side panels (C) using 

2. 

three of the base assembly screws for each panel. The 
brace should be attached to the outside surface of the 
side panel, which bears the SkyQuest XX IntelliScope 
label. The screws go through the holes in the side panels 
and thread into the starter holes in the side braces. Use 
the 4mm hex key to firmly tighten the screws.
Now you will install the captive connecting bolts (G), each 

3. 

of which is already fitted with a black hand knob. There 
are 12 connecting bolts altogether; refer to 

Figure 7

 for 

locations. Start with the front panel (B), which has through 
holes for six connecting bolts. 

 

First, slide a spacer (S) onto a collecting bolt (G). Then 
insert the connecting bolt into the through hole, in the 
direction indicated in 

Figure 7.

 Holding the knob with one 

hand, use your other hand to press a rubber washer (T) 
over the threaded (protruding) end of the bolt. It will be a 
tight fit; you may have to work the washer a bit to get it on.
