Now that you have unpacked the boxes and familiarized your-
self with all the parts in front of you, it's time to begin assembly.
The optics of the XT6i, XT8i, and XT10i are already installed
inside the tube, so most of the required assembly concerns
the Dobsonian base. Skip to "Assembly of the Dobsonian
Base." For the XT12i, the primary mirror is shipped in a sepa-
rate box and will have to be installed in the optical tube. If
you purchased the XT12i, start with the next paragraph for
instructions on how to install the mirror into the tube.
assembly of the optical tube (Xt12i only)
In order to prevent damage to the primary mirror in shipment,
it is shipped in its cell separately from the optical tube. To
install the mirror cell into the optical tube, the rear end ring
attached to the optical tube must first be removed. This is
done by unthreading and removing the Phillips-head screws
that connect the end ring to the tube (Figure 1.2), and then
pulling the end ring off of the tube.
Warning: Once the rear end ring is removed from the tube,
the raw edge of the tube itself will be exposed. Be careful
not to cut or otherwise hurt yourself on the tube's edge.
Also be careful not to pinch your fingers when attaching
the assembled mirror cell onto the tube.
