2.4.2 Installation of the Secondary Mirror Cage
Here is the installation procedure:
•
Make sure that the primary mirror is fully protected with a mirror box cover,
which can be as simple as a square cut out of cardboard.
•
Loosen the wing nuts on all the knob screw as much as possible, but make
sure they are still fully engaged on the bolts.
•
Hold the secondary cage up, and slide one of the slots on the upper ring into
the top knob bolt of one truss pair. Make sure you slide the slot into the space
between wing nut and the truss tube ends.
•
Then slide an adjacent slot into the knob bolt of the corresponding truss pair.
•
Then slide the remaining two slots into the rest two knobs bolts at the same
time
•
Finally tighten all knobs & wing nuts.
