Assembling the OPTICAL TUBE
Remove (2) bolts located on each
side of the OPTICAL TUBE
Align SILVER SIDE BEARING ASSEMBLY
with the same holes and insert the top
bolt first (do NOT tighten yet). Then slide
the BEARING ASSEMBLY up if necessary
and insert the bottom bolt.
Repeat on the other side of the
OPTICAL TUBE.
The position of these BEARING
ASSEMBLIES will determine the balance
point of your telescope and may need to
be adjusted depending on what
accessories are installed on your optical
tube.
