ADDENDUM TO THE INSTRUCTION MANUAL

On page 4 of the instruction manual, there has been a
change to step 11 of the assembly instructions. It should
read as follows:

11.

The finder scope bracket attaches to the optical

tube over the two pre-installed bolts located near the
focuser. Remove the two round thumbscrews on these
bolts. Do not loosen the two small hex nuts at the base
of the bolts, as they keep the bolts from falling into the
optical tube. The bracket should be oriented so that the
larger, objective lens of the finder scope faces the same
direction as the main telescope.

To connect the finder scope bracket to the pre-installed
bolts, first angle the bracket relative to the optical tube,
as shown in Figure 3, so that the bolts line up with the
slots in the base of the bracket. The bolts will go
through the slots only if the bracket is angled like this
first. Then twist the bracket so it is parallel to the tele-
scope tube while applying downward pressure, until
the bracket seats firmly in place, as shown in Figure 4.
Secure the bracket with the two round thumbscrews.
