Figure 18: Lock the mirror box to the rocker with nylon strips
Make sure the mirror box is locked with nylon strips to the rocker. Also make sure
that the three mirror support bars are evenly placed in the cell. Pick up the mirror and
place it into the mirror cell. Check that the mirror is centered. Wiggle it a bit to insure
that the cell parts are moving freely and adjusted to the float of the mirror.
Next, place the sling between the side pin and the side of the mirror. Rotate the two
lower pin so there is 3-6mm between the sling around the mirror and the side pins.
The side pins should not contact the mirror during observation. If the primary touches
the pins, adjust the sling and/or rotate the side pins that contact it. Tighten the nuts
that hold the side pins.
The mirror-protecting clips should not contact the mirror at all. Keep the clips about
3-6mm above the mirror surface. Place the mirror clips over the mirror and tighten
the top lock nuts.
At this point, the sling should be loosely around the mirror. On the lowest part of the
mirror, which will rest in the bottom of the sling, place a short piece of the provided
Velcro (Magic Nylon tape)
Make sure the sling is in the middle of the mirror, so there is equal amount of glass
above and below it. The magic tape will prevent the sling from slipping off the mirror
when the telescope is pointed straight up. Now, leave the sling loose, you will adjust it
after the telescope is fully assembled.
1. Secure the mirror box to the Rocker with four supplied nylon strips
2. Make sure the 3 support bars are evenly positioned
3. Load the mirror into the cell
Once the mirror is installed, you should use a square cardboard (not provided)
to cover the mirror box up.
