Primary Mirror Installation
When installing the primary mirror, take care to align the studs on the underside of the mirror cell with the
corresponding holes in the bottom of the tub. See the mirror cell illustration for help in locating the studs.
If the mirror cell is installed without the alignment studs in proper orientation, the mirror will rest at an angle in the tub,
negating the collimation. When aligned properly, the studs are visible in their holes and can be felt underneath the
tub. When replacing the three mirror cell counterweights, take special care to tighten them equally. Unequal tension
will also affect positioning of the mirror cell and collimation.
