Here's the primary mirror glued to the primary mirror mount yoke. Visible in the
corners of the triangular yoke are the pusher or lock bolts for the primary mirror
collimation. The collimation bolt setup is a
push-pull type that has lock bolts next to the collimation adjusting bolts. Also
seen here are the "L" shaped safety brackets used to restrain the mirror if the
silicone adhesive bonding the mirror to the yoke should ever fail.
