Laser primary collimation check

With the secondary mirror centered, but without changing
any of the collimation bolts from where Starizona had set them,
this pattern was displayed with the Glatter holographic collimation
laser. I was startled to see that everything looks very well centered.
The shipping seems to have had serious effects on the centering of the
secondary, but not on the other collimation adjustments. It is now
time for the real test -- an image of the stars.
