	22:28:58	Just above right beam bottom of beams near 



Hasleblad Bore Sight

Turned mirror to include video and Hasleblad facing mountains

Photo & Video w/drive startup should show locations of laser spots in photo

*But does this geometry work?

Moved mirror back to point rearward at bore sight target - centered target in center of laser tube 
and took 1 or 2 photos; and - board location in photo should show laser position
