(Craig, Doug, Travis, Jason)
We set the camera pointing path by mimicking the camera view using a laser pointer.
An existing fixture was modified and worked well and mounted up well.
We aligned the north side camera view without much issue. The south side required a bit more tweaking of the internal steering mirrors.

The procedure we used involved retro-reflecting a laser pointer through a 1/8" pin hole centered on the viewport. We steered the beam with a couple of turning optics on the fixture. We then propagated the beam through 2 steering optics permanently mounted to the periscope inside of the beam tube and then onto the P-cal target mounted in front of ETMy core optic. 

All P-cal hardware is removed from the vacuum chamber and repackage for storage.
