Early Grating Test - Neon

This is a very rough test of the grating placing the grating, slit and camera in rough locations. A neon lamp was used as the test source. Slit was open fairly wide, since the room was not dark.

The ball slots were not machined in the proper location, likely due to a mistake setting the 0,0 point on the second operation, on the back side.

Machined a new mirror mount
