IOTA Alignment with Integrated Optic Combiner:
 
New Quick Method


               beam-
              splitter     dichro
to ccd ----------/------------/---{---------- to telescopes
                 |            /   {--> retro
                 |            /
                eye           fiber

Repeat cycle for each beam. Steps 1-6 before dark; step 7 with star.
All visual adjustments are via alignment telescope at end of long table.

1. Align optics toward telescope.

2. Align fiber. 3. Align CCD:coarse. 4. Align CCD: fine. 5. Align Picnic (3 beams). 6. Acquire star.
