Aligned-ish ITMX HWS

Greg, TJ, TVo

We've aligned the ITMX side and got a retro-reflection back and an image on the HWS, however, I'm not entirely convinced we're looking at the HR surface of ITMX since the beam looks smaller than it did before so we're still investigating that.   We probably still need to do more fine tune adjustment of the alignment, it's a lot harder without the green beams from the end station to help get our injection beam on-axis with the arms.

Attached are the images taken, they're in different spots because I played around with the picomotors on the periscope a bit to avoid some clipping.
