Photos of ITM Optics
   On 04/22/19 took a set of photos of the ITM Optics. Shots were taken with the IFO locked at 35w of power. 

   ITM-X photo: Frame #5, 1/160, ISO 200, Focus 1625
   ITM-Y photo: Frame #6, 1/250, ISO 200, Focus 1625

   The shots select were a bit under exposed, which helps show the point reflections, but not so under exposed as to hide the EQ screws, which can be used as a point of reference.
