second camera on HAM2 West door aligned, first camera pointing slightly changed
second camera: I aligned the camera on the upper right viewport on HAM2 West door to the calcite wedge on the input of the IO Faraday.
first camera: I maintained a view of baffle HA1 (downstream of IM1) on the camera on the upper left viewport on HAM2 West door, but shifted the view of the camera upward in real space, to capture the double aperture on the beam path to the ISS Array.
To check out the new camera view of the CW, I drove IMs and PRM and I broke the IMC to get a single bounce off of MC2, and relocked the IMC with no issues, and all optics are back where they started, as seen in the attached screenshot, which has the live alignment screen on the left, and the screenshot I took before I started, with it's time stamp, on the right.
images: as seen on the camera, misaligned PRM, as seen on camera: PRM intentionally clipping on the SiC baffle (0.7W): the shot, or an approximation, through the IM1 tower: the shot, showing the bottom of the specialized CW mount through IM1's tower: the CW in it's mount, not the same angle but close.
first two camera images are rotated 90 deg counterclockwise from the display on the CRT
