I've installed a Watec camera/lens combo on the HAM2 West door, which looks at the baffle downstream of IM1, IO straight baffle HA1.  In order to get a view of the baffle, I used one of our camera housings that sits at an angle to the viewport, and is smaller in diameter than the viewport.  The new position of IM1 (it moved in the +X and -Y directions) and the new Viton under the SiC baffle on IM1 combine to reduce the view of the aperture on HA1.  The edge of the aperture that's closest to IM1 is so close the the IM1 SiC baffle that it's not clear to me that all of the front edge of the baffle aperture is in the camera view, however the baffle is thick, and I can identify the back edge of the baffle aperture on that side.  The mounting system inside the camera housing cannot move toward the viewport even if all screws were to loosen, and the camera/lens combo is on a swivel ball head and is mounted so that in every possible position the lens cannot reach the viewport.  The camera view is rotated 90 degrees.  The first attached image is rotated to correct that, and the second image is true to what is seen on the CRT display, with +Z direction being toward the right in the image, and the third image is a full res image of the aperture (large file, also corrected for +Z = up).
