Found residual smudges on the rear window and two bubbles or chips on the corners of some og the internal elements. There was a larger canine-footprint shaped bubble on one edge on an internal element that appeared to invert the contrast. There was a hairline across one edge of an internal element. I cleaned away the window smudge as best as I could. David and Kim decided we should try squeezing the hairline out--turned out to be a separation air bubble. Tried squeezing the opposite edge first with low torque on the screws on the front surface of the mount. This did not work. Deduced that the air wedge needed to be squeezed together so I gently squeezed on the bubble side and the bubble edged its way out. The canine-footprint bubble enlarged slightly even though it was on the same side as the large bubble. It also changed shape slightly. The other two bubbles/chips did not change. We decided to resolve the large bubble first so I re-installed the filter. Once the filter gets back on temperature and we can observe the sun, we will determine how much improvement the fix made. If there is still some residual degradation, we can then go after the other smaller bubble.
