    Notes This was the next target for another side by side comparison of the Esprit 150 and AP160 using CCD cameras. Unfortunately, equipment issues prevented me from executing the side by side using 2 identical CCD cameras. Weather and poor seeing conditions kept me from really collecting any great amount of data on the project so I waited until the setup was fully operational from a remote location.
