    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 QHY10 cameras. My backup mount was then commissioned and the lone Esprit worked on the target. It came out pretty decent I think but more exposure would have been nice.
