You are spot on as far as the setup.
The camera I originally used is a Sony DSC-P92 using Sony's Adapter housing.
This system was fine for the level I was seeking at the time.
Your suggestion of using an actual lens directly on the camera is one that I had begun to investigate. The 14-42 Zoom "Kit" lens is actually made of a hybrid "plastic" and I am not comfortable with coupling this via a step ring. It was recently suggested to me to pick up an old style Olympus Zuiko fixed 50mm lens (Real metal! & $10.00 +/-) and utilze this to couple to the Maxview. Theoretically this optical stack would be more likely to provide a flat and in focus view.
I'm beginning to think that the problem may be the Maxviews design, in that when I look at the Pentax Scopes Zoom lens , the last piece of glass is at the end, which then places it extremely close to the scopes mirror. The Maxview came equipped with an additional lens that screws into the Maxviews exit end. This in my mind mimics the Pentax zoom.
I'm going to call Televue and inquire what they may suggest here.
And if I may ask, how did you "Cut & paste" the pics & diagrams?
