Can you share some images?

Rather than a large achromatic lens in it’s entirety, I have made a panel that carries two 35mm x 35mm square prismatic lenses that I recovered from an old Brewster viewer. This panel is attached by Velcro to the front of the View Magic viewer bringing the viewing distance of my iPad to 150mm. From this, I reckon that the hole assembly of viewer based on two Xperia phones would be about 160 mm cube. At the moment I use my iPad mounted at 150mm distance and it works fine with no synchronisation issues to worry about and the bonus of having a player app that provides automatic panoramic viewing of very wide images.
During my local club meetings, my table top mounted viewer is left running in slideshow mode, throughout the meeting – Happy Days!
If I was to get a second Xperia phone, I would use the View Magic viewer I have as the basis of the new cubic assembly and mount this onto a heavy desktop mike stand; I use such a mounting for my current Xperia and Cycloptal3D viewer.
What would really be good is an 8K tablet!
Seems it could be done with large achromat lenses, instead of the simple prisms on the KMQ, like with the Keystone Telebinocular (which does it horizontally offset instead of vertically in this case). It would be a smaller simpler design, which could compensate for the expensive lenses.
