Great stuff Phil. Sounds like a handy setup.
I know that when we design these binocular systems we put a lot of effort into making sure that they are easily adjustable for OTHER people - such as those at star parties and general club or society viewing sessions. Should we make the design so easily adaptable?
Should we not just tailor-build them to our own individual specs and be done with it? It'd certainly be easier! I'm in the middle of figuring out how to employ a radio-controlled servo system on my set of 12" binos with mixed differential throw on each side (2 servos per side) such that a new user could come up to the bino and just twiddle two little (or maybe even just one) joysticks to merge their own image. I'd probably have mine built by now if it weren't for this little feature.
Oh well - if we can't share our equipment with others we may as well stay at home!
