It needn't be high-back ... you'd get this advantage by clamping on (?) a head support to the back of the chair which also holds the binocular support arm (or presumaby two arms for bigger binos). It would be a sort of Dobsonian mount for humans.
The binoculars would never have to be moved relative to the observer (except for a small adjustment for different people) - all the movement would be in the chair.
I realise this isn't an original idea (viewed a link once to a US observer who had the whole thing motorised - may have been a commercial device).
The thing is, is it possible to make something like this with a similar amount of work to making a pgm mount, would it be better, has anyone here constructed such a thing?
