My 10x50 binoculars on a monopod are my most used astronomy gear but of course are a bit of a strain near the zenith. I have tried the various mounting options with a zero gravity chair but like to be more on my feet and mobile. A right angle binocular would be ideal but are not available in the lower powers. A mirror mount would be quite a bulky thing, and the large first surface mirror involved looks quite vulnerable if not used on a table or surface of some sort.
Using my 9x50 raci finder the other night made me wonder if two of these could be coupled together to make a reasonable binocular. If the crosshairs were removed and each was held in a couple of finder rings screwed to a mounting of some sort, it would be possible to adjust the IPD and collimation via the ring screws. I'm presuming that finder manufacturing tolerances are tight enough to use two finders from the same company.
I've searched around to see if this has been covered before but only found binoculars converted to finders, not the other way round.
