I would like, if possible, if you could do a guide/tutorial video on building a versatile telescope system from an 80mm refractor (f/7 if possible) and a binoviewer - for both astronomy and terrestrial/nature viewing. What should a potential user/buyer keep in mind about focus: distances, weight payload, 45degree prisms and which to use etc.
