    Francis-

     

    You can buy backpacking compasses (e.g. Ranger, Suunto, etc) with mirror attached. Hold above eye level & use the mirror to sight the object & look down on the compass simultainiously.

    See my home made conversion for an azimuth compass. I first used microscope slides like Greg. Fine for sun reflection, but I wanted Az moon and stars for my patent "quick method" of lunar clearance using the Bygrave (details on request).

    The ladies make up mirror was requisitioned for this important  naval service in the time honoured British way ("borrowed", permanently from my wife's hand bag!).

    So far only tested in the garden.I get 1-2° accuracy. Still to test on bouncing boat.
