I am trying to build a binocular "mirror box" to ease my aching neck. My binos are Oberwerk 20X80's. Does anyone know where you can get a affordable mirror for binos of this power?
One source states: Our PREMIUM mirrors have a wavelength error of ~/= 1 lambda.... While some purchasers have successfully used this mirror with binoculars up to 20 Power, 18x is the recommended limit.
So, what surface accuracy will I need for 20X binos, and where can I get one?
