I am considering building a 127mm f12 folded refractor from parts i already have, but i will need two high quality well coated flat mirrors for bouncing the light path within the 'box'. Given that the objective is 127mm, the flat mirrors do not have to be very big. Anyone know of a source of high quality flat mirrors? I am tempted to just use newt secondary ellipical mirrors and blacken the unrequired ends with flocking. These are readily available, i just need the minor axis, and can use secondary stalks to mount them and adjust. Anyone see a problem with that approach?
