Utilizing two mirrors, a reflector telescope has a concave primary mirror located at the bottom of the telescope. It reflects inbound light to a pinpoint. A second flat mirror set at 45 degrees located below the aperture redirects the light, creating a focal point toward the eyepiece. 4, record 1, English, - reflecting%20telescope

Les réflecteurs se servent de miroirs au lieu de lentilles pour refléter la lumière sur un foyer : le miroir primaire à l'arrière, gros et incurvé, qui effectue la première focalisation, et le miroir secondaire à l'avant, plus petit, conçu pour rediriger la lumière vers l'œil.

Along with a recorder you will need a microphone. There are two types of microphones that are directional enough for bird song recording the shotgun microphone and the parabolic reflector microphone. The parabolic reflector is actually a combination of a reflector dish typically between 13" and 30" in diameter and a microphone. The microphone is positioned in the focal point of the reflector. This is the area where all of the sound is concentrated and yields an increased sensitivity that cannot be obtained by any other method. 2, record 4, English, - parabolic%20microphone
