Sea breeze electronic appliances Tidbits: With increasing diameter telescope, a series of technical problems follow. Hale Telescope lens from weighing 14.5 tons, the weight of the movable part of the 530 tons, and 5 m mirror is weighing 800 tons. On the one hand, the weight of the telescope lens distortion General Assembly to make quite clear, on the other hand, the mirror body temperature unevenness also makes high-end telescope mirror is distorted, thereby affecting image quality. From a manufacturing perspective, the cost of the traditional method of making telescopes almost proportional to the square or cube caliber, so make larger diameter telescope must open up new trails.
