It is estimated that the two telescopes cost approximately US$187 million to construct, and a night on each Gemini telescope is worth tens of thousands of U.S. dollars. The two 8-meter mirror blanks, each weighing over 22 t (24 short tons), were fabricated from Corning's Ultra Low Expansion glass. Each blank was constructed by the fusing together of and subsequent sagging of a series of smaller hexagonal pieces. This work was performed at Cornin… WebOct 29, 2024 · Here is a look at the steps involved in the making of a telescope. First, the optics for the telescope must be created. This involves grinding and polishing lenses or mirrors to the correct shape. Once the optics are complete, they are placed into the telescope tube. The tube is then aligned so that the optics are pointing in the right ...
