Nevertheless, the first to apply for a patent for this optical device was Hans Lippershey, a Dutch eyeglass maker. Galileo heard about it and, in 1609, built his own variant, and created a telescope for astronomy purposes.<\/p>\r\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-5664401\" src=\"https:\/\/www.optics-trade.eu\/blog\/wp-content\/uploads\/2021\/01\/Cannocchiale_galileiano_Museo_scienza_e_tecnologia_Milano_05.jpg\" alt=\"What Telescope Did Galileo Use?\" width=\"1000\" height=\"666\" srcset=\"https:\/\/www.optics-trade.eu\/blog\/wp-content\/uploads\/2021\/01\/Cannocchiale_galileiano_Museo_scienza_e_tecnologia_Milano_05.jpg 1000w, https:\/\/www.optics-trade.eu\/blog\/wp-content\/uploads\/2021\/01\/Cannocchiale_galileiano_Museo_scienza_e_tecnologia_Milano_05-300x200.jpg 300w, https:\/\/www.optics-trade.eu\/blog\/wp-content\/uploads\/2021\/01\/Cannocchiale_galileiano_Museo_scienza_e_tecnologia_Milano_05-768x511.jpg 768w, https:\/\/www.optics-trade.eu\/blog\/wp-content\/uploads\/2021\/01\/Cannocchiale_galileiano_Museo_scienza_e_tecnologia_Milano_05-930x620.jpg 930w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/p>\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter size-large\">Reproduction of Galileo&#8217;s telescope.
