That's a simple question, As more big businesses and new material /better material to build telescopes have come out the telescopes start to improve, scientists found that there are different combinations that enhance the viewing of telescopes. I don't get why'd you ask this, i could answer it easy and im 13 as its common sense. WOW your brainy!
