How does a telescope work different from a camera lense? I’m specifically wondering about magnification. With a camera lense, a longer lense means higher magnification so to get really high magnification it needs a really long lense. With a telescope they just change the eyepiece to get higher magnification and don’t change the length of the telescope.. How is it telescopes can change magnification like that and camera lenses can’t?
