I Has anyone made an Aragoscope?

  1. Apr 5, 2016 #1
    From what I understand an aragoscope would be a telescope based on a circular plate that bends light around it's edges into a single focus thus eliminating the needs for large mirrors or lenses.

    I first saw the idea on the NASA website. Why isn't anyone using this?

    Thanks in advance

    because it has to be VERY large to be practical
