Comparison of nominal sizes of apertures of the Overwhelmingly Large Telescope and some notable optical telescopes

The Overwhelmingly Large Telescope (OWL) was a conceptual design by the European Southern Observatory (ESO) organization for an extremely large telescope, which was intended to have a single aperture of 100 meters in diameter. Because of the complexity and cost of building a telescope of this unprecedented size, ESO has elected to focus on the 39-meter diameter Extremely Large Telescope instead.
