    Comparison of nominal sizes of apertures of some notable optical telescopes For the largest reflecting telescopes on the planet, the horizontal indicates the year built and the vertical direction indicates the size of the mirror measured in meters. Countries which contain several of these telescopes are color-coded for identification.

    People flock to the new David Dunlap Observatory in the 1930s, the second largest reflecting telescope in the world going by a mirror diameter of 74 inches (about 1.9 meters) at that time. Telescopes have grown in size since they first appeared around 1608. The following tables list the increase in size over the years.

    For telescopes larger than 3 meters in aperture see List of largest optical reflecting telescopes. This list combines large or expensive reflecting telescopes from any era, as what constitutes famous reflector has changed over time. In 1900 a 1-meter reflector would be among the largest in the world, but by 2000, would be relatively common for ...

    [4] [5] The telescope had a clear aperture of 40 inches, but was often called the "41 inch" so it would not be confused with the Yerkes 40 inch refractor. [5] Also, the physical diameter of the mirror was 41 inches, even though optical clear aperture was smaller. [4] [5] The 40 inch reflector was of the Ritchey–Chrétien optical design. [6]
