The facility's observatory dome hosts a computer-based 45 cm (1.48 ft) Cassegrain reflector telescope [1] [2] installed at the site in May 2001 and donated by the Japanese government through a cultural aid grant. [3] Before this period, the observatory used a 30 cm (0.98 ft) reflector-type telescope. [1]

This is a list of large optical telescopes. 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.

An example of an older refractor is the Shuckburgh telescope (dating to the late 1700s). A famous refractor was the "Trophy Telescope", presented at the 1851 Great Exhibition in London.
Then with the discovery of optics, with the help of different types of refractor telescopes and later with reflector telescopes. Their use allowed to dramatically increase both the collecting power and limit of resolution , thus the brightness , level of detail and apparent angular size of distant celestial objects allowing them to be better ...
However, other large refractors include a 21st-century solar telescope which is not directly comparable because it uses a single element non-achromatic lens, and the short-lived Great Paris Exhibition Telescope of 1900. It used a 78-inch (200 cm) Focault siderostat for aiming light into the Image-forming optical system part of the telescope ...
