A great refractor was often the centerpiece of a new 19th century observatory, but was typically used with an entourage of other astronomical instruments such as a Meridian Circle, a Heliometer, and Astrograph, and a smaller refractor such as a Comet Seeker or Equatorial.
The Double Refractor aside, there is also the 16 cm Schröder Refractor, which was used for the Cordoba Durchmusterung (the southern extension of the Bonner Durchmusterung).
Some of the telescopes produced by Howard Grubb include the 27-inch refractor for the Vienna Observatory (1878), the 10-inch refractor at Armagh Observatory (1882), the 28-inch refractor at the Royal Observatory, Greenwich - the UK's largest refractor (1893), and the 10-inch refractor at Coats Observatory, Paisley (1898).
Between 1847 and 1852 Whipple and astronomer William Cranch Bond, director of the Harvard College Observatory, used Harvard's Great Refractor telescope to produce images of the moon that are remarkable in their clarity of detail and aesthetic power.
In 1877 while the McCormick Refractor was still in Cambridgeport, Alvan Clark used it to verify the discovery of the moons of Mars the night after the discovery observations were made by Asaph Hall with the Naval Observatory refractor.
The observatory formerly included a twelve inch (30 cm.) refractor telescope built by the Alvan Clark firm in 1916 for the Czarist government of Russia.
The history of the Stull Observatory goes back to 1863, when the astronomer William A. Rogers ordered and donated a 9 inch refractor with the American optician Henry Fitz.
Subsequently, in the year 1887, he provided the same observatory with a 13-inch refractor to enable it to take part in the International Photographic Survey of the Heavens.
The facilities include a 24-inch Boller and Chivens reflector with a CCD and retrofitted with a DFM control system, a 12" Fitz/Clark refractor, a 6" Alvan Clark refractor, a Hale Spectrohelioscope, and six Meade 8" SCTs.
