With the new Bickely site complete, in 1967, Harris oversaw the installation of a meridian circle telescope at the Observatory as part of an expedition by astronomers from the Hamburg Observatory in Germany.

The building was finished in 1878 and completely restored in 2009 . Contained with it is one of the most important collections of nineteenth-century scientific instruments, featuring a refracting telescope and a meridian circle manufactureed by Repsold.

Chary noted that the star which was observed by astronomer T . Moottooswamy Pillai with a Meridian Circle on February 9, 1864 was not visible when observed in January 1866 but could be spotted on January 18, 1867.

He wrote " Annals of the Observatory of Georgetown College, D . C ., containing the description of the observatory and the description and use of the transit instrument and meridian circle " ( New York, 1852 ).

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.

From the end of 1957 until the end of 1959, three new observation pavilions were built-Pavilion of Large Vertical Circle Askania 190 / 2578 mm, Pavilion of Large Transit Instrument Askania 190 / 2578 mm and Pavilion of Large Meridian Circle Askania 190 / 2578 mm.

While the transit instrument and the meridian circle were used for a star catalogue of 3000 stars that included standard stars, large proper motion stars, variable stars and the like, it is with the new 8-inch Cooke equatorial that he made discoveries of asteroids and variable stars.

A few of the observational instruments went to the new location : a new 30 cm refractor von Repsold, a meridian circle from Pistor & Martins dating from 1868 with 19 cm aperture and 2.6 m focal length, a 6 Zoll ( inch ) refractor from and a Zoll refractor from Merz & Mahler.

As Oort later noted, Kapteyn and his co-workers had not realized that the absorption in the galactic plane was as bad as it turned out to be . Until Oort began his work, he later recalled, the Leiden Observatory had been concentrating entirely on positional astronomy, meridian circle work and some proper motion work.

Later a 5-foot ( 1.5m ) transit and a 3-foot ( 0.9m ) Meridian Circle, fitted with an interchangeable 7-inch ( 17.75 cm ) glass were added, which was the largest at that time in 1839 . In 1842 a 4-inch ( 10 cm ) Comet Seeker was added.
