- The University paid for an extensive restoration and conservation program of the building and the three main telescopes, the Equatorial, the Transit Circle and the Sidereostatic telescope.
- The advantage of a transit circle over a mural circle ( which can measure polar distances ) is that it allows measuring right ascension and declination at the same time.
- The transit circle was capable of determining both right ascension and declination of a star, unlike the more simple and common transit instrument that can only determine the right ascension.
- The meridian was moved around 10 metres or so east on three occasions as transit circles with newer and better instruments were built, on each occasion next door to the existing one.
- The making of circles was shortly afterwards taken up by Edward Troughton, who constructed the first modern transit circle in 1806 for Blackheath, the Groombridge Transit Circle ( a meridian transit circle ).
- The Airy Transit Circles at the Royal Greenwich Observatory ( 1851 ) and that at the Royal Observatory, Cape of Good Hope ( 1855 ) were made by Ransomes and May of Ipswich.

- While the local vertical defined at the Airy transit circle still points to the modern celestial meridian ( the intersection of the prime meridian plane with the celestial sphere ), it does not pass through the Earth's rotation axis.
- He worked at the United States Naval Observatory for 44 years, making distinguished contributions in the field of positional astronomy and pioneered in the field of automation of transit circle observations, which led to results of the highest systematic accuracy.
- In the United Kingdom, the transit instrument and mural circle continued until the middle of the 19th century to be the principal instrument in observatories, the first transit circle constructed there being that at Greenwich ( mounted in 1850 ).
- From the Royal Observatory that houses the great Transit Circle telescope whose crosshairs mark longitude zero, to the Old Royal Naval College, the National Maritime Museum, and the Queen's House, Greenwich contains an impressive concentration of relics that tell the story of Britain's rise to empire through her prowess at sea.
- A 2015 analysis by Malys et al . shows the offset between the Airy transit circle and the ITRF / WGS 84 meridians can be explained by this deflection of the vertical alone; other possible sources of the offset that have been proposed in the past are smaller than the current uncertainty in the deflection of the vertical near the observatory.
