On the Implementation of Absolute Meridian Observations in Low Latitude Stations
Published online by Cambridge University Press: 04 August 2017
Extract
Mao et al. (1983) have originally stated that in order to record the transit times of a star at meridian transit as well as at prime verticale transit the chassis of the instrument would have to have two pairs of supports. In my opinion, it may be difficult to develop such an instrument with the required aperture of 20 cm and a focal length of over two meters, especially when the declination system must be very stable.
