The Pulkovo Programme for the Study of Visual Double Stars
Published online by Cambridge University Press: 19 July 2016
Extract
The observation of visual double stars at Pulkovo is a traditional work of Pulkovo astronomers started by W. Struve in 1830 at Dorpat (now Tartu). After the Second World War and restoration of the observatory in 1960, the observations of double stars have been carried out with help of 26-inch Zeiss refractor using the photographic technique. We observe the visual binaries which satisfy the conditions of highest accuracy of astrometric reduction: d > 3′, m < 12.0, dm < 1.0, δ>20°.
