When [[:en:telescope|telescope]]s became commonplace, [[:en:setting circles|setting circles]] sped measurements
 
 
 
[[:en:James Bradley|James Bradley]] first tried to measure [[:en:stellar parallax|stellar parallax]]es in 1729. The stellar movement proved too insignificant for his [[:en:telescope|telescope]], but he instead discovered the 광행차[[:en:aberration of light|aberration of light]] and the [[:en:nutation|nutation]] of the Earth’s axis. His cataloguing of 3222 stars was refined in 1807 by [[:en:Friedrich Bessel|Friedrich Bessel]], the father of modern astrometry. He made the first measurement of stellar parallax: 0.3 [[Minute_of_arc#Symbols and abbreviations|arcsec]] for the [[:en:binary star|binary star]] [[:en:61 Cygni|61 Cygni]].
