Chronocinematograph

Chronocinematograph is an astronomical instrument consisting of a film camera, chronometer and chronograph.[1]^:15[2]^:284–285 The device records images using a more precise timetable for observing an eclipse. It was invented in 1927 by a Polish astronomer, mathematician and geodesist Tadeusz Banachiewicz for observing total solar eclipses.[1]^:15[2]^:284–285 During the same year, Banachiewcz used his device for solar observations in Lapland (Sweden), then in USA (1932) and Greece, Japan and Siberia (1936).[1]^:15[2]^:286

The invention enhanced the precision for determining the time of an eclipse, due to more precisely timed photos of Baily's beads[1]^:15[2]^:284–285, and quantifying the duration of totality. This could not have been observed as closely as before due to the brightness of the sun.[1]^:15[2]^:284–286
