Chronocinematograph is an astronomical instrument consisting of a film camera, chronometer and chronograph.{{rp|15}}{{rp|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.{{rp|15}}{{rp|284-285}} During the same year, Banachiewcz used his device for solar observations in Lapland (Sweden), then in the US (1932) and Greece, Japan and Siberia (1936).{{rp|15}}{{rp|286}}

The invention enhanced the precision for determining the time of an eclipse, due to more precisely timed photos of Baily's beads,{{rp|15}}{{rp|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.{{rp|15}}{{rp|284-286}}
