We observed GSC 1042-2191 three nights, on July 2, 6 and 10 in
2014. and three nights on July 11–13 in 2015 with the 40-cm Schmidt–
Cassegrain telescope equipped with the Apogee Alta U47 CCD camera
at Ulupinar Observatory (UPO) of Çanakkale Onsekiz Mart University
(Turkey). This camera gives image scales of 0.65 arcseconds per pixel
and provides an observed field of view (FOV) of 12 arcmin × 12 arcmin. Several bias, dark and flat frames were taken during the night
of each observation to take into account pixel-to-pixel variations on
the frame. Relevant data for eclipsing system and the adopted comparison stars are summarized in Table 1. The observational log of the
system is listed in Table 2.
