AbstractWe present a time-series BV CCD photometry for an EB-type eclipsing binary NSVS 1908107,a member of the young open cluster NGC 869. The photometric solution was obtained by using the 2003 version of the Wilson-Devinney code. It reveals that the system is a semi-detached binary with the secondary component filling its Roche lobe. The mass ratio was determined to be 0.0590.001. With the physical parameters of the cluster, the masses, radii and luminosities of the two components of NSVS 1908107 are estimated to be M_1 = 10.342.29M_⊙, R_1= 4.650.34 R_⊙,L_1 = 8076371 L_⊙ and M_2 = 0.610.13 M_⊙, R_2 = 2.400.17 R_⊙, L_2 = 105448 L_⊙ respectively. The results show that the secondary component could be a giant or subgiant star with the outer envelope being stripped.
