We present Ha emission line measurements of the W80 nebula complex. A total of 26 regions have been observed inside the nebula with the Dual Etalon Fabry-Perot Optical Spectrometer system at the f/48 Coude focus of the 150 cm RTT150 telescope located at TUBITAK National Observatory in Antalya, Turkey. The intensities, local standard of rest velocities, heliocentric radial velocities and linewidths for full width at half maximum of the H alpha emission lines have been determined from these observations. They lie in the range of 259 to 1159 Rayleigh (R; 1R = 10(6)/4 pi photons cm(-2) sr(-1) s(-1) = 2.41 x 10(-7) erg cm(-2) sr(-1) s(-1) at H alpha), 4 to 12 km s(-1), -3 to -11 km s(-1) and 44 to 55 km s(-1), respectively. The radial velocity measurements show that there are several maxima and minima inside W80. The new results confirm findings in the literature that the complex seems to be rather uniform in terms of radial velocity and no turbulent motion is seen inside the complex. The average value of the calculated emission measure for the region is 3.1 pc cm(-6).
