Under the HKα project, 150 dF to dM stars are systematically studied with the REOSC DC spectrograph, mounted on the JS telescope at CASLEO. However, this survey requires 20 full observing nights per year. In order to reduce the observation times, as well as to study the activity of stars with V > 12 mag, a new observational strategy is analyzed. In this work, the REOSC DS is used with the 1200 l/mm grating covering only the Ca II lines and the continuum nearby. An intercalibration between the Mount Wilson indices obtained with both configurations is presented. In future works, the longlist spectra will be incorporated into the extensive database of the HKα project.
