Abstract

We have obtained photometry of stars in NGC 2264 with several combinations of H$\alpha$ filters and continuum filters. The main purpose of these observations was to determine the best filter combination for selecting low ma!,s member stars in their Pre-Main Sequence (PMS) stage using H$\alpha$ photometry. A narrow band H$\alpha$ filter (${\Delta}{\lambda}$ = $l0{\AA}$) with any combination of continuum filters showed the highest resolution in the H$\alpha$ photometry.
