Abstract
This paper describes the acquisition of CCD-derived photometric data from two eclipsing overcontact binaries, NY Boo and V508 Cyg. Astrophotography filters (blue and green) were used, but measurements were transformed to the Johnson-Cousins standard using the reference star fields in M67. Aside from producing period-folded light curves for both variable systems, new times-of-minimum were added to other literature values in order to update each ephemeris.
