Two recently discovered variable stars (CzeV134 = GSC 3682 0018 = USNO-A2.01425-1870026 and CzeV135 = GSC 3682 2051 = USNO-A2.0 1425-1825909 = V1094 Cas),which have been identified in the field of the W UMa variable star BS Cas, arestudied in the present paper. The phase curves and finding charts for thesestars are presented. The ephemeris and other photometric parameters werecomputed.  The phenomenological features indicate that the first star (CzeV134) isprobably a low-amplitude RRc Lyrae - type variable star with the period P =0.419794\pm0.000029 d and the initial epoch T0 = HJD2453236.50412\pm0.00056.The amplitude and the shape of the light curve are variable possibly indicatingthe Blazhko phenomenon. The second star (CzeV135) was classified as an EW-typebinary system of subtype A. However, a {\beta} Lyrae type may not be excluded,as various classification parameters lie in a range of overlapping values forboth classes. The period P=0.51429090\pm0.12 d and the initial epoch T0 =HJD2454543.7920\pm0.0006. The O'Connell effect is clearly visible. There areslight changes of this effect, noticeable while comparing different seasons ofobservations. O-C diagrams for these stars were analyzed.
