An extensive photometric study of the cluster to determine the cluster reddening, distance, age and metallicity has been done among stars of magnitude ≤ 18 (bright stars). Stars of magnitude > 18 (faint stars) were left out hence creating a gap in the membership of NGC 6811 (Curtis et al. 2019). Thus the problem addressed was that the number of known faint binary stars with δ scuti component in open cluster NGC 6811 are still few. This study has made a contribution to the number of known faint δ scuti stars in this cluster using Kepler and Gaia’s second data Release (DR2).
