The optical photometric and spectroscopic investigations of the massive and merging galaxy cluster Abell 2319 (A2319) are presented here. RTT150 telescope of TÜBİTAK, Antalya, Türkiye used CCD imaging and spectroscopic observations. In this paper, 110 galaxies were determined in A2319 and defined as the magnitudes of the Bessel B and R filters in each cluster member galaxy. Spectral observations were done of the brightest cluster galaxy (BCG) and six additional brilliant galaxies. We estimated the Luminosity Function (LF) of galaxies for each filter. The resulting LF of cluster galaxies for each filter is well-fitted by the Double Schechter function. The best-fit parameter values derived as the characteristic absolute magnitudes are -21.08 ± 0.03, and -20.84 ± 0.01, -21.43 ± 0.02, and -20.54 ± 0.02, and the slopes at the faint end of the LF were -1.34 ± 0.04 and -1.12 ± 0.03, -1.47 ± 0.05 and -1.18 ± 0.03 for B and R filters, respectively.
