We present results of two-hour non-interrupted observations of solargranulation obtained under excellent seeing conditions with the largestaperture ground-based solar telescope - the New Solar Telescope (NST) - of BigBear Solar Observatory. Observations were performed with adaptive opticscorrection using a broad-band TiO filter in the 705.7 nm spectral line with atime cadence of 10 s and a pixel size of 0.0375". Photospheric bright points(BPs) were detected and tracked. We find that the BPs detected in NST imagesare co-spatial with those visible in Hinode/SOT G-band images. In cases whereHinode/SOT detects one large BP, NST detects several separated BPs. Extendedfiligree features are clearly fragmented into separate BPs in NST images. Thedistribution function of BP sizes extends to the diffraction limit of NST (77km) without saturation and corresponds to a log-normal distribution. Thelifetime distribution function follows a log-normal approximation for all BPswith lifetime exceeding 100 s. A majority of BPs are transient eventsreflecting the strong dynamics of the quiet sun: 98.6% of BPs live less than120 s. The longest registered life time was 44 minutes. The size and maximumintensity of BPs were found to be proportional to their life times.
