Pegasus Cluster (ペガサス星団) Messier 15

It was a thinly cloudy and  moon with 100% brightness, but since it was my first chance to take photos in three days, I aimed for the globular cluster.
Only 25% of the stars in the first frame were visible in the other frames.
I wonder if this object was helped by the beautiful bright stars around it.
