Compilation of Pereseid fireballs captured in a series of 15s exposures using 4.5 mm fisheye lens on Canon T3i on August 5/6, 7/8, 8/9, 9/10, 11/12 and 13/14 from Wingate Campsite in Dead Point Horse State Park, Utah. Sporadic fireball happened on Aug. 10th around 4:48am MDT (other sporadic meteors were excluded). Fisheye all-sky pictures were transformed into polar coordinate projections using Iris software, star background was aligned and fireballs merged with sky background using maximum intensity projection in ImageJ.
