Images were captured beginning at 827 pm and ending at 1106 pm.

Note the track of the airplane on approach to Barnstable Municipal Airport Runway 33 at 951 pm, which was captured in image #75 of a sequence of 143 30 second exposures each separated by 4 seconds (probably too long a separation) for the camera to recycle.

Also note the slight oval movement of everything around Polaris, including Polaris itself, due to its slight offset from true north.
