The
      robotic digital barn door mount was employed once again on the
      night of August 12-13, 2010. 80 exposures, 5 minutes each were
      taken, but the last few hours the battery powering the motor
      drive failed and the last few are trailed. But the last exposure
      has the best of 8 meteors recorded - a brilliant Venus brightness
      object cutting across the top of the frame as the blue glow from
      the approaching twilight was in progress. Here are the results
      of the all night set, with the 17mm f/4.5 lens and ISO800.
 

      
 Here
      is the best meteor of the night, at the top of the frame, about
      -10 magnitude.

      shows all the meteors recorded, with the first object being a
      satellite trail from an Iridium flare. A line profile for each
      meteor is also portrayed.
