Perseid Meteor Shower at Trillium Lake Friday morning, August 13, 2010.
I took 360, 30 second exposures to get this one shot. This is an aggregate of the meteors that fell in three hours last night.
Exposure - 30 seconds x 360 exposures
Aperture - f/2.8
Focal Length - 11 mm
ISO Speed - 2000
Basically - This shot was created by taking 360 exposures and then taking the shots that had meteor's in them out and layering them over each other and masking and merging them into the lower layer. I did each layer one at a time.
This shot did not take into consideration the rotation of Earth during the three hours that I was shooting, thus the lack of a common point of origin. I have since compensated using a time/rotation adjustment and recompiled the layers into this image HERE.
