RE: Aurora Borealis Photos



As a follow-up to my earlier posting, here is a composite photo (taken last
nite) of what the same sky looks like without the aurora being present. This
composite has 141 frames in it, with each frame being a 90 second exposure.
The total span is 3 hrs 45 min, with a gap due to the camera's battery
running out of juice.

This composite can be compared with the composites in the last 2 frames of
