Northern Lights

[wxnut]

I shoot northern lights for about 30 seconds when there is no other lights around. the pics with the churches are for 6 seconds. At 30 seconds, they are about 3 times brighter than what we see with the eye.

My brother was shooting that night as well, but at shorter exposure times. This is about 1.5 to 2 times brighter than what they were.
