RE: [APML] Rescan of 2002 Aurora from Cherry Springs
The colors and composition on your rescans are just breathtaking
Jeff. Great job! Having never seen aurora, how much of the
breadth and color do you actually see visually? Can't wait to
see one some day...

Hello all,

the Nikon

they are

the

35 plus did

use the

that I increased

point on the

with
