Lee, Paul, Yes, the photo has been doctored to give far more detail than you would actually see in those conditions.Here is a photo I took at White Dome during a much dimmer aurora.Even with the longer exposure everything is still in silhouette. The doctored photo is very impressive, but does not reflect reality. Grover Schrayer -------------- next part -------------- A non-text attachment was scrubbed...
