Green Flash Sequence from Marathon Key15 viewsWe watch for it 6 times and saw it 3 times.
Canon Rebel XTi 55-200mm zoom with polarizers
(the polarizers were not needed I just didn't bother to take it off.
Set at 200mm f/5.6, iso200, 1/640 sec.
The "green flash" occurs because the atmosphere strongly refracts lights of objects low on the horizon, just like a prism. With red on the bottom and blue on the top.Jun 05, 2010

Focus was soft. The seeing was poor and the tracking was problamatic, had to use 5sec integrations and that's a little too long for my setup. All the subs had a little trailing and could not use 4 of them.
