I’ve seen a couple of partial eclipses, and they were cool, but experiencing a total eclipse / totality was truly something spectacular. It was even worth the 5 hour drive to get home. The morning of the 21st we were driving up and down 385/26 between Greenville and Newberry, trying to get out of the clouds. We finally ran out of time and had to get started, and we ended up in the McDonalds parking lot in Fountain Inn, SC.
I used the Tamron 150-600mm G2 @ 550mm (appears to get noticeably soft at 600) + the Tamron 2x teleconverter for it. At that point we’re at F13 and I stopped down to F14. This was attached to the Canon 5Ds. As this was perhaps a once in a lifetime opportunity, I took the HDR / bracketing spray and pray approach to make sure I gathered enough (7 shot, 12 stop spread, 2 stop increments). It’s an extremely sensitive focal length and resolution, so all the stabilization techniques were of course applied. At this focal length, the moon moves very fast, but Photomatix simply wasn’t aligning them. I ended up aligning the manually, before handing them off to Photomatix.
