and this is probably why
300 f/4 screwdrive AF
Kiron 2x TC
2 6 stop B+W ND filters stacked.
Induro AT413 legs
Arca Swiss Z1
12 stops of ND is not quite enough, but when using Nikon lenses on the Sony, the aperture stays stopped down, further cutting the light. And there's no optical viewfinder, so it can't damage your eyes. There's going to be a transit of Mercury in 2016. But Mercury is so small you probably won't be able to tell it from a sunspot. The transit of Venus last year was awesome. I got a couple of good pics. But there won't be another Venus transit until 2117-glad it wasn't cloudy here and I got to see it.
