Partial Solar Eclipse

There's been mounting excitement about the eclipse over the past few days – 'would the skies be clear?'; 'how to view it safely', but not much mention of how you might go about trying to photograph it.

There is really only one photographic tool that can be used and that is what's called a 10-stop Neutral Density filter. This looks like a completely black piece of glass, not unlike welder's goggles, and it reduces the light passing through it by 1000 times. That's a lot of light blockage!

Another technical challenge is accurate focus. Autofocus will simply not work well on such a bright object, so using manual focus with Live View to check accuracy is the only sure way to get a sharp image of the outline of the sun and moon as the pass each other.

Fortunately the heavy cloud of early morning did thin somewhat - just enough to witness a rare celestial event.
