Will the total solar eclipse of 21 August 2017, which will transit across the continental USA, live up to the hype? The eclipse will also be visible as a partial eclipse from pretty much all of Canada and Mexico.
I've already seen that some writers are expecting the eclipse to be the most-photographed event in history (at least far). I'm planning on seeing the eclipse first hand, as are many other astronomy fans and photographers. My contacts near our planned main observing site are worrying about the traffic. Stores specializing in astronomy gear are selling out of excise viewers.
Whether or not the event – compounded by human interest – lives up to it all depends on the weather too. Right now I'm hopeful it will cooperate. Long-range forecasts (always to be taken with a grain of salt) show a sunny day expected on the 21st at my planned observing site. Just in case, though, I do have a backup site thanks to the suggestions of friends in the area.
In the mean time, many people planning on attending the eclipse in its totality are practicing their photographic methods. I've been preparing by running a series of tests of interval exposures with wide-angle lenses. Shot through solar filters, these photos are then stacked together to create a single image showing the track of the sun through the sky.
Above, a Nikon D800 dSLR on a sturdy tripod with a wide angle lens and a solar filter, set up to take photos every 30 seconds. The sun moves through the sky at a rate of about 15 degrees per hour. At a diameter of about 30 arc-minutes this means that the sun shifts by its own diameter every two minutes.
I've also been running through other equipment options, such as whether I should try to set up a telescope and motorized mount to follow the sun. Given the travel distance and the practicalities of carting around heavy gear, I'm now planning to minimize the kit and maximize the experience, but also be equipped to take some interesting snaps.
On to more mundane things today though, like having a plumber over this morning to replace some old plastic water lines that are now prone to leak.
