Solar Eclipse Photos, Aug 2017 Eclipse

08/22/2017 5:50 PM

I was fortunate to be in a cloud free area in Northern Georgia, during totality for the Aug 21st total solar eclipse. Clouds were all around the area, spoiling the view at some popular locations like Rabun Gap and Brasstown Bald (the highest peak in GA.)

I'd experienced one total eclipse before, on a cruise ship at sea. The experience on land, from a mountaintop, was much more dramatic and awesome than I had expected. As totality approached the brightness of daylight itself became much dimmer and somber. During totality I could see for miles off to the west, where the horizon, clouds, and mountaintops were bathed in light like a too-rapid sunset, with just a thin sliver of yellowish light along the horizon.

At my viewing location, a cloak of darkness enveloped the small group I was in. The only light came from solar-LED driveway markers that came on, and a few lamps inside my friend's mountaintop cabin. The solar corona flared outward from behind the moon, bright against the black disk of the moon, yet too dim to cast a shadow.

I managed to get some photos of the partially eclipsed sun before and after totality, which showed some nice sunspots on the sun's surface. I also got some photos of the inner and outer corona. There are a couple nice prominences visible in the shot of the inner corona.

Here's a photo from near the end of the eclipse. With the moon almost gone.

Here's a view of the inner corona.

This last view showing the full corona is how it looked to my eyes.

I used a Nikon full-frame camera on a newtonian reflector telescope, 760 mm focal length, ISO 400, 1/640th sec exposure. During the partial phase I used a solar filter mounted on the front of the telescope.

Most excellent photographs!

And this sentence, "The solar corona flared outward from behind the moon, bright against the black disk of the moon, yet too dim to cast a shadow." sounds like something from a prize winning novel.

Never to be confused with, "It was a dark and stormy night".

Were you able to catch the diamond ring? Which is almost as good as the total eclipse.

Not sure. The transition from partial to total was very fast. I was snapping photos rapidly. Haven't processed most of them yet.

From where my wife and I were (Fox, OR), the corona looked much as in your third photo, but more uniform/symmetrical. I think we wound up very close to the center of the path of totality, and we had good viewing conditions with just a bit of haze. The "diamond ring" effect just as the sun became exposed again was superlative.

Yes, very excellent photography work by a clear professional.

I appreciate those very much, as one can even see sun spots on the solar disc.

Great job well done.

Well done. Thanks. We had broken clouds here in Maryland so our partial total eclipse was touch and go. Still had some nice views with welding lenses. Next time . . .

An 'ok' shot of the 'Diamond Rind'.

Totality shot with a different camera.

Totality -- moments away.

An OK shot?

It's a big diamond and a great shot! Well worth the effort at your end and the wait at mine /ours!

I'm with JE the photos are brilliant. Also on google images it stands up very well.

I think I know why you are a little disappointed as a fraction of a second earlier slims the diamond and there can be amazing effects but that's like trying to catch the moment of impact of bat on ball!

Yes, just a fraction of a second sooner and the shot would have been 'perfect'. I'm still thrilled I got the shots I did.

Beautiful! We had cloud cover here in Sonoma County.

Here in Hemet California we had a 62% of totality. We had clear skies. What I observed was that at 08:15 the temperature was about 86* . At 09:10 , the temperature had dropped almost 12*, then at 09:30 the temperature had risen to about 94*.
