The author was being optimistic in reckoning total eclipses at any point as “once in a lifetime.” I think that Jan Meesus gives the average interval between totality for a point on earth as about 325 years. (It’s a difficult calculation.) However, occasionally some places have two eclipses less than 18 monthes apart. The last total eclipse in New York City was in 1925, for instance.

It’s provocative that Nova Scotia had two eclipses in the early 1970’s either of which was before Carly Simon’s “Your so vain.?

Considering the length of time a total eclipse lasts, it's an amazing thing to see!

Diamond Ring Effect During 1979 Eclipse (79SE2-4)

The last rays of sunlight shine through deep lunar valleys as the solar corona leaps into view. This eclipse was also noteworthy for the brilliant red solar prominences visible around the Moon's limb.

Yes, liked the background music too. Definitely went with the video.

During totality it is safe to look directly at the sun--when it's totally hidden. That's what I was told in 1999 when I was fortunate to see the total eclipse that was visible in Europe.

The next one which will be visible in the US will be on August 21, 2017, passing from Oregon to South Carolina, followed by one on April 8, 2024, passing from Texas up to Maine.

There is one total eclipse this year, on July 22, a very long one (6 minutes 39 seconds of totality at the best locations), but it will be visible only in parts of Asia and the Pacific.

I read once that on average a particular spot is in the path of a total eclipse once every 360 years.

You'll have to wait until 2017 for the next total eclipse.

Totality will occur somewheres around the Land Between the Lake, Kentucky.

Noonish. So bring me a ham sandwich, will ya.

Here's one for you ...

Sit about 1 meter from your screen and hold up your thumb halfway between you and it, look at your thumb, then focus on the image you see just behind it (you can move your thumb forward and back till this occurs), remove thumb.

You should hopefully have combined the two images into a single 3D one.

That’s pretty neat! Thanks for posting. I knew you could get a 3D image like that but had not heard the tip about using your thumb to set it up.

I am a professional freelance photographer, starving artist in my wife’s language. I went through a phase a couple of years ago where I was enamored with stereo pictures. I have an adapter for my Nikon cameras that lets me take stereo pairs. What a blast. Never could figure out how to make money with it, but that’s hardly unique to my career.

I am going to download your moon image and use it to make some similar images from my own pictures. If I have any luck I’ll post a couple for you to try out. I went through a real phase of looking for things to really take advantage of the 3D effect. But then I passed out of that phase, into another similarly titillating but unprofitable phase. This time it was large format printing. I love making posters and have even managed to sell a few.

Thanks for the post! At least this time I’ll be dabbling in something that won’t cost me a fortune since I already have the equipment!

There is a fascinating and very well made documentary, "The Privileged Plant" that goes into great detail about how unique Earth is not only to have life, but even more to let its inhabitants explore the rest of universe. I would would heartily recommend both the video and the book! Here's a link to the info about it:

The Privileged Planet

There's a link there to view a sample of the video. I didn't check it out, but it's probably worth the effort.

My FIL was a great hobby photographer....and he loved 3D. I recall he had a special camera and viewer for all his shots. It was cumbersome and frankly a pain-in-the-neck to view...but we humored him with all sorts of OOOOOOOOOOOOOOs and AAAAAAAAAHHHHHHHs.

I’d be interested in your results!

Look’s great ....I’ll add it to my list. The video was a good tease. I’m such a Brian Greene fan, that I know I’ll enjoy it!

Thank you!

Such an odd coincidence I think.

It reminded me more of the One Ring or of The Eye of Sauron.

Cheers!

“it is all thanks to a striking coincidence.”

It wasn't always so and will cease to be so in the future.

Even more interesting. Almost like a celestial alarm clock!
