I don't recall the actual amount she was charging, but it was substantial.

These maps of Nebraska and Wyoming show the path of totality for the 2017 eclipse and the times when the sun will be 100 percent eclipsed in each region.

"And then once the moon completely covers the sun, all of a sudden revealed to us is this outer atmosphere of the sun called the corona, which is this silky, ethereal structure", Young says. The solar eclipse of the moon is said to obscure maybe as much as 76 percent of the sun's rays.

"'It's so risky for people to look at the sun even for brief periods of time because you can cause permanent damage to the retina", he says.

No one wants that, so here's what you gotta do.

Even though Canyon County will witness a 99.5 percent eclipse, experts argue the spectacle in totality is worth the trip.

"This is a really awesome chance to just open the public's eyes to wonder", says Montana State University's Angela Des Jardins, a physicist in charge of a NASA eclipse ballooning project. The sun will reach its maximum coverage about 1:20 p.m. and stay that way for nearly three minutes.

Leave early. The partial phase of the eclipse will happen late in the 11 a.m. hour, with totality at about 1:15 p.m., and the final partial phase ending at about 2:45.

Millions of Americans are getting ready to view the next eclipse on august 21, but Dr. Russell van Gelder from the University of Washington School of Medicine warns blindness is a risk if you don't have proper eye protection. Because there are no pain receptors in the retina, damage can occur without any sensation of pain.

The Toshiba Vision screen in New York's Times Square will broadcast the program live in its entirety to give the public a big-screen view of the eclipse. "That's the one thing that I'm most nervous about and I know most eclipse chasers are most nervous about", Young says. Just keep in mind to wear safety glasses.

A mother, who has a misguided view of how nature works, asked if it was possible to reschedule the total solar eclipse because the date wasn't practical for her.

Totality: It's safe to take your glasses off now and look up. You will need special eclipse or solar viewers to look at the sun safely.

"The real glasses look very similar to movie theater 3-D glasses and can be purchased for as little as $2", said Steve Bernas, president and CEO of Better Business Bureau of Chicago and Northern Illinois.

And finally, try your local library for eclipse viewing parties.

Finally, if you can't find glasses anywhere (they are selling out at stores in hours), Young said welding glasses can work in a pinch.

Will I be able to see it?

"Therefore, the city believes that it is in the best interest and safety of residents, visitors, and citizens to prohibit tour vehicles, including horse carriages, small tour busses, etc. from operating on the peninsula on August 21, 2017, to help alleviate and assist with traffic congestion", as stated in the Department of Livability and Tourism's request to the Traffic and Transportation Committee. The entire North American continent will see at least a partial eclipse, which is expected to result in temperature drops up to 20 degrees and an uptick in wind, according to NASA.

"But you've got to be careful", says optometrist Myron Wasiuta.

Be sure you know the capabilities of your camera before Eclipse Day. Stars also can appear.

How rare is a total solar eclipse?

One alternative method of experiencing the eclipse is to use a pinhole projector.
