Essentially, it's the ultimate photo challenge. On April 8th, photographers across the continental United States – and especially photographers within the band of totality stretching from Texas to Maine – will have no more than a few minutes to get the shot of a lifetime when the moon passes in front of the sun, and a large swath of North America will be treated to a total eclipse.

And if you ask anybody who knows anything about astronomy, it is a huge deal. Dr. Tyler Nordgren is such a man. He's a professor of physics and astronomy, an award-winning photographer and a self-described Night Sky Ambassador. Here's what he had to say about the solar eclipse of August 21, 2017:

"Half the people that are alive right now weren’t even alive the last time something like this was visible from the continental US. Secondly, there are 12 million people just living in the path of totality that are going to get the chance to see it, so it will be the most-viewed total solar eclipse probably in history. The most seen, most photographed, most shared, most tweeted – potentially the most people in total are going to be able to experience this in one form or another. "

"See your first eclipse, photograph your second. "

But unless you're a seasoned landscape photographer or astrophotographer, Dr. Nordgren thinks you might be better off not photographing it at all and just enjoying the view. He quotes Warren De la Rue, a pioneer of astrophotography, and the first person to photograph a total eclipse. "He wrote in his journal afterwards, that if he ever got the chance to see another one, he hoped to be able to see it without any equipment at all. "

In short, "See your first eclipse, photograph your second. " But if you're unconvinced, Dr. Nordgren does have some advice.

How to prepare to photograph the eclipse

Preparation is key. Time is of the essence. Of course, you'll want a tripod and a cable release to lock everything down and minimize shake.

"If you really must photograph this, you’re going to want to practice a whole bunch of techniques in the weeks leading up so it’s as second nature as absolutely possible during those precious seconds. "

Don't forget to take off the filter during totality!

Protecting your eyesight and your gear is equally important. It's only safe to point your eyes or your camera sensor directly at the sun during totality. Just seconds before or after and you're risking serious damage. He suggests a pair of solar eclipse glasses and a filter for your lens. Per NASA, your glasses should meet the ISO 12312-2 international standard.

Be sure to use both during partial phases of the eclipse – you risk damaging your eyesight, not to mention your camera, with just a pair of glasses and an unfiltered lens. Crucially, don't forget to take off the filter during totality. You'll be extremely disappointed with the results if you don't.

For nitty gritty details, Lensrentals posted a useful article detailing some specific settings to dial in if you plan on using a longer lens.

What lens to use to photograph the eclipse

What kind of lens should you use? Well, not surprisingly, it all depends on what you're going for. If you want the sun as your main subject, you'll obviously want a longer lens. "To really capture big detail in the corona and the object itself, you'll want a lens with a focal length of around 500mm; between 400 and 600mm at least. "

But don't forget that a total eclipse also presents a unique landscape photo opportunity. If you'd rather capture the eerie effect on the scene, a wider lens will produce excellent results too. It's all a matter of personal preference.

No matter what kind of shot you're going for, you can size things up ahead of time by photographing a full moon.

"Something to keep in mind is that during totality the sun turns black, and is surrounded by this ghostly corona, so the spectacle of the object itself is this black disk with this white glow around it. That black disk is the size of the full moon, so take whatever your camera equipment is, take whatever your lens is and go out and photograph the next full moon. See if whatever size dot that appears. If that’s interesting to you, then great – that’s the lens to use. "

Should you go to the path of the totality?

In a word: yes.

If you're set on photographing the eclipse and have the safety and gear requirements nailed down, all that's left to do is get yourself into the path of totality for the big moment. Easy enough, right? Well, unless you're lucky enough to live there, or you started planning your eclipse vacation years ago, chances are only getting slimmer that you'll be able to find accommodations. Your best bet is to find what you can within a reasonable driving distance and set out as early as possible.

Ideally, you also want to aim for somewhere that's less likely to have cloud cover. Dr. Nordgren knows all too well what a cloudy eclipse view looks like.

"If you’re going to do the close-up photograph, you could be almost anywhere provided you’ve got clear skies. But I’ve also seen some really spectacular photos of totality through wispy clouds that give this dramatic view as well. . . just as long as you’re within that path of totality and the cloud cover is not so total that you’re utterly blacked out. And I’ve had that happen. "

This is the partial phase just a minute or two before totality in the Faroe Islands. Those clouds totally socked us all in 30 seconds before totality so we saw nothing.

If you're hoping to get a wider shot, then great news: this eclipse will cross much of the continental US. Provided you can get there, you can pretty much take your pick of landscapes. "What do you find compelling?"

Whether or not you can get to the path of totality, and whether or not you choose to photograph the event, you'll still be treated to an amazing array of photos and videos from photographers across the US. And unless you're dead set on photographing it, consider leaving the camera at home.

"If you haven’t seen a total solar eclipse, I encourage you, don’t waste your time photographing it. "

"If you haven’t seen a total solar eclipse, I encourage you, don’t waste your time photographing it. Chances are, somebody else will get a better photo. But if you are that kind of expert photographer, practice so that you can set your camera up and let it do its thing with as little input as possible. " In the very best case scenario, you'll get a couple of minutes.

"That is not a lot of time to see what I think is the most awe-inspiring, unnatural, natural experience in nature. "
