Going to be watching the Great American Eclipse on Monday, but

Just stare at it like everyone else will. Scientist just tell you not to because they're cowards who spend most of their time in dimly lit rooms with mice (which are also cowards).

Ut's only bad if you stare at it for longer than a day.

During the actual total eclipse it is safe to take off your filter, according to NASA. Just not while it is only partially covered. But yeah I mean... I've looked at the sun before. Not blind yet.

Get a piece of clear glass, then 'burn' it with a lighter so it's all black. You can look through the blackened glass at the eclipse safely.

>>61982771
Just black the sun with your phone, open the camera and watch it through the screen.

Use a binocular and a tripod (or be creative with the stand). Damage from UV can be subtle, and why the fuck would you gamble your eyes to view something as inconsequential as an eclipse?

Just get some welding goggles nigga

>>61982771
Look through an unprinted CD or DVD. Preferably a recordable as the aubstrate is thicker.

just poke a hole with a sharp pencil in a piece of paper and look through the hole dumbass

Holy shit this is brilliant.

This.

OP the problem isn't just UVA/B, it's basic visible light intensity. If you're looking directly at the full eclipse while it's ending, your eyes don't have time to adjust to the sudden spike in intensity. This kills the eyes.

most welding goggles aren't safe for this either

>>61982771
Chip packet will work (make sure it's not scratched), welding glass too if it's the right grade.

>>61984495
Yes they are jackass, especially electrode ones

>According to the NASA total eclipse website, a shade 14 welding lens is the only lens adequate for viewing the eclipse.
>Holston Gasses Vice President Phil Kirby said the lens most commonly selected for welding is a shade 10 or 11.
>"We stock from a 9 to a 13 lens (and) usually don't stock a 14 unless ordered," he said.

Use binoculars, they make the image bigger which spreads the power of the sun over a larger part of your eye, decreasing the power per area and keeping your eyes safe. Look for binoculars with big lenses at the front.

This is the preferred method used by top scientists.

Also got dubs of truth twice in a row.

Even less chance of eye damage if you use a telescope.

Welding goggles are rated with a 'Shade' number. Higher number blocks more light.
You need at least Shade 12.

Most common goggles are Shade 5

>>61985431
That's why he said electrode ones. 10-13 is mostly stocked because that's all that's needed for torch welding.

>>61985579
and that's why i said "most", not "all".

>>61982771
Retarded astronomy thread?
I partially melted some welder's goggles by using my telescope to look at the sun. Could've fucked my telescope too.

>>61985659
You probably looked at the sun at sunset or sunrise. Because the sun is larger at these times it can cause damage. At noon, the sun is at its smallest and therefore safe to observe.

This
When did the world forget this is how to stare at the sun

When I was a kid, I lived in a house that had a screen door on the back. On sunny summer/autumn evenings, light from the setting sun would shine through a tiny pinhole in the seal of the screendoor, and cast a perfect image of the sunset on the wall, upside down.

Nice
Would make a cool album cover

Where is it so I could see it

Don't do this, this makes mustard gas.

>>61982771
Go to hardware store and get welding mask.
