  1. “You can watch the sun directly with a telescope, but only twice.”

    “Once with each eye.”

  2. What if you took a photo of the lens with a super low exposure, would you get a really cool photo of the sun or just a bright spot?

  3. Why didn’t Trump do this with a telescope when he was in office? I mean he didn’t believe in science.

  4. Pardon my ignorance, but my brain is thinking there’s a chance for energy production here, with magnification I think. I’ve not yet studied solar power, but perhaps that’s what’s used? Idk my brain is misfiring, but trying.

  5. Have heard there’s a kind of camera filter to reduce the brightness of sun to prevent people from looking at the telescope directly

  6. Pirates actually often had eye patches from using a sextant and the sun to navigate, and burning out their eyes.

  7. I once pointed my telescope at the sun and put some eclipse glasses on to look at it. I got a good look for about 10 seconds before the sun burned a hole through my glasses and pierced my naked eyeball with it’s concentrated agony.
    Would do again 10/10

  8. Impressed that the secondary mirror held up. That’s a lot of energy concentrated in a small piece of glass and aluminum.

  9. Don’t some sun telescopes have a 99% or 99.9% attenuation filter? Does it allow you to view the sun with the naked eye? Or is it still dangerous?

  10. Also if you place the dark film over the eye lense, instead of over the telescope opening, it will be a bad day.

  11. But really, it’s the UV light. This demo is misleading and dangerous because even if you dim the light enough that it doesn’t hurt, if you’re not blocking the UV, you’ll still go blind.

    Bright lights hurt your eyes in the sense that your pain receptors fire. But UV hurts your eyes in the sense that they’re damaged. Removing pain by reducing brightness doesn’t remove damage from UV.

  12. Also, DON’T LOOK AT THE FOCUSED LIGHT EITHER. IT’S STRONG ENOUGH TO BURN WOOD AND IT’LL DAMAGE YOUR EYES.

  13. I forgot the eyepiece cap on my telescope and had it toward at the sun for viewing. All of a sudden my house is full of smoke and I had an eyepiece cap with a hole melted into it. I’m lucky ny telescope wasn’t damaged and I had no lenses to clean. I learned something that day lol.

  14. **SHITTY LIFE PRO TIP:**

    Have vision problems?

    *Stare into a telecope.*

    ##It’s free LASIK!
