Eclipse - glass roof + polarized shades?

[hariclt]

So the proper eclipse viewing shades are sold out all over town and I figured just using the all glass roof - plus some good polarized sunglasses would be enough protection? Thoughts?

Thx

You will need more then that. Still to bright to view the sun directly. I tested.

To make it work, I added 6ND filter paper X2 layers plus polarized glasses. Works on X (top of windshield) and S all glass roof.

Short road to permanent blindness. #14 or darker welding filter, ISO certified glasses or a pinhole camera. (Pinhole camera is easy--look it up.)

Thanks for the response - did you do something scientific or just eyeballed it?

Just edited my post above to include what worked.

Thank you! That's an excellent design. I just made my own, fashioned after that!

You can just use a pasta strainer it will make dozens of pinholes or even better, watch the eclipse in a forest, the leaves on the trees will create thousands of pinholes. It is a magical experience. Most people look for an open meadow to see the eclipse, but a forested area is better.

ABSOLUTELY NOT. Seriously. Do not do that.
