I thought of this too late but it would have been cool to have these if you were under the total eclipse. Bring them out when totality starts and see if they change!
I was just browsing astronomy sites, and came across yours. I thought the UV-C range you quoted seemed a bit large, and doing searches it looks like it starts around 180/200 nm.
Good catch. I got this one wrong. My source has it listed as 1nm through 280nm, but other sources start at 100nm. The good news is that UV-C is stopped by the ozone layer and isn't a factor here.
True, but eclipse glasses can be used any day of the year. The ISO 12312-2 standards are for solar viewing in general. All that aside, I republished this video because the original had some issues. I apologize for any repetitiveness.
I’m not sure that you can see much on the sun with just glasses. Even with a telescope sunspots are pretty small. I would be interested to see if you can actually see anything more than the disk? I’m from the northwest of the UK. We seldom see the sun…
You are correct. It does look pretty small. The previous version of this video contained a bad typo an some confusing parts - that was the main driver for this updated version.
I like your methodology.

That would've been a great idea! I was so mesmerized by totality that I forgot about a lot, so I probably would've forgotten to try the beads, lol.
good job!

I have never trusted those dime store glasses. I didn't in 2017, and I still don't. Give me my Thousand Oaks Solar filter any day of the week.
Neat info.
In breaking news: you’ve missed the eclipse.

I used welders glass worked fine for me and the guy I bought it from said it is safe to use, what are your thoughts?
Unfortunately, I don't know.
