Note it appears the black polymer Baader film might not be suitable for
eyes-only eclipse viewing too.
LOL! I remember back in the old days, use to hold a piece of glass over a
candle to cover it with soot than use it to view the eclipse.
After 40 years, I still have 20/20 vision!
For the first solar eclipse I can remember my teacher gave every pupil a
piece of blotting paper with a needle hole in it. We watched the eclipse
through the hole.
For the next eclipse the teacher (not the same one) gave us all folded
black and white film negatives.
I bet , was not certified by OSA, CE, government and CIA and still worked? (o:
