When I went to see a total eclipse I was surprised that even a tiny slit of the sun was still hard to look at. Not sure why anyone would try to stare at that.

- dekhn 3y agogalileo (the galileo) used to stare at the sun for extended periods of time (without a telescope), to the point he could identify sunspots. But IIUC he looked at it near the horizon when it's attenuated by more atmosphere.
