The solar eclipse in exactly two weeks. In preparing for it though, I've become amazed at the sheer recklessness people have shown in capitalizing on it. Ordinary people for example are renting their driveways for hundreds of dollars, weather anchors are claiming you can see the solar eclipse through the clouds to escape having to give overcast warnings, and I just bought solar eclipse glasses which I recently learned ignored a fatal manufacturing error that makes them 100% unusable. So I've felt forced to go full DIY.
I'm going to be pissed if this is how things are when Betelgeuse explodes, or I'm going to be exploding too.
Anything with an ISO-approved number 14 lens will do the job, so might a surface with enough reflectivity to reflect the light but nothing else (think those homemade viewing kits people make out of kleenex boxes), or you can watch it through a rear view camera, the last one being considered most beneficial.
