Kat Marsden:

This is what just a *couple seconds *of magnified sunlight did to the inside of one of my telescope lenses.
这就是我的望远镜镜头内部仅仅被放大了的太阳光照射“几秒钟”所照射带来的结果。

I pointed my telescope at the sun without a filter, then put the solar filter on the end of my telescope only moments later. This happened to the hard plastic of the inner lens after less than four seconds of exposed sunlight. Imagine your eye on the receiving end of that!
在不使用滤光镜的情况下我拿望远镜直接对准太阳，随后马上把滤光镜又装回去。这就是望远镜内部的塑料被太阳光直接照射了四秒钟的结果。想想一下如果这是你的眼睛会发生什么！
