Alternative light filter

Yesterday, when a gap was formed among the gloomy Moscow sky through which the eclipsing Sun peeped, I decided to admire it no matter what.
Since my eyes will still come in handy, the question arose of what, in fact, to observe this overly bright astronomical phenomenon.

Very appropriately, an X-ray of a cat's paw, which fell from the balcony a few days ago, came to hand.
Everything was very clearly visible. :) Even the photo turned out.

Recommend. :)
