To those that are going to be viewing the Eclipse on the 21st (Tomorrow as of this post) I have some important infoz

MAKE SURE ANY SHADES YOU USE MEET REQUIREMENT ISO 12312-2:2015
AND EN 1836:2005 AND QUEENSLAND DIRECTIVE AS/NZS 1338.1:1992

One or more should be listed on the inner side of the glasses, shades should be nigh-opaque with only extremely bright light visible when put on.

If you do not have a pair, don't panic. Here are some tutorials on how to make a pinhole projector:

(I made one of these to look at the transit of Venus a few years back, they are awesome)

This will be converted/replaced by a "did you see the eclipse/what did you think" thread after it's over

Somewhat surreal, too. The lights went out like God turned down a dimmer switch, and then you're looking at this giant glowing hole in the sky. A couple planets were visible too. Not too many stars since we were in a fairly well-populated area and there were lots of city lights around us. It was more of a very dim twilight than full darkness.
