Annular Eclipse May 20,2012

...Most welding glass out there seems to be shade #5-8. So, be careful if using welding glass.

I am a complete novice about this, so I am being conservative. But it also seems to be about more than just number of stops and that you have to be very careful about blocking non-visible light, both IR and UV.

See link below. Welding glass in shades of 10-15. I am not an expert,but it sounds like welding glass in the range you are looking for is avaialble.

I saw what was called welding safety glasses that were shades of 5-8, but I do not think those would ever be considered good enough for arc welding.

Yep, and yet welding safety googles with #5 shade glass pop up twice in the first four options if you type in "solar eclipse glasses" on amazon. For welding glass, I've only seen the #14 recommended. I've read about people successfully using shades ~11-12, and I may try shade 12 with the 7D in Live view. But for direct viewing, I am going to stay with the baader film I bought.

These are some summaries as I have found on the web:
