Solar Eclipse question

Postby supergirl » Wed Mar 18, 2015 11:45 am

Hello

I hope someone can help me!

I cant put my hand on the special glasses. I found a glass welder filter grade 11. Does anyone know if it is sufficient?
I cant find the answer on google.

Of course i can always build a pinhole shoebox but i am pursuing this avenue first.

Many thanks for your help. Supergirl

BBC's Sky at Night magazine was giving them free (£5 for magazine) - but of course may well have sold out by now.

I thought I read somewhere that the welder glasses should be grade 12 and above.
