[QUOTE="Binastro, post: 3175234, member: 111403"] . Today's Independent newspaper has an article on the solar eclipse on March 20. It is a rather strange and rather brief article. It mentions that one has to take care using a camera. This would be correct if you are using an optical viewfinder and a long focus lens. What is really strange is the following and I quote ' energy groups have voiced concerns about the power supply, given so much of it is now made up of solar energy. They have worked to head it off-but concerns remain that systems could see problems as people head into work and the power providers deal with the eclipse.' This seems very strange indeed to me, what do they do when it is cloudy? The article mentions that you need a solar filter to view the eclipse, and says that they will be available. But I think that this eclipse covers territory where 2 billion people live. If even 200 million tried to view it, I don't think that there are going to be, say, 100 million safe eclipse glasses available. I quote again ' you might remember the warnings from 1999: never look straight into the Sun. If you do, you can permanently damage the back of your eye (it should say eyes) -where there are no pain sensors, so you won't even know that anything's gone wrong.' ' The key thing is to get some kind of dimming lens to watch the eclipse though. These will probably be readily available ahead of the event.' (I think that the first sentence here may give people the false impression to look through any piece of dark material, with inevitable multiple cases of eye injury). I imagine, that governments will get into the act late and probably as in previous times be at a loss to advise properly. [/QUOTE]
