NexGen question
I am DIRECTLY on the path of the upcoming Sunday eclipse. I am going out to
set up my camera the next few days. I sent the wife to the welding store, and they have sold 26,000 # 14 lenses in the last two weeks. I have a NexGen, but it only goes up to 13. Why is that when 14 is common for aluminum or SS? Guess I have to go to the other town to get a 4 x 5 # 14. Should be quite a once in a lifetime opportunity. Been where there was 50% coverage, but without traveling a long way to see it, this will be a nice thing. Steve, Toquerville, Utah, North of St. George. The actual center will be about ten miles north of us. But I do want to try to get some nice pictures by fiddling with the camera ahead of time. Me, again. |

A sheet of white paper taped to the inside, and a piece of aluminum foil with a small hole poked in it as the pinhole. It gives a great image that several people can look at at the same time. Jon |

NexGen question
You should be totally fine, as long as your shade turns on from the
sun. i On 2012-05-18, Steve B wrote: I am DIRECTLY on the path of the upcoming Sunday eclipse. I am going out to set up my camera the next few days.

I have no idea what the NexGen is spec'd for but a recent auto helmet I bought said that it gave 16 level of protection for UV and IR even in the undimmed mode so I would expect it to be OK if maybe a bit bright. |
