Thank you Jon.
I did find a multi coated UV Filter for my camera. I also have the glasses.

I am going to do some more research on it to see if there is anything else I can do.

If you come up with any ideas, please let me know. I'm not taking any chances with my eyes or my equipment.

Have a great day.

Turn on your damn TV. Or login to any number of websites.
You'll find eclipse pictures better than you can take.
And you won't blow out your eyes setting up your camera.

I can't understand why people who are concerned about damaging
their camera are willing to risk their eyesight on possibly
the most risky situation they'll ever encounter.

Are two minutes of, "ok that's dark" worth risking a lifetime
of, "everything's dark?"

Stay home and turn on your TV.


I don't have a TV and the photos I take will have MY copyright on them
with no restrictions on how I use them.

This shows the unfortunate part of the pervasiveness of the net. Such
over-wrought posts get distributed wildly.

During the last total eclipse - 1978 or thereabouts - there was none
of this kind of hysteria. The instructions were simple: Don't look
directly at the sun without protection. Don't rely on sun glasses.
Welding filters or fully exposed B&W film are adequately dense. Don't
look at the sun with any magnification regardless of the presence of
outlet filters. No mass casualties afterward.

Misty:

Your UV filter will do nothing to attenuate the brightness of the sun
in the visible spectrum. It's probably too late now to get them but
welding filters are wonderful. I fabricated a bracket to hold a stack
of them in front of my camera lens. I use a stack of filters, both to
fine-tune the density and to still have protection if one failed.

With the old glass filters, there was a risk of cracking from the
heat. Most (all?) filters are now made of plastic which won't crack.
If the front one were to start melting, I would notice that as the
image on my camera start to brighten.

I have tested my setup extensively with the clear-sky sun and it works
perfectly.

If you have a point and shoot camera, a filter out of the cheap
viewing glasses (ISO, UL and ANSI approval vital to separate out the
fakes) can be held in front of your lens. My viewing glasses are a
little dark for good photography but if you put your camera on a
tripod so you can use a slow shutter speed, it should work well
enough.
