Canon 7-d, I was going to use an eight stop ND filter (the biggest stopper I have). Mirror up, maybe a 1/3 to a 1/2 stop down. Trying to figure out what my shutter speed would be with a 300mm lens? I figure f-5.6. Am I in trouble of hurting my camera?
First, eye safety: ND filters will not provide the necessary protection for your eyes so DO NOT use your viewfinder -- Live View only!
Camera safety: You say "eight stop ND filter" -- ND filters are typically rated on a logarithmic scale, i.e. 10^N, so a ND 5.0 is 100,000X reduction of visible light (16.6 stops). An 8.0 is huge (26.6 stops), more than what you need, while an "8-stop" ND would be an ND "2.4" -- not nearly enough. Since I don't know what your ND actually achieves, I can't answer your question. But if you have an ND 4.0 or 5.0 (13.3 stops and 16.6 stops respectively), that's what you need (I would use the 5.0). Here is the exposure information for both 4.0 and 5.0: http://www.mreclipse.com/SEphoto/SEphoto.html
And again -- don't use your viewfinder!
And to the OP's comment -- based on what I have seen here and elsewhere, there are going to be a lot of people with fried cameras and sadly, damaged eyes.

Totally agree.

Interesting. My Nikon owner's manual cautions against using live view when pointing the camera at the sun.

You use mirror lock up? How do you burn the shutter curtain?
Mirror and shutter curtain are two different things. There are two operations going on in your camera when you take a photo, the mirror first moves up out of the way, then the shutter curtain opens to expose the film/sensor. Without the proper filter in place, one will burn up the guts of their camera.

Oh what idiots our parents free! READ READ READ! Don't do it! So if you don't care about your camera, I guess your eyes don't matter either!

You sure are! Guess the posts here didn't register in your grey matter, if you haven't been following the dumbass questions and ideas of folks and reading the extremely accurate and important advice from people who "do" know, try reading the archives! If you do as you say, your camera is not covered by any warranty known to mankind and neither are you, "ONLY GIVEN ONCE EYE SIGHT"!

YES! ND filters are no good for eclipse photography!

Sunset is safe because the atmosphere has stripped the UV {and other short wavelengths} from the light; that is why the light is red.Does Sunset photography do the same or is it because of the amplification from the long lenses.

Here is one I shot yesterday to practice for shooting the eclipse, camera is still in great working order. Note 6 or 7 sun spots and light cloud.

I am in agreement with the Canon technician. I do not know if there will be an influx of repairs, it could happen with inexperienced photographers for sure.
Like you I will not shoot the eclipse either. I do not have nor I am interested in having what is needed for the eclipse.
I will be watching the forum for the many pictures I am sure are going to be posted.
