Tomorrow an annular eclipse will start in Canada and end in a remote part of Russia. People in areas of the United States will see a partial eclipse. I will be viewing the vent as it oeaks just after sunrise over Lake Ontario.
I understand that one must protect the camera sensor from the harmful rays of the sun. Do people generally use ND filters?
I have 6x and 10x Lee filters for my EOS R.
Any preference for one over the other? Or are specialized solar eclipse filters required?

I kept the filter from the last eclipse. However, if the sun is low on the horizon there is enough haze to avoid the need for a filter, the same as shooting a sunrise or sunset.
These are from an eclipse 20 May 2012

From the web:

"A solar filter must be used on the lens throughout the partial phases for both photography and safe viewing. These filters typically attenuate the sun's visible and infrared energy by a factor of 100,000."

For example, a commercially offered filter is Hoya Pro ND100000 77mm Solar Filter

Jack,

It looks to me like you may have blown your highlights there . :-P

As long as the eclipse is low on the horizon, or partially obscured by clouds, he can get by without a filter. Even Amazon won't deliver by tomorrow AM.
Here's the transit of Venus at sunset from June 2012. No filter. If the sun rises more than about 3 diameters above the horizon, a filter is needed. A thin layer of clouds will be helpful.

As this eclipse will be very advanced at sunrise, he can get good shots if the horizon is clear.

Without a filter, it is foolish to get the entire eclipse seen after sunrise, but some nice images are possible before the sun gets too bright.

:-P I think that was my first eclipse, so I was still learning. It reminds me of of a Turkish flag.
As you may see, I learned for the transit of Venus :-)

Last time I recall attempting to shoot an eclipse, I'd made up a filter using Baader film sandwiched between 2x 72mm UV filters.

essentially blocks everything else and lets in just enough sunlight to be useful.
e.g.

some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:
