I have looked at the sun with #9. That is not enough. 10 is a big push. 11 and up are comfortable. I would not use autodarken. Even if trustworthy, they would sacrifice some clarity. My wife and I will be using #11 and #12 glass gold flashed welding filters.
I think #14 would be for long term staring at the sun. We will not.
I went out and looked today. You're right, 9 is for a glance, 10 is for a few seconds and my auto is a no-go. I think I will get a couple of 14's for the 2 of us.
