If you want something to be seen 800 miles away, it needs to be about 80 miles tall. That's at the horizon though, not above rooftops. I'd add another 50%.
A 10 mile diameter clockface would be visible but pretty small at 800 miles.
That was fun
It's all my fault...

Would a thing 10 miles wide look bigger from 800 miles than a thing 2000 miles wide from 230,000?

Air quality would affect visibility anyway, and you have to calculate curvature of the Earth.
