If only.
I don't have a tracking mount on my tripod, so that cursed rascal of a sun kept moving. I cropped the photos to minimize movement but clearly could have done a better job. I also don't have enough additional frames to smooth it into a video-like look, as I was actually watching the process as well as capturing it. That GIF is around 30 frames. I know there are other more professional captures out there that are a lot smoother than mine.
The corona is only visible from Earth during a total eclipse because the central body of the sun is much (
much) brighter. It's only when that is blocked that we can see the chromosphere and corona.
The diamond ring and Bailey's Beads are visible both before and after totality. Just for a very short period. I would imagine people are more likely to capture the tail end than the beginning.
