As examples of what I got with bracketing:

1/30 sec @ f/5.6, ISO 200



1/1000 sec @ f/5.6, ISO 200



Note that with an optical viewfinder, you'll see the prominences at the same time that you see the incredible detail in the corona, but only with your eye. The camera can't capture both at the same time, due to the huge dynamic range between them. With a mirrorless camera, you will need to physically change the settings to see the prominences or the full corona, because what you see is what you get.
