I know next to nothing about this, and can’t comment on the hardware, but looking at the even illumination on the Chris Hooker photo, I wonder what his raw image(s) looked like and if or how he processed them ?
When dealing with some solar eclipse photos a few years ago I used a “radial blur and subtraction technique” which gives a more even illumination and increases the contrast, that should solve the limb darkening.
