Today's Sun at noon in very poor seeing - the image was boiling all over the place!

Ignorant, but genuine question: What do you mean when you say 'white light'?

 

[Bizibilder]

In "white light" viewing or imaging all wavelengths of light are observed.  The only filter used is to reduce the amount of that light to a safe level.  In my case I use a Baader ND5.0 solar filter, a Herschel wedge has the same effect but using a prism (and often additional filters).  In my images above you should note that even though the images are taken with a normal colour DSLR camera the orange colour is entirely false!  The true "colour" of the image is seen in the image with the Long/Lat grid superimposed.

Thanks Bizibilder.

I was thinking along those lines, but have learned from experience that my first line of thought on AP matters is often wrong :).

Despite the conditions, that is still a nice sharp disc.
