The Sun 5 August 2019 White Light

Recommended Posts

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

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 :).
