Sunflower X-ray photos revisited

How to show the sun in the middle of a sunflower ? For astronomers it is quite common to look at the sun in hydrogen alpha light, which is a pure red at 635nm. With artistic eyes, a red center might be overdone.

So I tried two different representations, one in BW that is close to the natural look and feel of a sunflower and one with a light blue in the center as complementary color to the yellow petals.

The surface structure of our sun can be seen like astronomers see it.

There is no photo of the next digital X-ray image of a sunflower with its stalk and a leaf:

I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.
