Awesome Astrophotos: A Negative Sun

[/caption]

Here’s an unusual if not stunning way to look at the Sun: César Cantu from the Chilidog Observatory in Mexico has taken a few images of the Sun, and reversed the colors, or made a negative. This increases the contrast and allows structures to be seen — or at least stand out — that otherwise are not visible.

“The picture is made under normal procedure,” César tells us. He creates an Avi file, then reverses the colors, and also applies false color, leaving the sky to look blue and the Sun to yellow-orange and the chromosphere as red. “This is to delight the author!” César says.

The solar prominences, in all sorts of shapes and sizes, really stand out.

Below, you can see a comparison of “normal” image which has then been “negativised.”

Thanks to César for sharing his stunning images. See more at his website, Astronomía Y Astrofotografía.
