Comment by OP:
I shot this image using the equipment listed below. While editing my results, I just kept pushing harder and harder into the details of the solar chromosphere. The chromosphere is a visible layer of hydrogen plasma which aligns itself with local magnetic field lines. As I ventured further down this road it became clear that the end result becomes somewhat of a visualization of this field. Plus, it just looks pretty cool.
This walks the line between science into art, perhaps blurring it a bit. What do you think?
