Using my Sol'ex (version 1) I'm able to observe line broadening in sunspots. As shown in the image, the spectrallines in sunspot 3759 (upper picture) is bolder and broader that the line in the photosphere (below of the picture). The phenomene is due to magnectic activity in sunspots and becomes visible in metalic spectrallines; in this case Titanium, Calcium and Iron.
