Sun Through Two Telescopes

These images of the Sun's Chromosphere were both taken on the afternoon of March 29, 2011, using two different hydrogen-alpha telescopes. 

The image on the left was taken with a 100mm hydrogen-alpha telescope, while the image on the right was taken with a 60mm hydrogen-alpha telescope equipped with a double-stacked filter increasing the contrast of the surface features. The normal hydrogen-alpha telescope shows details of prominences and Sunspots much clearer, while the double-stacked filter allows for more contrast between the filaments and bright plages on the Sun's disk.
