Our Sun

I bought a new telescope several weeks ago. It is specially designed for looking at the sun, using a sophisticated filter that only shows the sun in light of the Hydrogen alpha line of the spectrum. What is amazing about this telescope and filter is that you can see prominences on the limb of the sun, as well as areas where there is sunspot activity, and you can also see detail on the surface of the sun. It is a whole new experience to watch the sun day by day. These prominences sometimes come and go within the space of two or three hours. So here is a photograph of the entire sun, and then a cropped view showing details of just the area with prominences.
