Observing the Sun in H Alpha


If you are a beginning solar observer like me, or you consider becoming one, you maybe asking yourself: what can I see on the Sun when observing in H-Alpha with a special telescope like for instance the Coronado PST. I found this wonderful article by David Knisely, Observing the Sun in H-Alpha, on the web last week. In this article, David not only shows some great images that let you see what to expect when observing the Sun in H-Alpha, he also explains all the different features like prominences, filaments, active regions, flare's, plage's and others you might observe. follow this link to read David's article.
