Sunrises and sunsets are popular photo motifs. Never look directly at the sun! If you want to observe the sun with a telescope, you need special filters before you can look through the telescope. White light solar filters filter out the infrared and ultraviolet and reduce the remaining light to a fraction, so that the sun may be viewed without danger. Then you can see the dark spots of the sun. For prominences, an Hα filter is needed, which only lets through a very narrow part of the spectrum. Only in this line are the faint prominences visible. The bright photosphere below is cut out. February 1991 to August 2022, 42 photos.
