Jürgen Marsch,Jörg Fritzet shows sunspots and other features that displaya wealth of fine detail and change their appearance strikingly from day to day. But observing the Sun can be dangerous. NEVER look at the Sun through a telescope or other optical aid, even for a brief instant. The Sun‘s intense radiation, amplified and

Jürgen Marsch,Jörg Fritzeugh, as I have explained in Chapter 4, it is very difficult to do accurate positional measurements using photographs. Nevertheless, photographs of the Sun’s full disc are excellent for showing what was visible on the Sun on a particular day and show the appearance of the Sun’s features far more real

Even in good seeing, when the image is relatively steady visually, close-ups of sunspots and other solar features can be disappointing because they were taken when atmospheric turbulence affected the image.
