In Part 1, the book describes the very latest thinking on solar physics in (mostly non-mathematical) detail, incorporating the latest results from research concerning the structure and behaviour of the Sun. There is particular emphasis on the surface features visible from the Earth, and how these are the result of the extraordinary processes that are taking place within the Sun.
In Part 2, the book details the techniques for observing and imaging the Sun with commercially-available equipment. The many recent advances in optical equipment now allow amateur astronomers to observe phenomena that until recently could only be seen with the extremely expensive equipment available at universities and research observatories – notably H-alpha and Calcium-K telescopes.
This is a completely up-to-date solar observing book, while providing the science background necessary for an understanding of the observations with the latest equipment. It also features the most complete solar observing and imaging guide available.

An eyepiece of 25 mm focal length is selected. With the projection magnification (11.1Â) computed, and knowing the focal length of the projecting eyepiece (25 mm), simply insert these Observing the White Light Sun Figure 3.3.

Hemisphere in which they develop. The log sheet organizes this information in the columns Gn, Sn, Gs, and Ss. Collecting this data is important because the amount of activity occurring in one hemisphere can be substantially less than what is occurring in the other. The observer in another project could determine the latitude of groups in heliographic coordinates. When the latitude of sunspot groups are displayed against time, a unique pattern, called the butterfly diagram, results. A butterfly.
Filters, allowing more of the solar continuum to pass, but it does provide an interesting view. Use of this particular filter is recommended for photography only, because of the potential for high UV exposure to the observer. 105 Observing the Monochromatic Sun Observing Tips and Accessories Solar observing is performed in conditions very different from that of the evening star gazer. For instance, the light of the Sun produces a situation where a reflection from our eye creates a ‘‘ghost.
Illustrated. The pivot point will be positioned in line with the etalon, so that the filter rocks back and forth on its edge. The spring and push/pull screw could be located several possible ways, depending on the requirements of the designer. So long as the spring and screw work against one another, a controlled degree of tilt will be given to the filter. References 1. Solar Observing Techniques, C. Kitchin, Springer-Verlag, 2002 2.
