Beginners Guide to the Sun

Item No. 890-10235
Manuf. No. Kalmbach 18543

For most of us, a quick upward glance reveals an apparently unchanging Sun. Day in and day out we watch its journey from east to west, but unlike the ancient Anasazi and Babylonians, we have instruments that allow us to measure its activities and understand its true nature. Moreover, the Sun affords amateur astronomers one of the few remaining opportunities to gather data that is useful to professional scientists. How best to get started? We all know that looking directly at the Sun without proper safeguards can permanently damage our eyesight. We must diminish the intensity of Sun's light, but more importantly, we must protect our eyes from dangerous and invisible infrared radiation. This book can show you everything a beginner would need to know about safely observing the Sun, including a brief history of solar observation, and why the Sun was so important to our ancestors.
