Guide de l’observation solaire avec un spectrohéliographe

The Sun, a nearby and dynamic star, offers a wealth of observations that are accessible thanks to appropriate techniques. This book introduces spectroheliography, a method now available to amateurs, for studying our star in detail. With Sol’Ex, the Solar Explorer, a compact and lightweight instrument designed by the authors, transform a simple telescope into a powerful observation tool. Observe a living Sun: its spots, eruptions, spectacular prominences, magnetism, helium atmosphere, and even its corona, now visible outside of eclipses.
More than just a practical guide, this book reveals the principles of spectroheliographs and spectroscopy, illustrated with concrete examples and clear diagrams. The authors guide you through a comprehensive educational journey, accessible to beginners and students alike.
The authors share their expertise here. Their approach, both precise and accessible, gives you the keys to observe, understand and interpret the Sun in a new light: a scientific and visual adventure that is accessible to everyone!
