Observing the Sun is an activity that many amateurs do, and contrary to what it may seem, it can be quite rewarding and attractive. Our star does not remain unchanged, but from time to time changes occur on its surface, which can be appreciated with a telescope or binoculars. The most characteristic is the presence of Sunspots, colder areas of the Sun that constitute sources of high magnetic activity and they are of special interest to astronomers who professionally study our star. The observation of sunspots is interesting for the amateur, since it is possible to follow them over the days and notice their changes, both in size, shape and movement on the surface, from which it can even be obtained!the rotation period of the Sun! Therefore, observing solar activity can be extremely interesting and entertaining.
Additionally, solar observation can also be used for moments of special interest: solar eclipses (total, annular or partial) and transits of Mercury and Venus. They undoubtedly represent a very good experience and allow us to closely study these phenomena, which we only sometimes have the opportunity to witness. Before starting with the instructions, pay attention to this warning!
| NEVER look straight at the Sun. Prolonged exposure to the naked eye can cause irreversible damage to vision; Exposure through a telescope eyepiece, finderscope or binoculars, even for fractions of a second, can cause permanent blindness. |
