Eclipse glasses you will wear
Observing the sun with the naked eye is prohibited so as not to damage the retina. During a solar eclipse, it is therefore recommended to use solar filters sold most often in the form of cardboard glasses.
During total solar eclipses, it is possible to remove your eclipse glasses during the whole phase (when the lunar disc completely covers the solar disk) to enjoy the natural beauty of the phenomenon. Be careful, it will only last a few minutes!
These solar eclipse glasses are specially designed for sun observation. They must meet an international ISO standard or have the CE mark, which certifies that glasses are suitable for direct observation of the sun, such as during an eclipse.
Beware of fake and misleading advice! Do not use X-rays, slides or multiple layers of sunglasses, as you may sometimes hear. If your solar eclipse glasses are damaged or scratched, it is recommended to use another pair.
Solar filter you will use
Never look at the sun and an eclipse through a camera, a telescope, binoculars or other optical instruments, even with sunglasses. Again, damage to your eyesight (and your device) could be very serious! A famous saying expresses it well, “we can observe only 2 times an eclipse without filter, once with the right eye, once with the left eye” … There are solar filters specific to astronomical instruments that filter the ultraviolet and infrared rays and reduce the brightness of the sun entering the eye or the sensor. As with the naked eye, the solar glasses can be removed during the brief period of totality, giving you the opportunity to capture every detail of this unique moment. If you plan to immortalize this phenomenon using a camera, we advise you to train, for example on the moon, to optimize the setting of your device.
In advance you will prepare
Solar eclipses are popular astronomical phenomena that attract many curious but also true enthusiasts. These eclipse hunters can book their trip more than a year in advance and travel more than two weeks before the eclipse to the best viewing spots to get the best location. As a result, the best locations become crowded very quickly. Depending on the popularity of the observation point, prepare your schedule in advance. Also follow the weather forecast! You just have to hope that the sky is perfectly clear.
Stellina, a solar version in project
A version of Stellina designed for solar observation is being studied for future development. It will work on the same principle as the first telescope designed by Vaonis: an all-in-one telescope, sleek and remote controlled using a mobile device to photograph the sun. This next version will only be used for the observation of the sun and will let users capture solar eclipses or sun eruptive prominences, becoming the first all-in-one telescope dedicated to solar photography. We’ll give more details soon!
