About observing the Sun
The stars in any telescope are visible as points, since they are at a giant distance from us. The only star on which you can see at least some details is the Sun.
In this article I will talk about ways to observe the sun. The jokers and those who are not in the subject will say – “Y-s, you can look at the Sun in the telescope 2 times – once with the right eye, and once with the left!”. And there is some truth in this – IN THE USUAL TELESCOPE WITHOUT SPECIAL PROTECTIVE MEANS (SOLAR APERTURE FILTER) WATCH IN THE SUN IT IS UNACCEPTABLE! The concentration of sunlight at the focus of the telescope and at the exit from the eyepiece is so high that you can instantly and forever lose your sight. So be careful, do not leave the telescope unattended to children, and ALWAYS tell them that IN THE SUN, WATCH IN THE TELESCOPE IS IMPOSSIBLE! NO HANDMADE FILTERS – NO “DISCS”, NO CDS, NO MASK OF WELDERS, NO TONING FILM – ONLY RELIABLE FIXED APERTURE FILTER FROM A SPECIAL FILM OR CLEAN!
Only sometimes, when the Sun is on the horizon, due to the absorption of light in the atmosphere, the brightness can decrease to a safe level, however, viewing without a filter can still be dangerous.
So, he told about precautionary measures, now we turn to the methods of observing the Sun.
