Yes, but neat. To observe the Sun, either light-shielding films or special Coronado telescopes are needed. They are expensive, but only with their help you can see the solar prominences and the structure of the sun’s surface. If you observe the Sun through a telescope without protection, you can lose your eye – and ordinary dark glasses will not help here.
How can I find out about flights of the ISS, satellites and other interesting things?
Also using applications. There are applications for warnings about ISS flyby or Iridium flares. Advanced users may need heavens-above.com to help keep track of spacecraft. Thanks to these applications, some virtuosos start racing for original footage and try to catch the ISS and other large satellites against the background of the Sun or Moon, or even planets. In the VKontakte community, Observational Astronomy will always tell you about the upcoming interesting events in the sky: about confrontations, passing comets and asteroids, meteor showers, polar flares, rocket launches, falling pieces of space debris and much more.
