Video: Solar observation with telescopes and filter tips (with English subtitles)

October 19 2022, Marcus Schenk

Want to observe the Sun? Welcome to the solar observation club!

In this video we show you how to easily observe the Sun, sunspots or solar prominences using your telescope. Additionally, you will learn which filters and what additional equipment you need for this. Finally, fantastic images of the Sun await you. A guide for beginners and other fans of our central star. Solar observation is fun!

But beware… Never observe the Sun without a suitable solar filter! And never leave children unattended with a telescope or binoculars near the Sun!

Good to know: We will have a partial solar eclipse on 25 October. Secure your solar filter and solar eclipse glasses now – our stocks are limited.

From the video:

 

  1. Take care when observing the Sun
  2. What you must consider
  3. The technique of white light observation
  4. What is it and what can you see?
  5. Which filter works for me?
