About the observatory

In the Kennemerduinen between Haarlem and Zandvoort lies Volkssterrenwacht Copernicus, where we welcome visitors for free since 1974 to experience the universe up close. Through our telescope, you can observe the moon, planets, stars, and the sun during the day.

There's always something to do, for young and old, even when it's cloudy. We offer lectures, a changing exhibition, courses, and an astrophotography working group.

The observatory is entirely run by volunteers and is recognized as a public benefit organization (ANBI non profit).

Additional solar viewing days in May 2025

In the month of May 2025, the observatory will be open every Saturday afternoon for the first time, from 1:00 PM to 4:00 PM. You can safely observe the sun through our telescopes during that time.

For years, we’ve debated whether it was still worthwhile to stay open in the evenings during May, since it doesn't get dark until very late. That’s exactly why we’re trying something new—shifting more focus to the sun. This is actually the perfect time of year to observe the sun.

Now in 2025, solar activity is at its peak, meaning you can see many sunspots and solar flares. You can learn more about why this happens in our exhibit at the observatory, which will be on display until the end of May.

Entry Course Astronomy

Twice a year we organize an Entry Astronomy course. It starts in September or January. With this course, you will gain a good general understanding of astronomy. The course is intended for a general audience and does not require any special prior knowledge.

In this course, topics such as Sky Orientation, Origin and Life Cycle of Stars, The Birth of the Universe, and much more will be covered. Additionally, there will be two practical evenings where you will have the opportunity to observe through our telescope and learn to use a planisphere
