This is a truly Highlight-Experience: if you live in a big city then you will be amazed by the Southern Hemisphere Milky Way in it’s splendor. Imagine counting up to 6.000 naked-eye visible stars instead of the 30 that you may see in the urban light polluted sky – it is a big WOW!!!
We will go through the beauties of the night sky – looking for planets, stars, shooting stars, satellites, constellations and galaxies. We may elaborate on life outside Earth – based on Science and Philosophy, including the Fermi Paradox.
“Selfie-of-the-Stars”: an unforgettable picture of the group with the stars in the background taken with state-of-the-art photographic equipment will be handed over with resolution for social media usage (digital file).

An exceptional Astronomical tour with Professor Egon Filter, a unique experience. We had the opportunity to enjoy the sunset and observe the Milky Way and the constellations, as well as the passage of several falling stars (Meteors) and some satellites. Professor Egon Filter led very well the group is very good in storytelling and historical facts about the region of South Cambara and about the formation of the universe.

It was the most wonderful thing that we chose to do, to see the Milky Way with the naked eye, infinite stars Professor Egon is the best in storytelling we already know, and explained everything very well, finally we loved and would return and recommend to all who could and want something different and beautiful.

Our evening of 18/04/2026 in Cambará do Sul gained a special glow with Professor Egon’s astronomical tour. If the sky in the region is already breathtaking due to the absence of light pollution, driving the Egon turns everything into an unforgettable experience. With a deep knowledge and an incredible didactic, he explains the universe with lightness and good mood, capturing the attention of everyone without engaged scripts. The big difference, besides the class under the stars, is Egon's talent with the camera. He is able to capture photos of the participants with the night landscape that look pure magic: the effects and the sharpness of the stars around us create artistic records that no ordinary camera would accomplish. We left there with the soul washed and full of memories of rare moments of contemplation. Gold tip: go with warm clothes (take it seriously when he says it) and prepare to get excited. It was, without a doubt, the highlight of our stay in the Campos de Cima da Serra! We are indicating to all friends and acquaintances that we know that you will go to Cambará!

Imperdible!!! It was wonderful and very beautiful. Our Egon guide is a storytelling. I possessed a lot of knowledge of the subject, tells us and gives a show of the theme of the tour. I recommend you take the Astronomical Tour, there is no way to explain how gratifying it is just with words. I attach photos to show a little bit of what I experienced. Super recommend.
