We will let our imagination fly while the view through the telescope takes us from the impressive observation of planets of the Solar System, to the always delicate structure of planetary nebulae, the sphericity of globular clusters or contemplating the light of the most distant galaxies.

Approximate duration

5 hours


125 euros/person. Single price


– The temperature inside the telescope dome is practically the same as outside. It is essential, even in summer, to go to this activity perfectly dressed, so that the cold does not spoil the enjoyment of such a unique experience.

– Due to both the conditions inside the dome and security measures, the minimum age for admission to this activity is 12 years old.

– If you do not have experience observing through telescopes, it would be very important to consider participating beforehand in any of our astronomical observation activities “Discover the Sky of Calar Alto”. Viewing through a telescope with an aperture as large as the 1.23m is much better appreciated and interpreted after experience with smaller telescopes, which also provides appropriate context and comparison.
