Astronomical Observatory

Under the dark skies of the Apennines, a prime spot for stargazing.

Sky, science and passion, tailor-made for the valley

Amidst the slopes and hills surrounding Carrosio, the sound of the wind, the silence of the night and the glow of the stars come together in a special place: the Carrosio Astronomical Observatory. It is not a major academic centre, but a cultural, scientific and community hub that transforms the sky into an open door to the universe.

The origins: a dream come true

The observatory was conceived and built by Claudio Ferretti, originally from Novi Ligure. It is a labour of love, where a passion for the sky and the belief that “the stars belong to everyone” have come to fruition in the creation of a shared observatory. His work stands out precisely for its local, voluntary nature and its focus on community involvement.

How it works and what it offers

The observatory is open to the public on special occasions: events, astronomy evenings and night-time walks that take visitors along a path (about 2 km from the centre of Carrosio, with an elevation gain of about 150 metres) to the dome or the telescope station.

During these evenings, under the guidance of Ferretti himself and local amateur astronomers (such as the GAST, Gruppo Arquatese Astrofili), stars, planets and deep-sky objects are observed, or – if the sky is overcast – archive footage is projected onto a large screen.

The main instrument – or at least one of the telescopes used on these occasions – is made available by the amateur astronomers, with public viewing and informative commentary.

An intriguing detail: Claudio Ferretti, through his own observatory, managed to photograph a star “never captured before”, which was then “catalogued by NASA”.

Challenges and prospects

The observatory faces some typical challenges:

Light pollution: the lights of the village and the valley can severely disrupt highly sensitive observations.
Weather conditions and visibility: cloud cover, humidity and mist are relentless enemies of amateur astronomy.
Sustainability and maintenance: the telescope, the dome and the mechanisms require care, upgrades and resources.
Community involvement: ensuring the community views the observatory not as an isolated curiosity, but as part of its own ‘sense of place’.

Local significance and value

The observatory offers various levels of significance:

Educational/outreach: it encourages non-experts to look at the sky with fresh eyes.
Cultural/identity: it adds an astronomical element to Carrosio’s heritage, complementing geology, history, landscape and faith.
Experiential tourism: the stargazing evenings attract visitors interested in “sky tourism”.
