At 1,780 meters altitude, on Col Drusciè at the foothills of the Tofane, the Astronomical Observatory of Cortina d'Ampezzo is one of the most interesting places in the Dolomites to approach astronomy and observe the sky under particularly favorable conditions.
Managed by the Cortina Astronomical Association, the observatory takes advantage of the privileged position of Col Drusciè, characterized by clear sky and very low light pollution. Here, enthusiasts, families, students and visitors can discover planets, Moon, Sun, stars and deep sky objects through sophisticated astronomical instruments.
The observatory is also engaged in supernova research: as part of the CROSS program (Col Drusciè Remote Observatory Supernovae Search), 41 supernovae and a small planet have been discovered, named "Cortina d'Ampezzo".
Where the Astronomical Observatory of Cortina is located
The Observatory of Col Drusciè is located on the homonymous hill, at approximately 1,780 meters altitude, above Cortina d'Ampezzo and at the foot of the Tofane group.
The high-altitude position is particularly suitable for astronomical observation: the distance from major light sources and the clarity of the sky allow for clearer observation of celestial objects.
It is an interesting destination to include among the things to see in Cortina d'Ampezzo, especially for those seeking an experience different from traditional mountain activities.
What can be observed
During activities open to the public, the observatory allows observation of various celestial bodies, depending on weather conditions and the visit program.
Through the telescopes it is possible to dedicate yourself to observing:
- planets of the Solar System;
- Moon;
- stars and constellations;
- deep sky objects;
- galaxies;
- Sun, through a specific solar telescope;
- phenomena on the solar surface, such as sunspots, granulation and prominences.
The experience naturally changes depending on the season, time of visit and sky conditions.
The telescopes of the Col Drusciè Observatory
In the two domes of the observatory various instruments are installed dedicated to both outreach and astronomical research.
The main one is the Ritchey-Chrétien "Officina Stellare" 40 cm telescope (16" f/8), used for visual observation of the deep sky and planets and for imaging galaxies as part of supernova research. This instrument replaced the previous and historic 50 cm Newton telescope, which remained in service until 2015.
Next to the Ritchey-Chrétien is a Celestron Schmidt-Cassegrain 28 cm (11"). The instrumentation is completed by a "Veloce" astrograph 20 cm (8" f/3), designed for wide-field observations and comet imaging, and an Airy apochromatic refractor 12.7 cm (5") with Coronado filter, dedicated to observing the Sun in H-alpha.
The observatory also has the control software COMETA – Col Drusciè Observatory Management for Easy Telescope Astronomy, developed by engineer Sergio Pascolini, which allows the telescope to be controlled easily even by beginners.
Sun observation at Col Drusciè
One of the most interesting experiences for those visiting the observatory during the day is Sun observation.
A special solar telescope allows you to observe the Sun safely, without looking directly at it and without using equipment not specifically designed for this purpose.
Depending on solar activity, it is possible to recognize phenomena of the photosphere and solar atmosphere, including sunspots, granulation and prominences.
Morning openings dedicated to Sun observation are scheduled on specific dates: it is therefore advisable to check the updated calendar before planning your visit.
Supernova research
The Astronomical Observatory of Col Drusciè is not just a place dedicated to outreach. Members of the Cortina Astronomical Association also conduct research activities, with particular attention to galaxy observation and supernova research.
The CROSS – Col Drusciè Remote Observatory Supernovae Search program has led to the discovery of 41 supernovae, as well as a small planet subsequently named "Cortina d'Ampezzo".
This scientific activity makes the observatory a special reality in the panorama of Italian amateur astronomy, where the passion for sky observation is combined with concrete research activity.
How to reach the Col Drusciè Observatory
The observatory is easily accessible from Cortina d'Ampezzo thanks to the Tofana – Freccia nel Cielo cable car, during opening hours and operation of the facility.
In summer
During the summer season it is possible to reach the Astronomical Observatory of Col Drusciè:
- with the Tofana – Freccia nel Cielo cable car, departing from Cortina;
- on foot from Piè Tofana, with a walk of about 20 minutes, following the marked trails, including the Planets Trail and the Universe Trail.
The walk allows you to combine a visit to the observatory with a scenic excursion at the foothills of the Tofane.
In winter
During winter mornings, the observatory is accessible only by the Tofana – Freccia nel Cielo cable car and not on foot.
Before departure it is always advisable to verify the opening hours of the observatory and those of the cable car, which may vary depending on the season.
Useful information for visiting the Observatory
The Astronomical Observatory of Col Drusciè organizes throughout the year visits and activities for the public, aimed at both enthusiasts and those approaching astronomy for the first time.
For Sun observation, public openings take place on specific mornings indicated in the official calendar. For these visits reservation is not necessary and the ticket indicated by the Association is €5 per person.
For other types of visits it is important to check in advance dates, times, access methods and any reservation required, by consulting the updated calendar of the Cortina Astronomical Association.
A panoramic point over the Dolomites sky
The Astronomical Observatory of Col Drusciè is an original destination for those staying in Cortina d'Ampezzo who want to experience the mountains even after leaving the trails.
At almost 1,800 meters altitude, with the Tofane in the background and a sky particularly favorable to astronomical observation, Col Drusciè allows you to discover the Dolomite landscape from an unusual perspective: not only by looking at the mountains, but also by exploring the Universe through the observatory's telescopes.
To organize your visit: always check the official calendar of openings and cable car hours before reaching Col Drusciè.
