The initialization of Stellina and Vespera requires four main steps, which can be followed in the Stellinapp. 2.2 Stellina / Vespera: automatic initialization with astrometric calibration With Stellina and Vespera, sky syncing is achieved within 2 or 3 minutes by simply pressing a button. Then the telescope can calculate the stars’ position and activate its motors to point and follow the lead to observe. The mount axis must also be aligned in a particular way.
Time and geographical location must be taken into account. Using a telescope to capture images of the universe requires accurate synchronization with the orientation and rotation of the sky. Above all, one particularly long and complex step of the process with a classical telescope that is fully automatic with Stellina and Vespera is the syncing with the celestial sphere.Īs explained previously, the appearance of the sky is constantly changing. The main reason is that they are fewer manipulations to perform. The start-up of Stellina and Vespera is much quicker than that of a classical telescope: less than 5 minutes in good conditions versus more than 1 hour for classical equipment. What is the initialization of a telescope? 2.1 Why is initialization necessary? This adjustment is required for more efficiency in pointing and tracking. Stellina’s bubble level allows the telescope to be set horizontally. In any event, under these conditions, most observations are impossible. In case of heavy cloud cover, initialization may fail.
However, the initialization duration of Stellina and Vespera can be shorter if it is a very dark night. The observation stations can initialize from the nautical twilight when the sun goes down 6° below the horizon. It is not necessary to wait for complete darkness.
Requirements for a successful initialization 1.1 External conditionsĪpart from solar observations which require appropriate filters, initialization of the two telescopes for night observation requires a dark enough sky and visible stars.
