Frequently Asked Questions
About the telescope (tech specs)
Our telescope includes all the elements necessary for astrophotography. The optics, the pointing and tracking system, an embedded computer, an image sensor and motorization. There is also a compartment to accommodate a powerstation type battery.
Stellina has a mobile app that enables you to fully control your telescope using a smartphone or a tablet. With an internet connection you can share your pictures on social media or within the Stellina user community. You can also join our online community to share advice, improve images and learn more about astronomy.
Once positioned on a stable tripod, start and connect Stellina to your smartphone. Thanks to its star-field detection system, Stellina is able to locate itself in the sky. In less than 5 minutes, you are ready to shoot.
A guide sensor is integrated into the instrument. The embedded computer decides which target star is the most suitable and tracks it. You are notified of the smooth operation of the tracking by our mobile application.
When the temperature changes, it may cause a change in focus. To correct this, Stellina integrates an autofocus system. In this way, you can go to sleep with peace of mind, your pictures will benefit from a perfect focus throughout the night.
There are two modes in Stellina:
1) The automatic mode applies the best acquisition parameters and starts the image acquisition. When they reach the embedded computer, it processes them automatically and displays the result.
2) The manual mode allows you to customize the parameters of the acquisition (exposure time, sensitivity, number of poses …) and recover the raw image files that you can then process with your favorite software.
Fogging, lens condensation or dewing is a well-known problem in astronomy, too often responsible for interrupting observations. To handle this problem, Stellina incorporates a heating resistance system (dew heater) that activates automatically to ensure you always have a dry optic system!
The power consumption of the instrument is about 2A. Therefore, a battery of 10 000 mAh assures you an autonomy of about 5 hours. If you prefer, it is possible to connect your Stellina directly to the mains thanks to the power supply that is included.
Stellina has a built-in Wi-Fi connection. You do not necessarily need an internet connection to connect to Stellina. The telescope is like a residential (home) gateway to which you can connect via a Wi-Fi connection.
Essential for the proper operation of the instrument, the field derotator is integrated and controlled by the onboard computer. Depending on the target star, the rotator adapts its rotation speed. This also changes the sensor field to achieve perfect framing.
Stellina is a smart and future-proof telescope. Over time, new functions will be developed to improve its performance and increase your pleasure! To achieve this, the application is updated automatically and if Stellina itself requires an update, it is automatically installed via the mobile application.
Fully integrated devices usually suffer from the problem of being unable to evolve. Stellina is different. The battery can be changed by accessing the dedicated compartment and the sensors can evolve. To achieve this we will propose evolution kits. The principle is simple, each kit includes the transportation of your instrument to our offices, the installation of the sensor of your choice (from the list of available sensors), the installation of the latest version of the embedded software and a full revision of your instrument.
About the use of Stellina
No, the device is designed to be used by both amateur and advanced astronomers.
Yes. The telescope is equipped with a light pollution filter that lets you observe the sky in the city center, from a garden, a roof or a balcony, as if you were under a remote country sky.
Thanks to its ease of use, you could think that Stellina is for beginners, but you’d be making a serious mistake! Its simplicity makes the telescope accessible to beginners but also meets all the needs of the advanced amateur astronomer. Our mission is simple: to help you discover, progress and excel with a single telescope.
Our telescopes are very safe devices and are suitable for beginners up to experienced amateur astronomers. The minimum user age we recommend is 8 years old but young children should always be supervised by an adult.
Yes, it is possible if you use your 3G/4G connection or an Ethernet cable. It is not possible to use your Wi-Fi connection because it’s already used to connect your mobile device to Stellina.
Yes, you can connect multiple smartphones and tablets to Stellina at the same time. One of them will be designated as the administrator and the other users will be able to see the pictures taken by the instrument.
About the pictures
Yes, Stellina is a telescope for astrophotography. Taking photographs is the only way to observe the sky with the instrument. Modern high performance sensors and an increasingly polluted observation environment pushed Vaonis to make this choice.
Stellina is a so-called “large field” astrograph (astrographic camera) because its field is about 1° x 0.7°. To get a better idea, the sun and the moon represent a field of about 0.5°, so they perfectly fill the field of the sensor. Stellina is designed to take pictures of deep sky objects: galaxies, nebula, star clusters or comets etc. However, it depends on their apparent size, not all stars are observable (no single telescope can observe everything) but a catalogue of hundreds of stars is already waiting for you!
Constellations cannot be photographed because they are too large to fit into a telescope field. These types of images require a simple camera.
The planets have a very small apparent diameter (eg, about 0.01° for Jupiter), making it impossible to observe using Stellina. It will be possible to distinguish the rings of Saturn and the bands on Jupiter but nothing more than that.
There are two ways to retrieve the images: either by getting the final image in JPG format or by retrieving the unprocessed raw files.
We will first ship to Metropolitan France and all European Union countries, followed by Canada and the United States. If you live outside the EU and wish to order our products, feel free to send us a request by email. We will do our best to meet your requirements.
If for some reason you want to return your products, you can return your merchandise to our office up to 14 days from your item’s ship date.
Our telescopes come with a two-year guarantee.
In case of breakdown or breakage, we invite you to contact our service department. After a diagnosis with one of our technicians, your telescope will either be repaired remotely through a software upgrade or sent back to our factory for repair.
About the mobile app
The mobile app, developed by Vaonis, is supported on Android, iOS and Windows 10.
Yes, you can download the Stellina mobile app for free. We will keep you updated when it is available on the app stores.
We regularly attend events, tradeshows or stargazing parties to present Stellina to the public. We suggest you subscribe to our newsletter or follow us on social media to be informed about our upcoming events. If you’re organizing an event and wish us to give a product demo, feel free to send us an email at firstname.lastname@example.org
Stellina is entirely assembled and configured in Montpellier, in the South of France.
