Description
Astronomer by night, astronomer by day! Observe the closest star to Earth during the day with the Stellina solar filter. The filter allows you to observe sunspots (dark spots) that show the intensity of the Sun’s activity.
Photograph the Sun with Stellina
The Solar Pointing mode allows you to observe the Sun in almost real-time using the live display*. Capture photos at any time from the Observation tab of the Singularity mobile app.

Take several shots at different times of the day, week or month and compare your photos. Witness how the Sun’s activity changes with the appearance or disappearance of sunspots. These can have a life span of several days, more rarely several weeks.

- Automatic video recording for solar/planetary observation is not yet offered in Singularity. To make an animation, retrieve your photos in jpg format from Stellina’s with your USB drive and put your photos together using photo/gif animation software.
- The Solar Pointing mode is not yet suitable for observing solar eclipses.
Observe safely
The filter is made of a metalized foil with a dimming effect. It will reduce the amount of light and allow you to observe the Sun in a way that is safe for your instrument. You will be guided through every step of your adventure by the Solar Pointing mode of the Vaonis Singularity app, to ensure the observation runs smoothly and that you and your instrument are safe.

Warnings
- Your Stellina station should never be pointed towards the sun unless a solar filter is installed.
- You can only use Stellina to observe the sun using the Solar Mode feature of the Singularity app and the solar filter specially designed by Vaonis. The use of any other means to observe the Sun (pointing by coordinates, pointing by hand, use of any other filter, etc.) would void your warranty in the event of damage to your equipment. (see Warranties tab).
- Never look directly at the sun without adequate protection. Direct observation of the sun without protection and without a solar filter, even for a short time, can lead to serious eye burns and potential loss of vision or even blindness.
- Do not attempt to open the lens ring that contains the filter (see Warranties tab).
*Continuous display of photos with a unit exposure time of 250µs
Instructions for use
Introduction: In order to use the Solar Pointing mode, your instrument must have been used at least once at night for the solar pointing to work.
Designed specifically for Stellina, the filter fits easily and discreetly into the optical arm. During daylight hours and with the Stellina lens protected from direct sunlight, push the solar filter into the housing of the optical lens of Stellina, so that the black seal is completely inserted.
In the Space Center, click on Solar Pointing and follow the step by step guide.
Maintenance tips
- The filter is delivered in a transparent storage box. Store the filter in its box after each use to avoid dust build-up.
- If you notice any streaks or dust, gently clean the filter with an anti-static cloth, feather duster or air blower.
- To avoid damaging the surface coating, do not spray the filter with cleaning agents, but use a mist instead.
If your Stellina or the Singularity app detects a problem when installing the filter, you must immediately stop observing the Sun and start the installation of the solar filter again following the instructions on your device and the instructions for use. If the problem persists, you can visit our website www.vaonis.com/contact to contact our support department.
Observing the sun without following the instructions above and the instructions for use presents a high risk to your instrument, including the risk of overheating its components and the risk of fire. You are also exposing yourself to a significant health risk due to possible unprotected viewing of the sun which can lead to irreversible eye damage.
