Vaonis AC021 Solar Filter for Vespera (Black)

Astronomer by night, an astronomer by day. Observe the closest star to Earth during the day with the Vaonis AC021 Solar Filter for Vespera. The filter allows you to observe sunspots (dark spots) that show the intensity of the Sun’s activity. The Solar 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.Observe SafelyThe 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 Mode of the Vaonis Singularity app, to ensure the observation runs smoothly and that you and your instrument are safe.Instructions for UseTo use the Solar Mode mode, your instrument must have been used at least once at night for the solar pointing to work. Designed specifically for Vespera, the filter fits easily and discreetly into the optical arm. During daylight hours and with the Vespera lens protected from direct sunlight, remove the standard lens ring and replace it with the solar filter until you hear a click. The fixing ring that holds the solar filter is equipped with an electronic card that allows Vespera to detect it. To verify that the solar filter is properly positioned, connect Vespera to your mobile device and launch the Singularity app. In the Space Center, click on Solar Mode and follow the step-by-step guide.Maintenance TipsThe 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..
