Vespera Solar Filter

Astronomy by day. Watch the Sun come alive.

The Vespera Solar Filter opens the closest star to Earth to your smart telescope. Fit it on the lens, launch Solar Mode in the Singularity app and follow sunspots in near real time, in complete safety.

Why the solar filter

Safe, simple, spectacular.

Sunspots in near real time.

Solar Mode displays the Sun continuously with very short exposures, so you watch its surface as it is right now.

Follow the Sun's activity.

Capture photos at any time from the Observation tab and compare them over days or weeks. Sunspots appear, grow and fade, some lasting several days, more rarely several weeks.

Guided every step.

Solar Mode walks you through pointing and capture, so you and your smart telescope stay safe throughout the session.

Ready for the big events.

Partial phases of solar eclipses and peaks of solar activity: follow the Sun whenever it makes the news.

Safety

Three rules, every time.

1. Filter first

Always install the solar filter before pointing Vespera at the Sun.

2. Solar Mode only

Point at the Sun only through Solar Mode in the Singularity app.

3. Keep the ring closed

Never try to open the lens ring that holds the filter.

Works like a charm.

The filter is immediately detected by my Vespera, allowing me to engage the solar mode. I’m eager to experience the eclipse using this filter.
