Ready for the August eclipse

I lost the original solar filter supplied with the Hestia Premium kit which I purchased for the 2014 solar eclipse during an accident whilst observing outdoors, so ordered the Hestia Solar Kit from Vaonis. The kit arrived in a few days from France to the U.K. and I am now ready to observe and image the Solar Eclipse in August 2026.

A top rate service.

I am new to observing stars, the Sun and Moon and found that I required a Sun filter for my Vaonis. I found my item on the website and found the description very helpful and accurate and noting assistance was available. I made my purchase late at night and the next day I was informed it had been packed and despatched to me. Within two days I was in receipt of my filter and ready to use. I would buy again from the website without any hesitation.

The instrument that proved itself during the solar eclipse of 2024.

During the total solar eclipse of April 2024, thousands of Hestia users across the United States captured the corona, Baily's beads, and the chromosphere with nothing more than their smartphone and Hestia's optical system. Images that would have required professional equipment a decade ago, now achievable by anyone.

How to observe the sun using my solar filter?

Solar observation must be carried out with Vaonis solar filters. Never look directly at the sun without the filter, as this could injure you or damage your phone.

  1. Select solar mode from the camera menu.
  2. Install the Vaonis solar filter by screwing it onto the front of Hestia.

The image will turn black, with only the sun remaining visible after the filter is installed.

How to attach the solar pointer?
  1. Attach the Solar pointer to Hestia.
  2. Aim at the sun with Hestia, using the tripod.
  3. Use the solar pointer's shadow to help you aim at the sun.
  4. Once the sun is centered on the screen, fix the tripod's altitude axis.

⚠ Never look directly at the sun with your naked eyes, as it can cause serious damage to your vision.
