Seymour Solar makes the finest, yet most-affordable solar filters we’ve ever tested- starting at just $95/pair. Their Helios thin-film has a consistent yellow-orange solar image, with higher contrast than competitor’s filters. We also offer Seymour Premium Glass filters, for highest-possible resolution. The glass filters are recommended when doing photography using a Novagrade Smartphone or Tablet Adapter. Our Seymour filters come with custom felt tape added to the inside of the aluminum cells, for a snug slip-on fit with our binocular telescopes. Sold in pairs. All filters meet ISO 123112-2 requirements. No returns accepted for solar filters.
