Acuter ST 40/400 Elite Phoenix 40 Solar Telescope

Acuter ST 40/400 Elite Phoenix 40 Solar Telescope

Acuter Phoenix 40mm is a Solar H-Alpha telescope for narrow-band observation and photography of the Sun. This instrument makes it possible to explore extraordinary solar surface dynamics that go far beyond what a white light solar filter can show.

Phenomena such as solar protuberances, active spots, flares, granulations, plasma filaments and more finally become observable and photographable with excellent sharpness and resolution. Hydrogen Alpha (Ha) solar telescopes are specialized instruments for observing the Sun at a specific wavelength of light, 656.3 nm, corresponding to the red line of the Balmer series in the hydrogen emission spectrum. This wavelength is critical for studying solar phenomena such as protuberances, filaments, sunspots and flares.

Unlike standard white-light telescopes, which capture the full solar spectrum, Ha telescopes offer a specific window into the activities of the chromosphere, the layer of the solar atmosphere located just above the photosphere. Compact and Portable: The metal optical tube makes the Acuter Phoenix 40mm solar telescope ideal for travel, while the rugged design ensures uncompromising durability.

Perfect for experienced observers and enthusiasts who wish to explore and admire the Sun's surface in detail. Perfect for astrophotography enthusiasts and observers of the Sun.

It is recommended in combination with the Sky-Watcher SUNGT mount for a portable and automated setup capable of automatically framing and tracking the Sun.

ISO Certified Safety: This telescope complies with ISO 12312-2:2015, ensuring maximum protection for the eye during solar observation.
