Acuter Elite Phoenix 40 H-Alpha Solar Telescope

Experience the Sun in extraordinary detail.

The Acuter Elite Phoenix 40 H-Alpha Solar Telescope delivers breathtaking views of the Sun’s dynamic surface, offering an impressive level of performance, safety, and precision at its price point. Designed for both amateur astronomers and educational use, this advanced solar telescope reveals stunning solar phenomena such as prominences, flares, filaments, and sunspots in real time — safely and clearly.

Professional H-Alpha Solar Observation

Featuring a 40mm front-mounted Etalon with a bandwidth of <0.6 Ångström, the Elite Phoenix 40 isolates the H-alpha wavelength to display intricate solar activity in remarkable detail. Its pressure-tuned system allows precise adjustment for optimal contrast, while the 8mm blocking filter ensures complete user safety when viewing the Sun.

The telescope meets all safety standards under ISO 12312-2:2015, providing peace of mind during every observation session.

Versatile Dual-Use Design

With the Etalon and solar diagonal removed, the telescope converts into a high-quality 80mm f/5 achromatic refractor, ideal for night-time astronomical observation. This dual-purpose versatility makes the Phoenix 40 a perfect all-round instrument for year-round stargazing.

Capture and Share Your Solar Discoveries
