Acuter Elite Phoenix 40 H-alpha solar telescope

Experience the sun in H-alpha with the Acuter Elite Phoenix 40

The Acuter Elite Phoenix 40 takes solar observation to a professional level. Where a standard solar telescope limited to white light (sunspots), this H-alpha telescope shows the dynamic chromosphere of the sun. With an aperture of 40mm and an impressive bandwidth of 0.6 ångström or better, enjoy a high-contrast image full of activity.

Unprecedented details: from prominences to spicules

Thanks to the precise pressure tuning (pressure control) you tune the telescope exactly to the H-alpha line. This reveals breathtaking phenomena that are hidden by the naked eye or normal filters:

• Protuberances: Giant gas loops shooting out of the solar surface.
• Solar flares: Powerful bursts of energy.
• Surface details: Granulation and fine structures around sunspots.

Safety and versatility

Safety is at this solar telescope guaranteed by the front-mounted etalon and the 8mm blocking filter in the diagonal. The instrument fully complies with the ISO 12312-2:2015 norm. Unique to the Phoenix 40 is its modularity: remove the etalon and solar diagonal, and you're left with a high-quality 80/400 achromatic refractor for nighttime observations.

“The detail through the narrow bandwidth and the amazing contrast across the entire solar disk are fascinating. It is one of the best H-alpha images I have seen.” - Astronomy Now Magazine
