Visit Acuter Elite Phoenix 40 is a new-generation solar telescope designed to observe our star in stunning detail. Thanks to a 40 mm H-alpha standard at the front and an integrated blocking filter, it reveals the Sun's most dynamic structures: protuberances, filaments, flares and active patches appear in high definition in intense red light, filtered around 656 nm. With a bandwidth of less than 0.6 Ångström, this telescope rivals much more expensive instruments.
But the Phoenix 40 doesn't stop there: with just a few flicks of the wrist, it can also become a classic 80 mm f/5 refractor for deep-sky and planetary observation. This rare versatility makes it the ideal two-in-one instrument for curious astronomers, educators or experienced amateurs.

The Phoenix 40 is one of the few telescopes capable of transformation. By simply removing the standard and the solar bent reflector, then installing the classic diagonal mirror supplied, it becomes a true refractor 80/400. Ideal for nebulae, open clusters, the Moon or Jupiter, it can be used with standard 1.25″ eyepieces and can accommodate short CCD or CMOS cameras (55 mm backfocus or less).
Thanks to its ISO-compliant design, integrated solar finder and blocking filter, the Phoenix 40 guarantees maximum safety during H-alpha observations. However, it is crucial to always use the telescope with the original components supplied (in particular, the solar bent reflector) and never to point it at the Sun without these protections.
Supplied with a universal smartphone adapter, it makes it easy to capture spectacular images of the solar chromosphere. It is also compatible with 1.25″ astronomical cameras for professional results. Generous backfocusing makes it easy to focus, even with more complex systems including Barlow or filter wheel.
Visit Acuter Elite Phoenix 40 is much more than a solar telescope: it's an evolutionary, compact and affordable observation platform. High-performance in H-alpha, versatile in night mode, it is a unique solution for exploring the Sun... and the stars. An ideal instrument for schools, astronomy clubs, curious enthusiasts and lovers of beautiful images.
