Acuter, a brand recognized worldwide for its innovative, high-quality astronomical instruments, presents the Luma-X 40ED : a revolutionary solar telescope that sets new standards for performance, versatility, and affordability. Designed for both passionate amateur astronomers and educational use, this instrument opens the door to detailed and safe observation of our star.
The Luma-X 40ED boasts two daring world firsts:
| Innovation | Benefit for the observer |
|---|---|
| Square tube - exclusive design | Rigid, compact and original structure for easy transport |
| Switchable angled return - dual use | Instantly switch between H-Alpha (protuberances) and the white light (sunspots) without changing accessories |
Equipped with a ED (Extra-low Dispersion) glass element, The Luma-X 40ED offers outstanding sharpness, contrast and color fidelity. The fine details of the solar surface - granulation, spicules, filaments - are rendered with impressive precision.
Thanks to its 40 mm front gauge with a bandwidth of less than 0.6 Ångström and its 8 mm blocking filter integrated into the angled reflector, you can observe spectacular solar phenomena in real time: flares, protuberances, spicules, sunspots and much more. All in compliance with safety standards ISO 12312-2:2015.

For automatic sun tracking, the mount Sky-Watcher SolarQuest Go-To/Tracking is highly recommended (sold separately). It provides precise motorized pointing and tracking, making it ideal for extended observation and solar astrophotography.
Observing the Sun carries serious risks. Inappropriate use can lead to irreversible eye damage. The 8 mm blocking filter integrated into the angled transmission is an integral part of the Luma-X 40ED's safety system. Never use another elbow joint for observing the Sun with this instrument. Carefully follow the instructions in the user manual.
