Acuter Luma-X 40ED - H-Alpha & white light solar telescope with ED optics<\/h3>\n

Acuter<\/strong>, the world-renowned brand for innovative, high-quality astronomical instruments, presents the Luma-X 40ED<\/strong>\u00a0a revolutionary solar telescope that redefines standards in terms of performance, versatility and accessibility. Designed for both amateur and educational use, this instrument opens the door to detailed observation of our star in complete safety.<\/p>\n

Exclusive worldwide innovations<\/h3>\n

The Luma-X 40ED boasts two daring world firsts:<\/p>\n\n\n\n\n\n\n
Innovation<\/th>\nAdvantage for the observer<\/th>\n<\/tr>\n<\/thead>\n
Square tube<\/strong> - exclusive design<\/td>\nRigid, compact and original structure for easy transport<\/td>\n<\/tr>\n
Switchable angled return<\/strong> - dual use<\/td>\nInstantly switch between H-Alpha<\/em> (protuberances) and the white light<\/em> (sunspots) without changing accessories<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

High-resolution ED optics<\/h3>\n

Equipped with a ED (Extra-low Dispersion) glass element<\/strong>, 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.<\/p>\n

Safe H-Alpha observation<\/h3>\n

Thanks to its 40 mm front gauge<\/strong> with a bandwidth of less than 0.6 \u00c5ngstr\u00f6m<\/strong> and its 8 mm blocking filter<\/strong> 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<\/strong>.<\/p>\n

Recommended installation<\/h3>\n

For automatic sun tracking, the mount Sky-Watcher SolarQuest Go-To\/Tracking<\/strong> is highly recommended (sold separately). It provides precise motorized pointing and tracking, ideal for extended observation and solar astrophotography.<\/p>\n

\u26a0 Safety warning<\/h3>\n

Observing the Sun involves serious risks.<\/strong> Inappropriate use can lead to irreversible eye damage<\/strong>. The 8 mm blocking filter integrated into the angled transmission is an integral part of the Luma-X 40ED's safety system. Never use any other angle drive<\/strong> for solar observation with this instrument. Strictly follow the instructions in the user manual.<\/p>","protected":false},"excerpt":{"rendered":"
