Acuter LUMA-X 40ED H-Alpha solar telescope

 40mm ED F/6.25 Dual Purpose H-Alpha Prominence/White Light Sunspot Telescope

Acuter is a world-leading brand of innovative, high-quality products for amateur astronomy and educational use.

The revolutionary Acuter Luma-X 40ED represents a remarkable level of specification and performance at an affordable price. It features groundbreaking, world-first innovations such as a square telescope tube design and an exclusive switchable star diagonal, allowing you to switch from an H-alpha prominence telescope to a white light solar telescope for observing sunspots. The telescope incorporates an ED glass element, which enhances sharpness and contrast, as well as color fidelity and detail rendition.

The Acuter Luma-X 40ED is a safe solar telescope equipped with a 40mm front etalon with a bandwidth of 0.6 angstroms or better for observing active solar prominences and other solar surface details in the H-alpha band.

Observing the Sun in the narrow H-alpha band will reward you with stunning, breathtaking, and majestic real-time views of our nearest star, revealing magnificent details such as solar flares, prominences, spicules, granulation, sunspots, and more!

A universal smartphone camera adapter is included to capture your observations.

The Acuter Luma-X 40ED meets the transmission requirements of ISO 12312-2:2015 (filters for direct observation of the Sun). Always follow the instructions in the manual.

Safety Information:

Please exercise extreme caution when observing the Sun. Improper use can lead to serious and permanent eye damage!

The 8mm blocking filter in the removable star diagonal is part of the Luma-X 40ED's safety equipment. Never use the telescope with any other star diagonal for solar observation.
