Lunt LS60FHa/d1 H-alpha solar filter

1. Unobstructed Aperture: The 60 mm clear aperture design ensures maximum light collection and uniform illumination across the solar disk, providing superior image quality without typical central obstructions.

2. Narrow Bandwidth: With a bandwidth of less than 0.75 Angstroms, this filter allows for incredibly detailed observation of the Sun's chromosphere, making active regions, prominences, and filaments stand out with high contrast.

3. Tilt Etalon Tuning: The integrated tiltable etalon allows for fine-tuning of the H-alpha wavelength, providing observers the ability to optimize contrast and selectively view different layers of the solar atmosphere.

4. Dedicated Solar Observation: This H-alpha filter is specifically engineered for dedicated solar viewing, offering specialized performance that standard white-light filters cannot match, revealing the dynamic nature of our star.
