Lunt LS100FHa H-alpha double-stack Solar Filter

1. Advanced Double Stacking: The LS100FHa filter utilizes a dual etalon system to achieve an exceptionally narrow bandwidth of <0.55 Angstrom. This highly refined filtration allows observers to discern intricate details on the Sun's surface and prominences with enhanced contrast and clarity, surpassing what single etalon systems can offer.

2. Precision H-alpha Observation: Designed specifically for dedicated H-alpha solar observation, this filter isolates the hydrogen-alpha light spectrum at 656.28 nm, crucial for viewing solar flares, granulation, and other dynamic phenomena in high resolution. Its precise engineering ensures crisp, detailed views for both amateur and professional astronomers.

3. Tiltable Etalon Tuning: Equipped with a tiltable etalon, the filter provides precise control over the filter's bandpass. This crucial feature allows users to fine-tune the filter's performance to compensate for Doppler shift caused by solar activity or the observer's motion, ensuring optimal contrast and visibility of specific solar features.

4. Robust Construction: Crafted with high-quality materials and precision machining, the LS100FHa filter boasts a robust and durable construction. This ensures long-term stability and reliability even with frequent use, protecting the sensitive optical components and maintaining consistent performance over its lifespan.

ABOUT THE Lunt LS100FHa H-alpha double-stack Solar Filter

The Lunt LS100FHa H-alpha double-stack Solar Filter stands out in the realm of solar observation due to its exceptional double-stacked etalon system, which narrows the bandwidth to an impressive <0.55 Angstrom. This is a significant improvement over single-stacked filters, providing unparalleled contrast and resolution for observing the Sun's intricate details, such as prominences, filaments, and surface granulation. Designed for serious solar enthusiasts and researchers, its primary use is dedicated H-alpha viewing, allowing for the precise isolation of hydrogen-alpha light. The inclusion of a tiltable etalon mechanism further enhances its versatility, enabling users to fine-tune the bandpass for optimal viewing conditions, accounting for various solar phenomena. The precision mechanics ensure a stable and consistent performance, revealing features that are often invisible with less specialized equipment. To maintain its superior performance and extend the product's lifetime, the use of original Lunt Solar Systems accessories and spare parts is highly recommended.
