152mm Pressure-Tuned w/ B3400

The Lunt 152mm Pressure-Tuned is the largest dedicated hydrogen-alpha solar telescope currently available, engineered for intermediate to advanced solar observers and astrophotographers seeking professional-grade performance. This refractor-based system features an unobstructed internal HD etalon with innovative Doppler True Pressure Tuning technology, delivering a narrow bandpass of less than 0.65 Angstroms at 656.28nm for exceptional chromospheric detail. The 100% unobstructed optical design combined with advanced high-contrast coatings provides crisp, sharp views at both low and high magnifications, while True Doppler Tuning adds a unique 3D-like component to the viewing experience, allowing dynamic shifts through solar filaments and active regions. Ideal for both visual observation and high-end imaging with larger CCD sensors using the B3400 straight-through blocking filter.
