Lunt 152mm H-Alpha Telescope with B3400

• Observatory-class 152 mm f/6 dedicated H-alpha refractor built for crisp full-disk views and razor-detail close-ups

• 100% unobstructed internal HD etalon with True Doppler Pressure Tuning for precise, repeatable on-band performance and that 3D-like perspective on filaments and active regions

• Bandpass <0.65 Å @ 656 nm: high contrast on surface texture, plages, filaments, and dramatic limb prominences

• Includes the B3400 blocking filter (internal mount) for larger field of view and big-sensor imaging headroom; star diagonal required for visual use

• Premium 2" Starlight Feather Touch focuser handles heavy accessories with silky, backlash-free control

• Intermediate to advanced user sweet spot: stable tuning, high throughput, and serious imaging capability

• Mod-friendly platform: optional interchangeable CaK module adds multi-wavelength flexibility; optional backing plate & focuser kit lets you convert for nighttime observing

• Ships ready to roll with mounting rings, dovetail, Lunt Zoom Eyepiece, dust caps, and a travel-tough aluminum case

• Elegant Pearl White with Black & Red accents finish looks as good as it performs

• Reminder: All Lunt telescopes require a blocking filter—the B3400 is included with this package
