Lunt 152mm Ha Telescope

• Preorder notice: ships ~6 months after checkout (estimated delivery window)

• Big-aperture 152 mm f/6 dedicated H-alpha refractor for jaw-dropping full-disk views and ultra-crisp detail on prominences, filaments, plages, and granulation

• True Doppler Pressure Tuning lets you “walk” features across the disk for a dynamic, 3D-like perspective and repeatable on-band performance

• Single HD etalon <0.65 Å @ 656 nm balances high surface contrast with clean limb detail—excellent for serious visual and entry-to-pro imaging

• Blocking filter required for safe operation—choose the package that fits your workflow: B1200 (visual), B1800 (larger FOV/imaging), or B3400 (largest FOV/large sensors); “No Blocking Filter” only if you already own a compatible Lunt BF

• 2" rack-and-pinion focuser provides smooth, precise focusing with heavy eyepieces or cameras

• 100% unobstructed refractor design with advanced high-contrast coatings maximizes throughput and sharpness at low and high power

• Ready to accessorize: compatible with Sol-Searcher, a range of eyepieces, and common dovetail options

• Expand your science: optional interchangeable CaK module adds multi-wavelength flexibility; night-time conversion available via backing plate & focuser kit

• Field-ready package includes rings, dovetail, dust caps, and a rugged aluminum reinforced case—built for the intermediate to advanced solar observer
