Lunt 100mm Universal Day & Night Telescope

• Preorder notice: ships 60–90 days after checkout (estimated window)

• One rig for everything: H-alpha, CaK, white light, lunar/planetary, deep-sky, and terrestrial—switch modules, not telescopes

• 100 mm professional-grade APO triplet (FPL53) with Ion-Assist broadband AR coatings for tack-sharp contrast day and night

• Modular H-alpha system (656.28 nm) starts at <0.65 Å single-stack; add a double-stack later to tighten to <0.45 Å when you want surface detail to really pop

• Doppler True barometric pressure tuning gives instant, precise on-band control—track filaments from base to tip like a pro

• f/7, 714 mm focal length balances full-disk views, high-res detail, and flexible nighttime imaging

• Choose your fit: Blocking Filter (12/18/34 mm; diagonal or straight-through) and Focuser (dual-speed Rack & Pinion or dual-speed Feather Touch) to match your workflow

• Red Dot Sun Finder handle for fast, confident solar alignment; CNC rings + Vixen-style dovetail for easy mounting

• Built to travel: aluminum hard case with fitted foam protects the optics between sessions

• Theoretical max magnification: ~175× on steady nights
