Lunt 130mm Universal Day & Night Telescope

Observer Package

• Versatile day-to-night system: swap from H-alpha solar views to nighttime astronomy in just minutes—no fuss, no compromises

• 130 mm triplet ED APO (Ohara FPL51) delivers crisp, high-contrast imaging for solar detail by day and planets/deep-sky by night

• Internal etalon with True Doppler pressure tuning lets you sweep features on-band for that 3D-like pop in filaments and active regions

• Visual-first package includes a B1200 blocking filter—ideal full-disk visual performance with room to grow

• 2" dual-speed rack & pinion focuser (10:1) provides precise, repeatable focus for both eyepieces and cameras

• <0.65 Å bandpass (single stack) out of the box; add the optional LFPT internal double-stack module later to tighten to <0.45 Å

• White-light ready: included 2" wedge + polarizer for high-contrast photosphere observing (sunspots, faculae, granulation)

• Field-friendly build with cradle ring and built-in red-dot solar finder, 10" Vixen-style dovetail, and aluminum hard case for travel

• A true “one-telescope” solution for solar outreach, imaging practice, and nighttime sessions—all under a 5-year Lunt warranty
