Lunt Front Mount Double Stack: Push Your Solar Observing Beyond a Single Stack!
Unlock H-alpha solar views with the Lunt Solar Systems LS60FHa front-mounted solar filter! Designed to transform your existing refractor into a high-performance solar telescope, this 60 mm tilt-tuned etalon delivers stunning full-disk and close-up views of the Sun with razor-sharp contrast and incredible detail. Watch prominences, dark filaments, active regions, and delicate surface texture come alive in H-alpha detail through a verified 0.35Ã… bandpass system. Want even more contrast? Pair the LS60FHa with an existing Lunt H-alpha system for double-stack performance, narrowing the combined bandpass to an ultra-high-contrast <0.28Ã… for dramatically enhanced surface detail and darker backgrounds.
Installation is fast and simple. The LS60FHa mounts directly to the front of your compatible refractor using the proper adapter, and removes in seconds when you're ready to switch back to nighttime observing. One telescope becomes both a premium solar instrument by day and a traditional refractor by night—no permanent modifications required. With its unobstructed 60 mm aperture and edge-to-edge optical performance, the LS60FHa is an easy way to experience the Sun like never before while getting even more versatility out of the telescope you already own.
Already own a compatible ED refractor?
The LS60FHa retrofits a compatible customer-supplied ED refractor for daytime solar observation and is easily removed for night use. A Lunt blocking filter must be used at all times — this is a safety requirement. Select the correct blocking filter for your telescope and intended use (sold seperately):
- B600 — up to 540mm focal length, 1.25" or 2" diagonal
- B1200 — up to 1,080mm focal length, 1.25" or 2" diagonal
- B1800 — up to 1,620mm focal length, 1.25" or 2" diagonal
- B3400 — up to 3,060mm focal length, 2" straight-through tube
Specifications
- Optical Aperture: 60mm — no central obstruction
- Tuning: Tilt-tuned
- Single Etalon Bandpass: 0.35Å — individually verified
- DS Combined Bandpass: <0.28Å — when paired with a second etalon in series
- Compatible: Lunt LS60THA and LS60MT; compatible customer ED refractors
- Blocking Filter Required: Yes B600 (visual) & B1200 (imaging); (sold separately)
- Weight: 3 lb (1.5 kg)
