Lunt Solar Systems has recently upgraded this telescope with a new 0.4Å etalon (standard), delivering even higher contrast and finer solar detail than previous versions. All orders will ship with this latest, improved configuration—no action needed!
Please note: Lunt scopes with 34mm blocking filters do not include any diagonal (for solar, terrestrial, or nighttime use). You will have to provide your own standard diagonal to use this telescope for any application.
- Full 100mm H-alpha aperture reveals stunning prominences, filaments, active regions, and rich solar surface texture
- Quickly converts from a H-Alpha solar telescope to a nighttime Triplet ED APO refractor
- Precision Doppler True pressure tuning allows fine adjustment for maximum contrast and enhanced visibility of subtle solar features
- Optional internal double-stack filter available for ultra-narrow <0.28Å (sold separately)
Lunt Universal Day & Night Solar Telescope: Brighter Prominences and Darker Skies!
By day, the Lunt Solar Systems LS100MT operates as an H-alpha solar powerhouse, utilizing a premium 100 mm FPL51/FPL53 ED Triplet optical system with ion-assisted broadband AR coatings. This reference-grade glass works in tandem with an internal pressure-tuned etalon to deliver a verified, uniform <0.4Å bandpass across the entire aperture, resolving finer prominence structures, sharper filament definition, and pristine chromospheric detail. Equipped with a generous B3400 blocking filter to fully illuminate full-frame imaging sensors without vignetting, the system features a ZWO EAF-compatible dual-speed focuser built for serious imaging and visual observation. The modular design allows you to add a DS100 double-stack module at any time ( sold seperately ) to drop the combined bandpass to an industry-leading <0.28Å.
When the sun sets, the LS100MT easily transitions into one of the finest 100 mm f/7 nighttime triplet refractors available by simply removing the H-alpha module and installing the night-sky backing plate. Because it is built around reference-grade FPL53 ED triplet optics rather than a standard doublet, it eliminates chromatic aberration to deliver exceptional color correction, contrast, and resolution across the night sky. Whether you are hunting for faint deep-sky nebulae, imaging distant galaxies, or observing crisp planetary detail, this telescope applies its world-class mechanical and optical quality to everything the night sky has to offer without requiring a second instrument.
True Doppler Tuning.
At the heart of the system is Lunt’s precision Doppler True pressure tuning technology, allowing you to make fine adjustments to the etalon for optimal contrast and visibility of different solar features. The upgraded etalon system enhances the viewing experience even further, bringing out more structure and subtle detail across the solar disk.
