The LS100MT represents the pinnacle of Lunt’s modular telescope design. The 100mm f/7 ED triplet objective uses premium FPL53 glass with ion-assisted broadband AR coatings, delivering exceptional color correction and contrast. The internal pressure-tuned etalon achieves <0.65Å bandpass through Doppler True Barometric Pressure Tuning, and the modular design allows complete removal of the H-alpha system for nighttime deep-sky observation. Two telescopes in one, with no compromise in either mode.

This imaging-focused package pairs the LS100MT with the B1800 blocking filter, providing an 18mm clear aperture that fully illuminates full-frame sensors without vignetting. The complete four-eyepiece flat-field set covers every visual magnification from full-disk surveys to high-power active region detail.

What You’ll See

By day: the hydrogen-alpha chromosphere at a level of detail that only 100mm of premium optics can deliver. The FPL53 triplet provides the color correction and contrast that brings out the finest chromospheric structure. Prominences with internal threading and flow detail. Filaments with multi-strand complexity. Active regions with the full depth of their magnetic architecture revealed. Four eyepieces cover every target and condition. The 8mm (approximately 100x on the LS100MT) pushes resolution to the limit when seeing cooperates. The 12mm and 16mm provide the working magnifications for detailed surface observation. The 19mm pulls back for full-disk context and prominence surveys. All four share consistent 60° apparent fields and 0.1% AR coatings.

By night: remove the H-alpha module and you have a premium 100mm f/7 ED triplet refractor. The same FPL53 glass and ion-assisted coatings deliver exceptional lunar, planetary, and deep-sky performance. The same focuser, the same mount, the same optical quality.

Why This Package

The LS100MT is a different class of instrument from the LS100. Premium FPL53 ED triplet optics. Modular day/night design. The color correction and contrast that serious observers and imagers demand. If you are investing in 100mm of aperture, this is the optical system that does it justice. The B1800 blocking filter with 18mm clear aperture is purpose-matched to this telescope’s imaging potential. Full-frame sensor coverage without vignetting, combined with ZWO EAF-compatible focuser for motorized control during imaging sessions. Four dedicated eyepieces ensure the visual experience matches the optical quality.
