Lunt LS100MT Enhanced Kit - 100mm Universal Day & Night Modular Telescope

LS100MT Enhanced Kit — 100mm Universal Day & Night Modular Telescope Premium FPL53 ED triplet optics. Full imaging capability. Four eyepieces. Two telescopes in one.

Now with new-generation etalons — every unit individually tested on Lunt's precision metrology equipment. Every specification is verified, not estimated.

The LS100MT Enhanced Kit represents the pinnacle of Lunt's modular telescope design. The 100mm f/7 FPL53 ED triplet objective with ion-assisted broadband AR coatings delivers exceptional colour correction and contrast in both solar and nighttime modes. The internal pressure-tuned etalon delivers 0.45Å verified 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 18mm of clear aperture that fully illuminates full-frame sensors without vignetting, alongside a complete four-eyepiece flat-field set covering 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 brings out the finest chromospheric structure with the colour correction and contrast that serious observers demand. 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 (~87x 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 FPL53 ED triplet refractor. The same glass, the same ion-assisted coatings, the same focuser, the same mount — delivering exceptional lunar, planetary, and deep-sky performance.

Why This Package

The LS100MT is a different class of instrument. Premium FPL53 ED triplet optics. Modular day/night design. 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 motorised control during imaging sessions. Four dedicated eyepieces ensure the visual experience matches the optical quality. And like all Lunt 100mm systems, the Enhanced is fully double-stack capable — add the SFPT module at any time to bring combined system bandpass to <0.28Å.
