Lunt Solar LS100MT

Yes, the LS100MT is designed as a modular system. You can remove the solar etalon modules to convert the 100mm FPL53 ED triplet into a high-performance refractor for lunar, planetary, and deep-sky observation.

The dual pressure-tuned system allows you to independently adjust the etalons to achieve a bandpass of less than 0.28Å. This precision is critical for isolating specific chromospheric details, giving you much higher contrast on solar prominences and surface features than a single-stack system.

The B1800 blocking filter features an 18mm clear aperture, which is well-suited for full-frame sensor imaging. It provides a sufficiently large illuminated field to minimize vignetting when capturing solar details.

While the telescope includes an 8-inch Vixen-style dovetail for mounting, it does not come with a tripod or mount. Because it is a 100mm refractor, you will need a sturdy equatorial or alt-azimuth mount capable of handling the weight and length of the optical tube for stable viewing.

The 2-inch rack-and-pinion focuser includes a 10:1 reduction knob, which is essential for achieving critical focus. This level of control is particularly helpful when imaging the sun or observing fine planetary details where focus sensitivity is high.

Yes, the focuser is compatible with the ZWO EAF, allowing you to automate your focusing process. This is a significant advantage for solar imaging, where focus can shift slightly due to thermal changes during the day.
