Lunt Solar LS80MT Optical Tube Assembly

The LS80MT features a modular design that allows you to remove the H-alpha etalon and blocking filter assembly. Once these solar components are detached, the unit functions as a standard 80mm f/7 refractor, making it suitable for observing the moon, planets, and brighter deep-sky objects.

Pressure tuning allows for a more precise and uniform adjustment of the filter's bandpass across the entire field of view. This results in higher contrast and better detail when observing solar features like filaments and prominences compared to traditional tilt-tuning systems.

Yes, the package includes the B1800 blocking filter, which is essential for safe solar viewing. You will still need to provide your own eyepieces and a compatible mount to support the 9.25-pound optical tube.

Yes, the dual-speed mechanism provides both coarse and fine focus adjustments, which is critical for achieving sharp focus when imaging the sun or night-sky targets. Its robust construction is designed to handle the weight of standard cameras without slipping.

The transition is straightforward and requires no specialized tools. You simply unscrew the solar modules from the optical tube and replace them with the necessary adapters for your night-sky diagonal or camera, making it a practical choice for observers who want one telescope for all conditions.

Because the LS80MT weighs 9.25 pounds, you will need a sturdy alt-azimuth or equatorial mount capable of handling that payload. Ensure your mount has a compatible saddle to accept the included clamshell mounting ring.
