Lunt LS130MT Telescope

The LS130MT is built to be reconfigured. You can remove the solar etalon unit from the optical train to convert the telescope from a dedicated solar instrument into a standard APO triplet refractor for nighttime viewing, allowing you to use the same high-quality glass for two different types of astronomy.

Because of the 130mm aperture and the pressure-tuned etalon, you will get high-contrast views of solar features like prominences, filaments, and sunspots. The pressure-tuning system allows you to precisely adjust the etalon to bring out subtle surface details that fixed-filter systems often miss.

Yes, the FPL51 ED triplet optics are designed to minimize chromatic aberration, making it a strong candidate for astrophotography. However, keep in mind that you will need to provide your own camera adapters and field flatteners to optimize the image circle for your specific sensor.

The telescope itself is substantial due to the 130mm aperture and triplet lens design. You will need a sturdy equatorial or heavy-duty alt-azimuth mount capable of handling the weight of a large refractor to ensure stable viewing and tracking, especially for high-magnification solar work.

The B1800 blocking filter is well-suited for the 910mm focal length of this telescope. It provides a generous field of view that allows you to see the entire solar disk, which is ideal for both visual observation and imaging.

The dual-speed focuser is essential for precision. The coarse knob gets you into focus quickly, while the fine-focus knob allows for the micro-adjustments needed to snap solar features or planetary details into sharp focus, which is critical when working at higher magnifications.
