Lunt LS130MT Solar Telescope ST 130/910 Ha B3400 R&P Allround OTA

Full 130 mm ED apochromatic telescope, an H-alpha solar telescope during the day

The Lunt LS130MT It's not a solar telescope with a night mode as an afterthought. It's a fully-fledged 130mm f/7 ED apochromat with an FPL-51 triplet objective, for which Lunt adds an H-alpha module. During the day, you observe the sun in H-alpha; in the evening, you remove the etalon unit, mount the supplied extension tube, and you have a serious APO for deep-sky and planets.

130 mm opening: resolution rarely seen on the sun

With a 130 mm unobstructed aperture, you achieve a resolution on the sun that virtually no other H-alpha telescope in this segment offers: layered prominences, fine fibrils, plage structure, and active regions down to the granulation level. The internal etalon with a bandwidth of less than 0.7 Ångström is tuned with the Pressure-Tuner: uniform from edge to edge, with no wear.

B3400-blockfilter: the maximum field of view

In this version, the B3400 block filter with a 34mm aperture is permanently integrated into the 2-inch focuser. This allows the LS130MT to fully illuminate even large camera sensors: full-disk solar photography with maximum detail, without vignetting. This is the version for the solar photographer who wants no compromise on the image frame.

Expandable system

The LS130MT is the heart of a modular platform. With the DSII Double-Stack module, you can further reduce bandwidth for maximum surface contrast, and with the Ca-K filter module, you can observe the sun in the calcium line. Both modules can be found below as additions. At night, with the extension tube, the telescope is a 130 mm f/7 triplet for visual use and astrophotography.

Specifications

An H-alpha solar telescope is safe for solar observation due to its closed filter system. Check the etalon and blocking filter for damage before each use. Never look at the sun through an ordinary telescope, binoculars, or finder without a certified solar filter on the objective end.
