Lunt 130 mm Modular H-Alpha Solar Telescope Advanced Package with B1800 Blocking Filter

Optimally suited for imaging applications, the B1800 Blocking Filter included in this Lunt Solar LS130MT H-Alpha Solar Telescope Advanced Package also provides a larger field of view compared to the B1200. A 2” white light wedge, calcium wedge, 2” diagonal, 27 mm and zoom eyepieces, polarizing filter, and dovetail are also included in this package to go with the B1800.

This Lunt 130 mm f/7 LS130MT H-Alpha Solar Telescope incorporates a precision-aligned triplet ED apochromatic lens consisting of Ohara FPL51 glass. Based on refractor-style optics, the LS130MT is a complete solar telescope system with 910 mm of focal length. In order to achieve high precision focusing, a 2” Starlight Feather Touch Focuser with 10:1 reduction is included as standard equipment. A slide tube is used to make coarse focus adjustments. The LS130MT's most significant feature, however, is its internal etalon with tune adjustment that allows for a <0.65 Angstrom bandpass.

With the Lunt LS130MT, you can easily switch between viewing the Sun during the day to viewing planets and other celestial objects at night, providing excellent versatility in only a few minutes! Adapts well to either viewing condition with etalons used for solar observing removed for night sky observing. Granular details of the solar surface will present themselves like you’ve never seen, while views of the night sky will be void of visual anomalies. Now all your celestial viewing can be done using only a single telescope.

True Doppler Tuning

True Doppler Tuning primarily allows for a shift into and away from the user, adding a 3-D like component to the viewing experience. Although the effect this has on prominences is minimal due to their location at the edge of the disk, it does have an impact on filaments and similarly active regions on the surface. Additionally, while looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip, thus following the filament through its structure toward you and away from you. This enhanced visual and imaging capability benefits the observer while providing a useful research tool for the avid hobbyist. Lastly, the LS130MT’s pressure tuning system allows for more precise tuning of desired features by an order of magnitude.

Optional Internal Double Stacking Module

While the Lunt LS130MT comes standard as a single-stacked system with a <0.65 Angstrom bandpass, you can have this reduced to <0.45 Angstroms with the help of an internal double stack module (not included). This enables high definition solar views with truly enhanced surface details that seem as if they are "popping out" at you. This does not require that the LS130MT be returned to the factory. In fact, purchasing the single-stacked version provides a more affordable way to obtain Lunt’s best solar scope while still leaving room for upgrades at a later date. However, if you do decide on the LFPT internal double stack module upgrade, you’ll be able to experience our closest star in finer detail than ever before.
