Lunt LS130MT Modular H-Alpha Solar Telescope
Lunt LS130MT 130 mm H-Alpha Solar Telescope
A complete refractor-based solar telescope system, this 130 mm aperture LS130MT with 910 mm focal length (f/7) from Lunt Solar features a precision-aligned triplet ED apochromatic lens made of Ohara FPL51 glass. Perhaps the most crucial aspect of the LS130MT is the <0.65 Angstrom bandpass enabled by an internal etalon with tune adjustment.
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.
Solar Blocking Filter Options
Please Note - You must have a Lunt blocking filter to view the Sun safely with this OTA! Please choose a blocking filter from the drop-down above or, if you already have a blocking filter, you can choose just the No Blocking Filter option. Thank you.
Read below for further information on the blocking filter options.
B1200 Blocking Filter for use with the LS130MT
The B1200 blocking filter is the most economical choice and is recommended for those who only plan to do visual observations (no imaging). You will have the best results with the 12 mm blocking filter if your mount has auto-tracking. For manual tracking, we recommend the B1800, with it's wider field of view. The BF1200 will come in a 2" diagonal housing.
B1800 Blocking Filter for use with the LS130MT
The 18 mm blocking filter is recommended for anyone who wishes to do imaging, will be tracking the Sun manually, or just wants more sky area round the Solar disk. The B1800 will come in a 2" diagonal housing that has T2 connections for mounting a camera or other T2 accessory.
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.
