Description
Lunt 100mm LS100MT/B3400R&P Universal OTA – Day & Night Precision
The LS100MT/B3400 is a multi-purpose, modular telescope designed for both H-alpha solar observation and nighttime astronomy. Its innovative design allows for effortless conversion between these applications with just a few simple adjustments. This 100mm FPL-53 triplet apochromatic refractor delivers exceptional image quality, ensuring sharp and detailed views whether you’re observing the Sun’s dynamic surface or exploring deep-sky wonders after dark. Equipped with an advanced air pressure tuning system, a precision-engineered 2-inch rack & pinion (R&P) focuser, and a B3400 blocking filter, this telescope offers premium performance for both visual and imaging applications.
H-alpha Solar Observation
The LS100MT/B3400 is a complete H-alpha telescope with a 100mm unobstructed aperture and 714mm focal length, optimized for high-resolution solar viewing. The H-alpha wavelength (656.28 nm) reveals incredible solar phenomena, including prominences, filaments, and surface flares, offering a breathtaking view of our Sun. Its internal Etalon filter achieves a bandwidth of <0.7 Ångström, utilizing the Pressure-Tuner system for precise spectral tuning. By adjusting the air pressure inside the telescope, users can fine-tune their view of solar features with enhanced contrast and clarity. This system ensures a homogeneous field of view, free from central obstructions, and provides long-term protection for the Etalon filter.
For fine focus control, the LS100MT/B3400 is equipped with a robust 2-inch R&P focuser with 10:1 micro-adjustment, allowing smooth and precise focusing. The B3400 blocking filter, permanently housed within the focuser, supports both high-resolution solar imaging (ideal for large sensor cameras) and visual observations. The standard 2-inch accessory compatibility makes it easy to integrate additional components such as star diagonals.
Night Sky Observation
Thanks to its modular design, the H-alpha Etalon system can be removed in just a few simple steps, transforming the LS100MT into a high-performance apochromatic refractor for nighttime observing and astrophotography. When paired with the optional conversion kit, the telescope functions as a standard 100mm f/7 ED triplet, perfect for viewing planets, the Moon, and deep-sky objects. Its FPL-53 optics deliver outstanding color correction and sharpness, ensuring vivid, high-contrast images across the entire visible spectrum.
Expanded Functionality with Optional Accessories
The LS100MT offers even greater versatility with additional upgrade options:
- Double-Stack for Enhanced H-alpha Viewing: The telescope can be upgraded with the DSII/SFPT double-stack module, reducing the bandwidth to <0.5 Ångström, significantly increasing surface contrast and revealing even more fine solar details.
- White-Light Solar Observation: After removing the H-alpha unit, users can observe sunspots and solar granulation using either a front-mounted solar filter or a Herschel wedge at the focuser.
- Calcium-K (Ca-K) Solar Observing: The LS100MT is also compatible with Lunt’s Ca-K modules, allowing detailed imaging of solar features in the Ca-K wavelength (393.4 nm), which highlights supergranulation patterns and chromospheric structures.
A Premium, All-in-One Apochromatic Telescope
With its exceptional modular design, premium optics, and extensive upgrade options, the LS100MT/B3400 is a truly universal telescope, offering top-tier performance for both solar and deep-sky astronomy. Whether you’re capturing intricate solar features in H-alpha or exploring the cosmos at night, this telescope delivers an unparalleled observing experience.
SOLAR WARNING
- Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
- Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
- Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
