Lunt LS100MT Kit Enhanced

LS100MT Enhanced Kit - Universal modular day & night telescope 100 mm H-Alpha

The LS100MT Enhanced Kit is the most advanced modular instrument in the Lunt range for solar and astronomical observation. Built around FPL53 ED triplet 100 mm f/7 with ion-assisted broadband anti-reflective treatments, it combines high-resolution H-alpha solar performance with uncompromising night-time astronomical capabilities.

Thanks to its modular architecture, the system allows the H-alpha module to be completely removed, transforming the LS100MT into a top-of-the-range triplet ED telescope for lunar, planetary and deep-sky observation. It's literally two telescopes in one.

The heart of the system is based on an internal standard Pressure-Tuned Doppler True offering a verified bandwidth of 0.45 Å and exceptional field uniformity across the entire 100 mm aperture.

FPL53 ED triplet 100 mm premium optics

The LS100MT Enhanced uses a lens FPL53 ED triplet 100 mm f/7, optimized for maximum color correction and high contrast.

Key benefits:

• Near-apochromatic color correction
• High contrast in sunlight and at night
• Excellent resolution at high aperture
• Optical stability with ion-assisted broadband AR coatings

This triplet design offers a higher level of performance than conventional doublets, particularly in high-resolution imaging.

H-Alpha Pressure-Tuned Doppler True system

The internal H-alpha system is based on a precision Pressure-Tuned standard:

• Bandwidth: 0.45 Å (individually verified)
• True Barometric Pressure Tuning Doppler technology
• Smooth adjustment without angular sweet spot effect
• Uniformity across the entire 100 mm field

The pressure setting allows you to explore different layers of the chromosphere in real time, with high spectral precision.

High-resolution solar observation 100 mm

With its 100mm aperture and triplet optics, the LS100MT Enhanced reveals an exceptional level of detail:

• Solar protuberances with complex internal structure
• Multi-stratate filaments with well-defined dark cores
• Detailed active regions with fine patches and structures
• Luminous bridges and visible penumbral structures
• Real-time dynamic training evolution

The combination of aperture and spectral precision enables observation close to the theoretical limit of resolution in the H-alpha range.

Premium night-time astronomy

Once the solar module is removed, the LS100MT becomes a high-end 100 mm f/7 triplet ED telescope:

• High-contrast lunar observation
• Detailed planetary observation
• Excellent color correction
• Wide-field deep-sky observation
• High performance on double stars

The same optical system is used for both modes, guaranteeing consistent quality day and night.

B1800 blocking filter and full-format imaging

The LS100MT Enhanced is equipped with the blocking filter B1800 :

• 18 mm clear aperture
• Complete coverage of full-format sensors
• No vignetting in the image field
• Optimization for high-resolution solar imaging

This filter is designed to fully exploit the imaging potential of the 100mm.

2″ motorized focusing system

The 2″ Rack & Pinion dual-speed eyepiece holder offers:

• 10:1 fine reduction for ultra-precise focusing
• High load capacity for heavy accessories
• ZWO EAF compatibility for motorization
• High mechanical stability for imaging

This system is indispensable for exploiting the resolution of the 100mm for solar and night-time imaging.

Complete set of 4 flat-field eyepieces

The LS100MT Enhanced includes a complete set of eyepieces:

• 8 mm (~87x) high-resolution observation of active regions
• 12 mm (~58x) versatile solar magnification
• 16 mm (~44x) balanced observation of extended structures

Common features :

• 60° apparent field
• Anti-reflective coating 0.1 %
• H-alpha optimized flat-field design

Ergonomics and transport

Despite its 100 mm aperture, the LS100MT is easy to transport thanks to :

• Integrated solar handle with red dot finder
• Permanent alignment of the pointing system
• 8-inch Vixen rail for optimal balancing
• Tailor-made rigid case for complete protection
