Lunt LS50THa Kit Enhanced

LS50THa Enhanced Kit: 50 mm H-Alpha solar telescope with precision focuser and full range of eyepieces

The LS50THa Enhanced Kit takes the excellent performance of the H-Alpha LS50THa solar system and incorporates major improvements for observers wishing to take their solar exploration a step further. This kit focuses on two essential elements: mechanical precision and magnification versatility.

Thanks to its unobstructed 50 mm aperture, internal Pressure-Tuned Doppler True standard and 0.6 Å bandwidth, the LS50THa Enhanced accurately reveals the dynamic details of the solar chromosphere. Its new CNC rack-and-pinion eyepiece holder and three dedicated eyepieces offer a much more advanced and comfortable observing experience.

Pressure-Tuned Doppler True technology

One of the most popular features of the LS50THa range is the adjustable-pressure internal standard system. In contrast to a tilt adjustment system, the Doppler True Pressure Tuning acts uniformly on the entire standard to precisely modify the position in the H-Alpha line.

This setting allows :

• Increase the brightness of protuberances
• Enhance the contrast of surface details
• Explore different depths of the chromosphere
• observe evolving solar structures in real time

The user no longer simply observes the Sun, but actually explores its dynamic structure.

Three eyepieces for every situation

The LS50THa Enhanced Kit includes three Flat-Field eyepieces optimized for solar observation:

• 8 mm - 44x : ideal for active areas and fine details of protuberances
• 12 mm - 29x : versatile magnification for general observation
• 16 mm - 22x : perfect for full-disc views and protrusion surveys

All eyepieces feature :

• 60° apparent field of view
• 0.1 % anti-reflective coating
• 1.25″ format

This range of magnifications makes it possible to instantly adapt observation to the atmospheric conditions and phenomena observed.

High-precision CNC Rack & Pinion eyepiece holder

The helical eyepiece holder of the standard model is replaced here by a rack-and-pinion system (Rack & Pinion) made of CNC aluminum and brass.

Advantages:

• A much smoother ride
• Integrated brake with adjustable resistance
• Perfect focus retention
• 6 to 8 lbs load capacity for cameras and accessories
• Brass clamping ring protects accessories

This improvement immediately transforms user comfort and prepares the system for solar imaging.

Double stack compatible

Like all Lunt 50 mm systems, the LS50THa Enhanced is fully compatible with the new-generation LS50C double-stack filter.

The addition of this filter reduces the combined bandwidth to around 0.30 Å, greatly enhancing the contrast of surface structures and chromospheric details.
