Visit 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.
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 :
The user no longer simply observes the Sun, but actually explores its dynamic structure.
The LS50THa Enhanced Kit includes three Flat-Field eyepieces optimized for solar observation:
All eyepieces feature :
This range of magnifications makes it possible to instantly adapt observation to the atmospheric conditions and phenomena observed.
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:
This improvement immediately transforms user comfort and prepares the system for solar imaging.
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.
