Visit LS50THa Premium Kit<\/strong> represents the complete Lunt 50mm solar platform experience. This system combines the performance of the LS50THa Pressure-Tuned with a new-generation LS50C compact double-stack filter to deliver exceptional contrast and detail in the solar chromosphere.<\/p>\n The LS50C double-stack filter, individually tested on Lunt precision metrology equipment, attaches directly to the front of the optical tube in seconds, without tools. This configuration places a 0.35 \u00c5 tilt-tuned standard in series with the 0.6 \u00c5 Pressure-Tuned internal standard, reducing the combined bandwidth to around 0.30 \u00c5.<\/p>\n The results are spectacular: surface details gain in depth, filaments become more complex and active regions reveal their full magnetic architecture.<\/p>\n At a combined bandwidth of around 0.30 \u00c5, the solar chromosphere reveals structures invisible with a simple stack system:<\/p>\n The Sun ceases to be a simple textured surface and becomes a dynamic landscape rich in relief and contrast.<\/p>\n The LS50THa Premium uses the exclusive Doppler True Pressure Tuning<\/strong> for fine-tuning the bandwidth position on the H-Alpha line.<\/p>\n This uniform adjustment across the entire aperture allows :<\/p>\n The kit includes a 7.2-21.5 mm zoom eyepiece to cover a wide range of magnifications without changing eyepieces:<\/p>\n This flexibility is particularly useful when solar phenomena evolve rapidly or when atmospheric conditions change.<\/p>\n The eyepiece features :<\/p>\n The Rack & Pinion 1.25\u2033 CNC aluminum and brass eyepiece holder guarantees smooth, extremely precise focusing.<\/p>\n It includes :<\/p>\n The Vixen 6\u2033 dovetail ensures optimal system balancing with the double stack filter installed.<\/p>\n The LS50THa Premium Kit is the ideal solution for solar observing enthusiasts wishing to exploit the full potential of the Lunt 50 mm platform. Thanks to its new-generation double stack system, high-precision CNC focuser and versatile zoom eyepiece, it offers an immersive, scalable and extremely detailed solar observing experience, for both visual and imaging purposes.<\/p>","protected":false},"excerpt":{"rendered":" LS50THa Premium Kit : T\u00e9lescope solaire H-Alpha 50 mm Double Stack haute performance Le LS50THa Premium Kit repr\u00e9sente l\u2019exp\u00e9rience compl\u00e8te de la plateforme solaire Lunt 50 mm.
