Lunt THa H-alpha Solar Telescopes

Lunt THa H-alpha solar telescopes are dedicated hydrogen-alpha refractors for viewing prominences, filaments and surface detail in the chromosphere. The line runs from the compact LS40THa and LS50THa, sold in Standard, Enhanced and Premium PLUS kits, to the large pressure-tuned LS152THa, LS230THa Double Stack and LS300THa.

Matching double stack filters and modules, clamshell rings and adapters are also part of the line, so a THa telescope can be upgraded for a narrower bandpass and more contrast.
