Nothing sits in the light path to soften contrast, so the system performs at both low and high magnification. High contrast coatings run through the optical train to keep scatter down across the full solar disk.\u003c\/p\u003e\n    \u003cp\u003eDoppler True pressure tuning is the reason this telescope behaves differently from tilt tuned designs. The internal etalon holds a bandpass below 0.45 Angstrom at 656 nm, and the pressure tuner shifts it toward and away from you. Follow a filament from base to tip and watch its structure move through the line, adding depth to what you see.\u003c\/p\u003e\n    \u003cp\u003eAt 900 mm and f\/6 the LS152THa suits visual observers and imagers alike. Choose a B1200 diagonal for visual work, a B1800 diagonal for a wider field, or a B3400 straight through unit for large sensors, and step up to a 2.5 inch Feather Touch focuser in the top configuration. An optional Ca-K module opens a second wavelength.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n    \u003cdiv class=\"kt-sq\"\u003e\n      \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/8273\/7521\/files\/LS152THa-Solar-Telescope-Lunt.jpg?v=1743112797\" alt=\"Lunt LS152THa 152mm dedicated hydrogen alpha solar telescope in pearl white with red accents\"\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"kt-features\"\u003e\n  \u003cdiv class=\"kt-features-copy\"\u003e\n    \u003ch3 class=\"kt-section-heading\"\u003eKey Features\u003c\/h3\u003e\n    \u003cul class=\"kt-feature-list\"\u003e\n      \u003cli\u003e\n\u003cb\u003e152mm Unobstructed\u003c\/b\u003e - aperture with no central obstruction, so the system holds contrast at both low and high magnification.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eHD Etalon\u003c\/b\u003e - is a single internal interference unit rated below 0.45 Angstrom at 656 nm for high surface and edge detail.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eDoppler True Tuning\u003c\/b\u003e - shifts the passband toward and away from you, adding a three dimensional quality to filaments and active regions.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eBlocking Filter Range\u003c\/b\u003e - covers the B1200 diagonal for visual use, the B1800 diagonal for wider fields, and the B3400 straight through for large sensors.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eFeather Touch Option\u003c\/b\u003e - replaces the standard 2 inch rack and pinion with a 2.5 inch dual speed unit in the top configuration.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eCa-K and Night Use\u003c\/b\u003e - are available through an interchangeable calcium K module and a separate backing plate and focuser kit.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-features-img\"\u003e\n    \u003cdiv class=\"kt-sq\"\u003e\n      \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/8273\/7521\/files\/LS152THa-Lunt-Solar-Telescope-2.jpg?v=1743112797\" alt=\"Rear of the Lunt LS152THa showing the pressure tuner, blocking filter and focuser assembly\"\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"kt-specs-wrap\"\u003e\n\u003ctable class=\"kt-specs\"\u003e\n  \u003ctr\u003e\u003cth colspan=\"2\"\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eModel \/ SKU\u003c\/td\u003e\n\u003ctd\u003eLS152THa\/R\u0026amp;P, LS152THa\/B1200RP, LS152THa\/B1800RP, LS152THa\/B3400FT\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eDedicated hydrogen alpha refractor, 100 percent unobstructed, single interference HD etalon\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eAperture\u003c\/td\u003e\n\u003ctd\u003e152 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e900 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eFocal Ratio\u003c\/td\u003e\n\u003ctd\u003ef\/6\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBandwidth\u003c\/td\u003e\n\u003ctd\u003eLess than 0.45 Angstrom at 656 nm, single stack\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eEtalon\u003c\/td\u003e\n\u003ctd\u003eInternal single interference HD etalon, UV grade fused silica\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBlocking Filter\u003c\/td\u003e\n\u003ctd\u003eB1200 diagonal, B1800 diagonal, or B3400 straight through\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eFocuser\u003c\/td\u003e\n\u003ctd\u003e2 inch rack and pinion standard;
