This Internal Double Stack Module from Lunt Solar can be added to an existing LS130MT Lunt Ha telescope. \u003c\/p\u003e\n\u003cp\u003eThis Lunt Solar 130 mm Ha Solar Double Stack Module is equipped with Lunt's True Doppler Tuning via a pressure tuning method. This is a solar Ha band tuning technique using air pressure changes within the chamber containing the Internal Etalon Ha Filter. True Doppler Tuning allows for a Doppler shift into and away from the user which adds a 3D-like component to the viewing experience. While it has minimal effect on prominences due to their location at the edge of the disk, it does have an effect on filaments and active regions on the surface facing us, not at the edge.\u003c\/p\u003e\n\u003cp\u003eWhile looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The pressure tuning system provides an order of magnitude more precision to the tuning of these desired Ha image features than is possible with a tilting etalon filter system.\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLunt Solar Systems Internal Double Stack Module\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned to install in an existing LS130MT Solar Telescope\u003c\/li\u003e\n\u003cli\u003eAdds Double Stacking capability\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 7 pounds\u003c\/li\u003e\n\u003cli\u003eDimensions: 16\" x 16\" x 12\"\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eSingle Stack Bandpass: 0.45Å (telescope internal etalon)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eModule Etalon Bandpass: 0.35Å — individually verified\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDS Combined Bandpass: \u0026lt;0.28Å — LFPT (0.35Å) + MT internal PT (0.45Å)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTuning: Independent Doppler True Barometric pressure tuning\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eInstallation: Customer-installed — no factory return required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lunt Solar Systems","offers":[{"title":"Default Title","offer_id":43229903454321,"sku":"LUN-DSII\/LS130MTP","price":4193.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/Double_Stack_LS130_LS152.webp?v=1778528703","url":"https:\/\/khanscope.com\/products\/lunt-solar-internal-double-stack-module-for-ls130mt-dsii-ls130mtp","provider":"Khan Scope Centre","version":"1.0","type":"link"}
