Furthermore, neither telescope module will need to be returned to the factory for double-stacking.\u003c\/p\u003e\n\u003cp\u003eYou can purchase the 80 mm or 100 mm single stack universal telescope initially and add the SFPT to make it a double stack unit later. This will make it more affordable to purchase our a new universal telescope and still have room for upgrades. Once you upgrade your Lunt Universal Telescope with the double stack unit, you will be able to see the finer details not previously visible.\u003c\/p\u003e\n\u003cp\u003eFind the latest news and photos of the Sun at\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.nasa.gov\/sun\"\u003eN\u003c\/a\u003e\u003ca href=\"https:\/\/www.nasa.gov\/sun\" rel=\"noopener\" target=\"_blank\"\u003eA\u003c\/a\u003e\u003ca href=\"https:\/\/www.nasa.gov\/sun\"\u003eSA\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eLunt Internal Double Stack Module \u003cbr\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003ch3\u003eWarranty \u0026amp; Manuals\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eLunt 5-Year Warranty\u003c\/p\u003e","brand":"Lunt","offers":[{"title":"Default Title","offer_id":43125732901093,"sku":"LS-DSII\/SFPTP","price":2093.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/lunt-internal-double-stack-module-for-ls80tha-ls80haptdsii-astronomy-plus.webp?v=1690484342","url":"https:\/\/istronomyplus.com\/products\/lunt-internal-double-stack-module-for-ls80tha-ls80ha-pt-dsii","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
