One steps a 2 inch blocking filter or focuser down to 1.25 inch, the other threads onto a T2 blocking filter so you can drop in 2 inch eyepieces. Both are metal bodied and both use a non marring brass compression ring.\u003c\/p\u003e\n    \u003cp\u003eADP2-1.25 is the part to reach for when you own a 2 inch Lunt blocking filter but want to observe with 1.25 inch eyepieces, and it works equally well as a general reducer inside any 2 inch diagonal or focuser. The brass ring grips the barrel evenly instead of digging a thumbscrew dimple into it.\u003c\/p\u003e\n    \u003cp\u003eLST2-2 inch goes the other way. Remove the 1.25 inch eyepiece tube from your blocking filter, thread this adapter onto the exposed T2 thread, and you can use 2 inch eyepieces. Lunt lists it for its blocking filters, hydrogen alpha and calcium K telescopes except the LS35THa, and Ca-K modules. Solar viewing still demands the telescope's proper filtration.\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\/2-1.25.jpg?v=1743113228\" alt=\"Lunt 2 inch to 1.25 inch telescope adapter for blocking filters, black anodized barrel\"\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\u003eBrass Compression Ring\u003c\/b\u003e - both adapters clamp the barrel evenly so thumbscrews never scar an eyepiece or camera nose.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eStep Down Fit\u003c\/b\u003e - the ADP2-1.25 takes a 2 inch blocking filter, diagonal or focuser down to standard 1.25 inch accessories.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eT2 To Two Inch\u003c\/b\u003e - the LST2-2 inch threads straight onto the T2 thread left behind when the 1.25 inch eyepiece tube is removed.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eWide Field Access\u003c\/b\u003e - opening a Lunt blocking filter to 2 inch eyepieces lets you use longer focal length wide field designs.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eAll Metal Bodies\u003c\/b\u003e - machined metal construction with no plastic in the load path, so the joint stays square under a heavy eyepiece.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cb\u003eBroad Compatibility\u003c\/b\u003e - listed for Lunt blocking filters, hydrogen alpha and Ca-K telescopes other than the LS35THa, and Ca-K modules.\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\/LST2-2in-triangle.jpg?v=1743112830\" alt=\"Lunt T2 to 2 inch eyepiece tube adapter with internal brass compression ring\"\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\u003eType\u003c\/td\u003e\n\u003ctd\u003eMachined mechanical adapters for Lunt blocking filters, diagonals and focusers\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eModel \/ SKU\u003c\/td\u003e\n\u003ctd\u003eADP2-1.25, LST2-2 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eADP2-1.25 function\u003c\/td\u003e\n\u003ctd\u003esteps a 2 inch blocking filter, diagonal or focuser down to 1.25 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eLST2-2 inch function\u003c\/td\u003e\n\u003ctd\u003ethreads onto a T2 blocking filter thread to accept 2 inch eyepieces\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eRetention method\u003c\/td\u003e\n\u003ctd\u003enon marring brass compression ring on both adapters\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eOptical elements\u003c\/td\u003e\n\u003ctd\u003enone, both parts are purely mechanical\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBody material\u003c\/td\u003e\n\u003ctd\u003emetal;
