There are adapters and holders on the market that are advertised as “centering” or “self-centering”, but even if an accessory is pushed off-center a millimeter or more by clamping, that will not introduce a significant problem if the accessory and holder axis remain parallel. This is true even with a laser collimator. In contrast, angular misalignment between the accessory and the drawtube axis of even a few arc minutes can be detrimental, especially for collimation tools and camera adapters. In short, centering is nice, but parallelism is golden!\u003cbr\u003eThe Parallizer™ patented design insures parallel alignment with the drawtube axis of optical accesories such as eyepieces, camera adapters, and collimation tools. The Parallizer’s unique, patented alignment feature assures that the drawtube and accessory axis will always be dead parallel.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003eUseful for aligning the returning beam on collimator face.\u003cbr\u003e\u003cbr\u003eRemovable diffractive optical element for use in Glatter Holographic Collimators.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eHowie Glatter Parallizer T-Adapter \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cdiv class=\"entry-content\"\u003e\n\u003cp\u003eHowie Glatter Limited Lifetime Warranty\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Howie Glatter","offers":[{"title":"Default Title","offer_id":43125733327077,"sku":"HG-EA20-205T","price":126.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/howie-glatter-parallizer-t-adapter-ea20-205t-astronomy-plus_8fb11e3c-4d22-4601-a2ee-2f48e9f1a716.png?v=1690484348","url":"https:\/\/istronomyplus.com\/products\/howie-glatter-parallizer-t-adapter-ea20-205t","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
