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!\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe Parallizer™ 2 inch-to-1.25 inch adapter utilizes a patented design that 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\u003cp\u003e\u003cbr\u003eThe adapter’s non-marring clamp screw is set at 45 degrees, camming the accessory down against the adapter flange when tightened. The Parallizer has zero in-focus loss, and does not require a screw slot to seat fully in a drawtube. It is threaded for 48mm (2”) filters.\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 2\"-1.25\" Adapter\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\n\u003cp\u003e \u003ca title=\"Parallizer Instructions\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Parallizer.pdf?v=1668192855\" target=\"_blank\"\u003eUser Instructions\u003c\/a\u003e\u003c\/p\u003e","brand":"Howie Glatter","offers":[{"title":"Default Title","offer_id":43125733392613,"sku":"HG-EA20-205P","price":126.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/howie-glatter-parallizer-2-1-25-adapter-ea20-205p-astronomy-plus_8bc64e00-4e7e-4d67-b414-6b8887b14227.png?v=1690484347","url":"https:\/\/istronomyplus.com\/products\/howie-glatter-parallizer-2-1-25-adapter-ea20-205p","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
