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! \u003cb\u003e The 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. \u003cb\u003e The 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\/b\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\u003ch4\u003e News Release !
