Total internal reflection is a property of the glass-air boundary itself, so nothing is lost to coating efficiency and nothing degrades with age — an aluminised mirror slowly dulls, a prism does not.\u003c\/p\u003e\u003cp\u003eThe trade is that light passes through glass, so the entry and exit faces are multicoated to hold down surface reflections and the scatter that would otherwise reduce contrast on planetary detail. At f\/6 and slower, which covers most of the Takahashi refractor range in visual use, a prism of this quality introduces no aberration that the eye can separate from the telescope's own.\u003c\/p\u003e\u003cp\u003eThe compression ring is the mechanical half of the design.
