Farpoint manufactured the original 14″ bars for OPT (Oceanside Photo \u0026amp; Telescope), who sold them under the Radian Telescopes brand. With OPT now closed, we sell the line direct under the 57.3 Series name — and this 6″ brings the same design to the smallest rigs. The original length lives on as the 57.3 Series 14″ bar .\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy choose the compact 6″ length?\u003c\/strong\u003e\u003cbr\u003eSmall refractors, guide scope rigs, and accessory assemblies don't need 14″ of bar — the 6″ keeps the footprint and weight down while giving you a full D-size dovetail. Need more reach? Step up to the 14″ original Radian length or the 21.5″ bar .\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat mounts will this work with?\u003c\/strong\u003e\u003cbr\u003eAny mount with a D-size (Losmandy-style) saddle.
