The 3\" wide Losmandy D-style profile provides a much more stable connection to the mount saddle compared to the narrower Vixen style.

It provides enough length to space the tube rings appropriately for solid support and allows for sliding the telescope forward or backward in the saddle to achieve precise balance, which is critical for the performance of a GoTo mount like the CGX.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I attach guide scope rings and other accessories to this Baader 3\" dovetail bar?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this bar is designed for custom builds.

You need a bar that is long enough to accommodate that spacing with extra room on either end. A 10\" (250mm) bar is typically suitable for refractors up to about 100-115mm in aperture, allowing enough space to mount the rings and slide the assembly for balancing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy is the black anodized finish on the Baader 3\" bar important?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe black anodized finish serves two purposes.
