Description
Prism rails, known as dovetail bars, serve as primary fixtures for mounting telescopes onto astronomical mounts. Additionally, these rails commonly secure additional accessories to the telescope’s optical tube, such as an internal focuser or a camera.
In astronomy, there are two established standards: the relatively narrow rails pioneered by Japanese manufacturer Vixen and the wider Losmandy rails, measuring 3 inches in width, primarily intended for supporting heavy optics. In photography, the Arca-Swiss standard is recognized for clamping to camera tripods.
Most astronomical mounts are tailored to one of these two standards. Medium-sized mounts and larger often feature a dual mounting saddle capable of accommodating both standards.
