William Optics 50\/200 Refractor Guidescope RotoLock Red OTA: red guider-OTA<\/strong><\/h2>\n\n\n\n

The William Optics AC 50\/200 is a compact refractor guide scope with a 50mm (2 inch) aperture and a 200mm focal length (f\/4). Its 5.7-degree field of view makes alignment and finding a guide star easy, and the integrated dew shield keeps the front lens free from condensation.<\/p>\n\n\n\n

With a tube weight of only 460g (1 lb), this OTA barely stresses your mount. The 1.25-inch RotoLock firmly clamps your guide camera centered with a twist; the large knurled ring also works with gloves. This version is red.<\/p>\n\n\n\n

Assembly<\/h4>\n\n\n\n

You mount the tube parallel to your main telescope, for example in the William Optics 50 mm tube clamps on a prism rail. By sliding the tube in the clamps, you align it exactly with your main optics.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

Combine the tube with the William Optics 50mm tube rings for scratch-free, adjustable mounting.<\/p>\n\n\n\n
