William Optics 50\/200 Refractor Guidecope RotoLock: lightweight guide OTA with RotoLock<\/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 tubing weight of only 460 g (1 lb), this OTA hardly strains your mounting setup. The 1.25-inch RotoLock clamps your guide camera securely in place with a twist; the large ribbed ring also works with gloves. This model is black.<\/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<\/div>\n<\/div>\n\n\n\n
