William Optics 50/200 Refractor Guidescope RotoLock Red OTA

William Optics 50/200 Refractor Guidescope RotoLock Red OTA: red guider-OTA

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.

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.

Assembly

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.

Featured accessories

Combine the tube with the William Optics 50mm tube rings for scratch-free, adjustable mounting.

For whom yes and for whom no

• ✓ Astrophotographers looking for a lightweight, classic guide scope
