With a multi-coated 30mm cemented lens, this f/4 scope has a focal length of 120mm, ideal for autoguiding a main scope with an effective focal ratio of about 1200mm or less. This guide scope focuses with a threaded front objective cell that allows an adjustable back focus of 0-20mm. You can directly thread a ZWO camera such as the ASI120-series onto the male M42x0.75 threads on the scope. Or you can directly insert a camera with a 1.25" nosepiece or a smaller ZWO autoguiding camera such as the ASI290MM-Mini or ASI120MM-Mini and lock it down with the two locking screws. This little scope comes with guide rings and a Vixen/Synta style dovetail, which makes it easy to mount on nearly any telescope. The dovetail base also includes a ¼-20 screw hole for mounting on a photo tripod if you wish to use the scope as a camera lens or for visual viewing with an eyepiece. The entire scope, without the camera, is just 4.8” long (about 123mm). A camera is not included with this guide telescope.
