Universal 50mm viewfinder and guide telescope with a focal length of 220mm
Excellent 8×50 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.
