The 6x magnification 30 mm objective diameter crosshair finder telescopes are the ideal addition to small and medium sized binoculars. The inverted-position version is recommended for Newtonian telescopes, while the straight-position ones are ideal companions for binoculars with a lens and Schmidt-Cassegrain.
The advantage of the optional spring-load mount is that the viewfinder can be paralleled by adjusting just two screws, as a spring-loaded solution instead of a third screw aids adjustment. Sharpness can be adjusted by rotating the lens, which is locked in place by a ring behind the mount. The finder scope has a field of view of 7°.
