These waterproof telescopes with reduced minimum focusing distance of 0.3m (0.98ft) feature endless horizontal drive for smooth precise pointing and angular measurement, and they can be attached to either flat- or spherical- head tripods. In addition, a pentaprism mirror enables the viewing of a circular bubble as an erect image. They come with optional, high- and low-power eyepiece lenses, and attachable diagonal eyepiece lens for use in confined spaces. Another useful feature is clampless horizontal alignment.
