Star Diagonals

Astronomical observation usually requires the telescope to tilt up significantly, which can make straight-thru viewing awkward and uncomfortable. A diagonal solves this comfort problem by using a mirror to direct the light at a 90° angle toward the eyepiece. Explore Scientific has both 2-inch and 3-inch diagonals with dielectric-coated mirrors that are 99% reflective.
