Bresser 90\u00b0 2-inch star diagonal: comfortable viewing with 2-inch aperture<\/strong><\/h2>\n\n\n\n

With the Bresser 90-degree 2-inch zenith mirror, you can comfortably look into the eyepiece from above instead of having to crouch under the telescope. The mirror is made entirely of metal and features a dielectric coating with a 93% reflectivity rating that is resistant to moisture and aging.<\/p>\n\n\n\n

The 2-inch aperture is its biggest advantage: it allows you to use 2-inch wide-field eyepieces for maximum field of view, which is important for deep-sky observations with telescopes that have a long focal length. An included adapter also makes the mirror compatible with all your 1.25-inch eyepieces.<\/p>\n\n\n\n

Brass compression fitting<\/h4>\n\n\n\n

The eyepiece clamp works with a brass ring that exerts even pressure. Your eyepieces stay free of clamping screw scratches, even if you change them frequently.<\/p>\n\n\n\n

Which telescopes<\/h4>\n\n\n\n

Intended for refractors and for Schmidt-Cassegrain and Maksutov telescopes with a 2-inch focuser, including the Bresser Messier refractors with 2.5-inch Hexafoc. Not needed on a Newtonian: there you are already looking into the side of the tube.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

Combine the star diagonal with the Bresser 2-inch polarizing filter to dim the bright moon, or with the Plossl eyepieces for the 1.25-inch part of your kit.<\/p>\n\n\n\n
