Meade MA 12mm Illuminated Reticle Astrometric Eyepiece (1.25"), Wireless
Ways to Save
A high-precision eyepiece for a wide range of astronomical measurements, the Meade MA 12mm Astrometric Eyepiece is an important tool for the advanced amateur. The laser-etched reticle (below) is evenly illuminated by an internal red LED, with illumination intensity variable from bright to faint.
Four types of measuring scales are included, for measuring double star angular separations, position angles, planetary diameters, and lunar crater diameters, as well as many other useful astronomical measurements. Included also is a double cross line scale for long-exposure photo-guiding, making the Meade Astrometric Eyepiece truly an all-purpose illuminated reticle system.
The 3-element Modified Achromatic optical system yields sharp images across the full field of view; optics are coated for increased light transmission. The eyepiece's diopter adjustment allows for sharp focusing of the reticle to the observers eye, and a rubber eyecup (foldable for eyeglass wearers) shields the eye from extraneous light.
The MA 12mm Astrometric Eyepiece is supplied complete with wireless illumination control and internal batteries.
