Meade® Illuminated Reticle Eyepiece Systems Wireless and corded models, each with advanced features, to suit any observing requirement. These special-purpose eyepieces include reticles with etched crossline patterns, internally red-illuminated so that the lines are clearly visible against a dark sky. All eyepieces are 31.7mm(1.25") O.D. Modified Achromatic 12mm Illuminated Reticle Astrometric Eyepiece 31.7mm(1.25"): A high-precision eyepiece for a wide range of astronomical measurements, the Meade MA12mm 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-crossline 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 eyepieces 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 MA12mm Astrometric Eyepiece is supplied complete with wireless illumination control and internal batteries.
