About the Meade Series 4000 12mm MA Astrometric Illuminated Reticle Eyepiece - Wireless...
A high-precision Meade Telescope 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 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 Meade MA12mm Astrometric Eyepiece optical system yields sharp images across the full field of view; optics are coated for increased light transmission. The Meade Telescope Eyepiece''s diopter adjustment allows for sharp focusing of the reticle to the observer''s eye, and a rubber eyecup shields the eye from extraneous light.
The Meade MA12mm Astrometric Eyepiece is supplied with wireless illumination control and internal batteries.
