More about the series Series 4000...
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. The most advanced commercially-available illuminated reticle eyepiece, this Series 4000 Plössl 9mm model includes micrometric x-y positioning controls which greatly facilitate locking onto the guide star: turn the finely-threaded controls and place the reticles crossline pattern precisely at the desired position in the field. The sharp, high-power imaging of the 4-element, multi-coated Plössl optical system is complemented by a rubber eyecup (foldable for eyeglass wearers) that shuts out distracting stray light from the observers eye. The upper (lens) section of the eyepiece rotates on a fine thread for precise diopter adjustment to the users eye. Reticle pattern is a double crossline with two concentric circles.
