Meade Series 4000 Illuminated Reticle Eyepieces

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 1.25" O.D.

Series 4000 Plössl 9mm Illuminated Reticle Eyepiece: 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 reticle's 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 observer's eye. The upper (lens) section of the eyepiece rotates on a fine thread for precise diopter adjustment to the user's eye. Reticle pattern is a double crossline with two concentric circles.

Wireless Model: The Series 4000 Plössl 9mm Wireless Illuminated Reticle Eyepiece includes a red LED illuminator, operated from internal batteries, with variable brightness control; batteries are included with each eyepiece.

Corded Model: The same eyepiece as above, but with 6 ft. cord and connector for direct plug-in to the control panels of Meade LX200, LX200GPS, and ED/APO telescopes. Separation of the power source and eyepiece permits reticle brightness adjustments to be made during an exposure without risk of vibrating the telescope. Red LED brightness control is effected from the telescope's hand controller or control panel.

Modified Achromatic 12mm Illuminated Reticle Eyepiece: The MA 12mm Illuminated Reticle Eyepiece includes a 3-element, fully-coated MA optical system with good eye relief, diopter adjustment, and double crossline reticle. An excellent, lower-cost alternative to the Series 4000 Plössl 9mm model, above.

Wireless Model: Includes red LED illuminator, variable brightness control, and internal batteries.

Corded Model: With 6 ft. cord and connector for the control panels of Meade LX200, LX200GPS and ED/APO telescopes.
