Series 4000 Eyepieces: Meade professional-level Series 4000 eyepieces enable any LXD55-Series telescope to reach its maximum capability. Note: Because of pupillary diameter restrictions of the human eye, no eyepiece of longer focal length than 32mm can effectively be used with the short focal ratio of the Model SN-6, or longer than 26mm with Models SN-8 or SN-10. Series 3000 Plössl Eyepieces produce excellent results on all LXD55-Series models. Use in focal lengths from 5mm through 25mm.

#140 Series 4000 2x Apochromatic Barlow Lens: Designed to complement premium-grade eyepieces, such as the Meade Series 3000 and 4000 oculars, the #140 doubles any eyepiece magnification without in any way reducing the level of image resolution or color correction. The Meade #126 2x Telenegative Barlow and #127 2x-3x Variable Barlow (p. 110) are fine lower-cost alternatives to the #140, and yield excellent performance on LXD55-Series telescopes.

Series 4000 8mm - 24mm Zoom Eyepiece: High-resolution, 7-element multi-coated optics with 55° field at 8mm. Graduated scale in 1mm units indicates exact focal length in use. An excellent complement to all Meade telescope models. (See also p. 104.)

Series 4000 Photo-Visual Color Filters: A significant aid in enhancing image contrast on the Moon and planets, Meade Series 4000 color filters thread into the barrels of all Meade 1.25" eyepieces, and into the barrels of virtually all other 1.25" eyepiece brands as well.

Series 4000 Nebular Filters: Meade #908B, #908N, and #908X filters effectively block the most common forms of light pollution, while allowing nebular light to pass through essentially unattenuated.

Camera Adapters: For photography through an LXD55-Series telescope, the Meade Basic Camera Adapter is required. Alternately, the Variable-Projection Camera Adapter permits a continuous range of projection magnifications. Each camera adapter requires a T-Mount for the specific brand of 35mm camera employed.

Power Adapters and Cords: In addition to their standard-equipment battery packs LXD55-Series telescopes may also be powered from standard 115v AC home outlets with the #547 AC Adapter. Alternately, any model may be powered in the field from an automobile cigarette lighter plug by using the #607 Power Cord (shown). The #547 and #607 include 25 ft. cords.
