Series 4000 8 - 24mm Zoom Eyepiece: The internal zoom optics of this eyepiece move on smooth, precisely machined surfaces which maintain optical collimation at all zoom settings. A scale graduated in 1mm units indicates the zoom focal length in operation. An excellent addition to any eyepiece set.

#140 2x Barlow Lens: A 3-element design, doubles each eyepiece power while maintaining uncompromised image resolution, color correction, and contrast. Insert the #140 into the telescope’s eyepiece holder first, followed by the diagonal (as appli- cable) and eyepiece. The #126 2x Barlow Lens, a compact 2-element alternative to the #140, may also be employed with any LXD75-Series telescope.

#905 Variable Polarizer (1.25"): The #905 system includes 2 Polarizer filters mount- ed in a specially-machined cell, for glare-reduction in observing the Moon. Rotate the thumbscrew at the side of the unit to achieve light transmission between 5% and 25% of its original value. The #905 inserts into the diagonal of the telescope, followed by an eyepiece.

Series 4000 Photo-Visual Color Filters: Color filters significantly enhance visual and photographic image contrast of the Moon and planets. Each filter threads into the barrel of any Meade 1.25" eyepiece, and into the barrels of virtually all other eyepiece brands as well. Meade filters are available in 12 colors for lunar and planetary appli- cations, and in Neutral Density as a lunar glare-reduction filter.

Series 4000 Nebular Filters: A modern boon to the city-dwelling deep-space observer, the interference nebular filter effectively cancels out the effects of most urban light pollution, while leaving the light of deep-space nebular emissions virtual- ly unattenuated. Meade Series 4000 Nebular Filters utilize the very latest in coating technology, and are available with threaded cells for eyepieces or for attachment to the rear cells of Meade Schmidt-Cassegrain models.

#928 45° Erect-Image Diagonal Prism: Primarily used for terrestrial viewing, this prism presents a correctly-oriented image at a comfortable 45° viewing angle.

#547 Power Adapter with Cable: Includes a 25 ft. cord and permits powering from a standard home (115v AC) outlet. The #547F Power Adapter is available for 220v AC outlets.

#607 Cigarette Lighter Adapter: Power a LXD75-Seriestelescope by means of an automobile cigarette lighter plug. The LXD75 telescope may be powered for a full night’s observing without risk of car-battery drain.

#62 T-Adapter:The T-Adapter is the basic means of prime-focus photography through all Meade Schmidt-Cassegrain models. Thread the T-Adapter on to the rear cell of your telescope, followed by a T-Mount for your 35mm camera, and the camera body is rigidly coupled to the telescope.

Piggyback Brackets: Piggyback photography is one of the most popular and easiest ways to get started in astrophotography. Attach your 35mm camera, with its own 35mm-to-250mm lens, atop your LXD75 in equatorial mode, and guiding the camera through the main telescope, wide-field photos of the Milky Way of remarkable detail and clarity can be taken.

Dew Shield: In moist climates, water particles suspended in the atmosphere may condense on the front surface of the telescope's correcting plate. This dew formation may be inhibited to a significant extent by the addition of a dew shield, essentially an extension tube attaching to the front-cell of the telescope. #608 for Meade Schmidt- Cassegrain SC-8 model.

#905 Variable Polarizer (1.25"): #1A Skylight Filter: The #905 system includes 2 Polarizer filters mounted in a specially-machined cell, for glare-reduction in observ- ing the Moon. Rotate the thumbscrew at the side of the unit to achieve light trans- mission between 5% and 25% of its original value. The #905 inserts into the diago-
