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 prism and
eyepiece. The #126 2x Barlow Lens, a compact 2-element alternative to the #140,
may also be employed with any
L X 2 0 0 - A C F
Series telescope.
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 applications, and in Neutral Density as a lunar glare-reduction filter.
Series 4000 Nebular Filters: A modern boon to the city-dwelling deep-space
o b s e r v e r, the interference nebular filter effectively cancels out the effects of most
urban light pollution, while leaving the light of deep-space nebular emissions virtually
unattenuated. Meade Series 4000 Nebular Filters utilize the very latest in coating
t e c h n o l o g y, and are available with threaded cells for eyepieces or for attachment to
the rear cells of Meade Advanced Coma-Free Telescopes models.
Zero Image-Shift Microfocuser: Now you can obtain extremely precise image focus
- truly to a microscopic level - during visual and astrophotographic applications, and,
during CCD applications, simultaneously maintain precise image centration on even
the smallest CCD chips. Optional equipment on 8", 10", 12" and 14" LX200-ACF
Advanced Coma-Free models, the Meade Zero Image-Shift Microfocuser operates at
4 speeds from extremely slow to fast; the entire microfocusing operation is actuated
through the Autostar II handbox and powered from the telescope’s control panel.
Coarse manual focusing is effected through the telescope’s manual focus knob.
Variable Tele-Extender: For eyepiece-projection photography of the Moon and the
planets, a Tele-Extender is required. The variable Tele-Extender threads onto the
telescope’s eyepiece-holder, into which is inserted an eyepiece of typically about
26mm focal length; the 35mm camera body couples to the tele-extender by means of
a T-Mount. The Meade Variable Tele-Extender permits a range of projection images.
Series 5000 2" Diagonal with Enhanced 99% Reflecting Coatings: The Series
5000 2" diagonal (provided as standard equipment on LX200 16" telescopes and as
an option on other sizes) delivers premium performance with 99% of the light reflected
to the eyepiece. This diagonal allows you to use the advanced 2" eyepieces like
Meade’s Series 5000 UWA and SWA for wider, sharper fields. The Series 5000 2"
Diagonal comes with a 1.25" adapter for using standard sized eyepieces.
Series 4000 Plössl 9mm Illuminated Reticle Eyepiece: The most advanced
commercially-available illuminated reticle eyepiece, this Series 4000 Plössl 9mm
model, powered by an internal battery, 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.
#62 T-Adapter: The T-Adapter is the basic means of prime-focus photography
through all Meade Advanced Coma-Free 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.
#777 Off-Axis Guider: The Off-Axis Guider provides a means during long-exposure
astrophotography for the photographer to monitor the tracking of the telescope
to assure that the telescope remains precisely positioned on the object being
photographed. Like the T-Adapter, the Off-Axis Guider couples the camera body to
the telescope but it also causes a small amount of the guidestar’s incoming light to
be diverted at a right angle, where the star’s position can be examined for tracking
