LX200-ACF: YOUR PERSONAL
WINDOW TO THE UNIVERSE
The Meade LX200-ACF models are extremely versatile, high-resolution telescopes.
With pushbutton controls, precision GPS alignment, true-level and North electronic
sensors, automatic tracking of celestial objects, periodic error correction for both axes,
and a library of 145,000+ objects in the AutoStar II database, the
LX200-ACF models
offer unmatched state-of-the-art performance.
Note: The LX200 ACF 8", 10", 12" and 14" models are equipped with Series 4000
26mm Super Plössl eyepiece and a 1.25” Diagonal. The LX200 ACF 16" model
is equipped with Series 5000 26mm 5-element Super Plössl eyepiece, 2"
Diagonal and the Zero Image-Shift Microfocuser.
Observe the feather structure of an eagle from 50 yards or study the rings of the
planet Saturn from a distance of 800 million miles. Focus beyond the Solar System on
ancient star clusters, remote galaxies, and stars recently discovered to have planets
orbiting about them. Meade
LX200-ACF telescopes are capable of growing with your
interest and can meet the requirements of the most demanding advanced observer.
B
Eyepiece: Place the Series 4000 26mm Plössl eyepiece into the 90° diagonal
prism (
Pg. 7, Fig. 1, 3) and tighten in place with the eyepiece thumbscrew
( Fig. 1, 2). The eyepiece magnifies the image collected in the optical tube.
C
Eyepiece Thumbscrew: Tightens the eyepiece (Fig. 1, 1) in place. Tighten to a
firm feel only.
D
1 . 2 5 " Diagonal Prism: Provides a more comfortable right angle viewing position.
E
Diagonal Prism Thumbscrew: Tightens the diagonal prism in place. Tighten to
a firm feel only.
F
Rear Cell Port: The Diagonal Prism assembly threads onto this port.
G
Manual Focus Knob: Moves the telescope’s primary mirror in a finely-controlled
motion to achieve image focus. The
LX200-ACF telescopes can be focused on
objects from a distance of about 25 ft. to infinity. Rotate the focus knob
counterclockwise to focus on distant objects, and clockwise to focus on nearby
objects.
H
Fork Arms: This heavy-duty mount holds the optical tube securely in place.
I
Battery Compartments: Insert four user-supplied C-cell batteries into each
compartment (one compartment on each fork arm; eight batteries total).
J
Primary Mirror Lock: Rotate this knob towards the “L o c k” position and adjust the
tension to a firm feel; this action serves to lock in the coarse focus and also to prevent
mirror flop. Use in conjunction with the optional Zero Image-Shift Microfocuser.
1)
Right Ascension (R.A.) Slow-Motion Control: Make fine adjustments in the
Right Ascension,
i.e., the horizontal axis, by turning this control with the R.A. Lock
(see L below) in the unlocked position. Set the R.A. Lock to a “partially locked”
position to create a comfortable drag for the R.A. Slow Motion Control.
Caution: Do not operate the R.A. Slow Motion Control with the R.A. Lock
in the fully locked position, as such operation may result in damage to the
internal gear system and also cause you to lose alignment.

Right Ascension (R.A.) Setting Circle: See APPENDIX A, page 53, for detailed
information.
1@
Right Ascension (R.A.) Lock: Controls the manual horizontal rotation of the
telescope. Turning the R.A. lock counterclockwise unlocks the telescope,
enabling it to be freely rotated by hand about the horizontal axis. Turning the R.A.
lock clockwise locks the telescope, prevents the telescope from being rotated
manually, and engages the horizontal motor drive for AutoStar II operation.
Caution:
Using products other than
standard Meade accessories
may cause damage to the
telescope’s internal
electronics and may void the
Meade warranty.
