LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 2 WARNING! Never use a Meade® LX200®-ACF Telescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope at or near the Sun. Do not look through the telescope or viewfinder as it is moving. Children should always have adult supervision while observing.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 3 CONTENTS Battery Safety Instructions • Always purchase the correct size and grade of battery most suitable for the intended use. • Always replace the whole set of batteries at one time, taking care not to mix old and new ones, or batteries of different types. • Clean the battery contacts and also those of the device prior to battery installation. • Ensure the batteries are installed correctly with regard to polarity (+ and -).
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 4 QUICK-START GUIDE It is recommended that you attach the supplied tripod to the LX200-ACF for observing. Perform the telescope and AutoStar II setup indoors in the light so that you become familiar with the parts and operation before moving the telescope outside into the dark for observing. The setup is the same for the standard and giant field tripods.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 5 Move the spreader bar so that the 3 arms of the spreader bar are lined up with the 3 tripod legs. Place the entire telescope onto the top of the tripod head, and thread the rod into the central threaded hole in the bottom of the drive base of the telescope. Tighten the T-handle tension knob (Fig. A, 3); firm tightening of the tension knob is sufficient to result in rigid positioning of the tripod legs.

LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 15 Choosing an Eyepiece A telescope’s eyepiece magnifies the image formed by the telescope’s main optics. Each eyepiece has a focal length, expressed in millimeters, or “mm”. The smaller the focal length, the higher the magnification. For example: An eyepiece with a focal length of 9mm has a higher magnification than an eyepiece with a focal length of 26mm.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 16 Mounting and Adjusting the Viewfinder To align the viewfinder, perform steps 1 through 5 during the daytime; perform step 6 at night.

LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 17 OBSERVING Important Note: Objects appear upsidedown and reversed left-forright when observed in the viewfinder. Objects viewed through the telescope eyepiece when inserted into the diagonal prism and microfocuser assembly appear right-side-up, but reversed left-for-right. This image inversion is of no consequence when observing astronomical objects and, in fact, all astronomical telescopes yield inverted images.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 18 9. Bring the object into focus (see below). Focusing the Eyepiece Using the Microfocuser (16" Model) The LX200-ACF zero image-shift microfocuser (Pg. 7 Fig. 1, 24) allows you to obtain the most precise image focus possible during visual, photographic, and CCD applications, maintaining precise and “jiggle-free” image centering on even the smallest CCD chips.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 19 Observe the Moon Definition: Initialization is a procedure that ensures that AutoStar II operates correctly. When you first use AutoStar II, it doesn’t yet know where the observation location site is or the time or date of the observation session. During the automatic alignment procedure, the system calculates these parameters automatically.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 20 5. Important Note: Once the telescope is aligned, only use the Arrow keys to move the telescope. Once the telescope has been aligned, do not loosen the telescope locks (Pg. 7, Fig. 1, 12 and 17), or move the base manually, or alignment will be lost. Important Notes: It is recommended that you do not attempt a GPS fix indoors. It is also recommended that you CALIBRATE SENSORS the first time your telescope takes a GPS fix. See page 29 for more information.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Tip: The GO TO key also allows you to perform a “spiral search”. A spiral search is useful when the telescope slews to an object, but that object is not visible in the eyepiece after the telescope finishes its search. (This sometimes occurs during an alignment procedure.) Press GO TO when the telescope stops slewing. The telescope begins to move in a spiral pattern at a very slow speed around the search area.

If the microfocuser is flush against the de-rotator, the assembly will not work properly. This is true also with other accessories that may attach up flush against the de-rotator housing.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 71 APPENDIX I: Smart Mount Introduction Smart Mount improves the pointing accuracy of your LX200-ACF telescope’s “Go To” system. Despite careful efforts to calibrate and align telescopes, they may fail to precisely center objects. Smart Mount allows your telescope to learn about, and then correct for, any systematic pointing errors, regardless of the cause.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Page 72 Permanently Mounted Scopes For permanently mounted telescopes, it is not necessary to have more than one model unless the weight and balance of auxiliary equipment introduces balance or flexure changes that significantly affect pointing. The best practice is to train the Smart Mount and then run a couple of sessions with Update enabled. Thereafter, simply leave Smart Mount On as the installation default.

What he saw, and what he realized about what he saw, has forever changed the way mankind thinks about the universe.
LX-200ACF_0308_REV2.qxd 3/26/09 3:23 PM Tip: Enter a date in the Date menu and you can determine if a planet(s) will be visible during the night of the entered date by checking its rise and set times. Page 75 Planets Planets change positions in the sky as they orbit around the Sun. To locate the planets on a given day or month, consult a monthly astronomy magazine, such as Sky and Telescope or Astronomy. You can also consult AutoStar II for information about planets.
