INTRODUCTION The ETX-LS LightSwitch® 6" ACF and ETX-LS LightSwitch® 6" SC Telescope The most sophisticated and easiest to use telescopes ever Congratulations on receiving your new ETX-LS 6” telescope. You’ll find that this telescope system has all you need to explore the Universe we live in. Meade’s concept was to create a telescope that would be simple enough for anyone to use, yet capable enough for the experienced amateur to stretch their knowledge and skills.
You may want to perform the ETX-LS assembly indoors in the light so that you become familiar with the parts and operation before moving the telescope outside into the dark for observing. This Getting Started Guide assumes you are too impatient to read the entire manual first and want to use your new telescope as quickly as possible. Just follow the simple steps below and you will be up and running before you know it.
Center Hub Follow the battery polarity (orientation) as indicated by molded icons Thumb-Screw 5 Take the ETX-LS from its packaging and place the entire telescope onto the top of the tripod head. Rotate the telescope head slowly until you feel the scope register on the center hub of the tripod head. Carefully screw the three attachment thumb-screws on the bottom of the plate to the base of the tripod. Hand tighten the screws so the telescope cannot spin or wobble on the tripod head.
Your Telescope is now Fully Assembled GETTING STARTED Attaching Accessories Now remove the dust cover from the front of the telescope tube. Be careful not to touch the glass lens. 8 Be sure the telescope master power switch is in the off position. Remove the ETX-LS handbox and the coiled interface cable from the packing materials. Plug one end into the HNDBX port of the control panel and plug the other end into the Handbox port on the ETX-LS handbox.
Focus Knob introductory message. You can press the “MEDIA” key to bypass the introduction if you like. If you have attached a video cable from the Video Out connection on the telescope to the composite video input of a TV monitor, you will also see graphics accompanying the telescope introduction. Slew Speeds: Speed 9: Fast ' ' Speed 5: Medium ' ' Speed 1: Slow Arrow Keys GETTING STARTED After the telescope powers on, you will hear a brief At this point look through the eyepiece of the telescope.
Now that you have successfully setup and used your ETX-LS, it’s time for more information about all the capabilities of this amazing telescope system. The first step is to familiarize yourself with the AutoStar III handbox operation. The largest keys on the keypad are the motion control keys. Most of the time, these keys allow you to move, or slew, your telescope both up and down and right and left. Press them now and see how the telescope moves in response to the keys.
The telescope will now start to tell you the story of Andromeda. You can listen to the whole story, or press the “MEDIA” key to skip the story and more menu choices will appear. If you want to go from the menu, “BACK” to the story, just press the “MEDIA” key again to restart the story. A complete tree of the available menu choice is contained in figure 6 on page 23 of the manual. CHANGING MODES Menu Mode Up till now we have been exploring the Menu Mode.

Adjusting the Red-Dot Finder On/Off & Brightness Adjustment Because your telescope has so much magnification, its field of view is very small. This can make it hard to know exactly where your telescope is pointing by simply looking at it. To help you point the telescope quickly and accurately, for terrstrial targets or when not using Auto Alignment and GO TO pointing, the ETX-LS has a 1X Red-Dot Viewfinder. The Red-Dot Finder will aid you in pointing your telescope easily.
Meade makes a complete line of accessories to enable you to get the most fun and performance from your ETXLS telescope. No matter what you want to accomplish, we have the equipment to help you get there. Choosing Eyepieces 26mm eyepiece, which gives a wide 53 ARC Minute (just a little less than 1 degree) field of view with 59x magnification.

When the GPS is disabled, you are presented a menu that offers you the choice of using the previous locations, and the internal clock time, entering the date, time and location manually, taking a GPS fix, or starting in a Demo/Terrestrial mode. • Rev.
Two Star Alt Az Alignment e. “Automatic Alignment: Selecting Star” and “Slewing” display. When it is close to the alignment star “Center Brightest Star: Press “ENTER”” displays. When the telescope slews to the first star, it may not appear in the field of view in the eyepiece. Use the Red Dot Finder (Pg. 12, Fig. 2, 16) to locate the star. The alignment star will be easy to recognize — it will be the brightest star in the area of the sky where the telescope is pointing.
One-Star Alignment requires some knowledge of the night sky. ETX-LS provides a library of bright stars. One-Star Alignment is identical to Two-Star Alt/Az: Alignment (see TWO-STAR ALT/AZ ALIGNMENT above), except only one star from the database is chosen by the observer for alignment. Finding Objects Not in the Database Although ETX-LS contains an extensive database of celestial objects (stars, nebulae, planets, etc.
“Center Landmark. Press “ENTER”” displays. Using only the Arrow keys (do not manually move the telescope), move the telescope to the desired landmark and center the object in the eyepiece. Press “ENTER”. The object is now stored in memory. 9. “Landmark: Add” displays. If you wish to add more landmarks, repeat steps 5 through 7. To view a landmark in the database 1. Make sure the telescope is located and aligned exactly as when the desired landmark was entered into memory. 2.
The ETX-LS is an excellent high-resolution, terrestrial (land) telescopes. Viewing terrestrial objects requires looking along the Earth’s surface through heat waves. These heat waves often cause degradation of image quality. Lower power eyepieces, like the Super Plössl 26mm eyepiece, magnify these heat waves less than higher power eyepieces. Therefore, lower power eyepieces provide a steadier, higher quality image.
The ETX-LS is a precision optical instrument designed to yield a lifetime of rewarding viewing. Given the care and respect due any precision instrument, the ETX-LS will rarely, if ever, require factory servicing. Maintenance guidelines include: 1. Avoid cleaning the telescope’s optics: a little dust on the front surface of the telescope’s correcting lens causes virtually no degradation of image quality and should not be considered reason to clean the lens. 2.
Follow these optical system: steps for collimation of the 1. The only adjustments possible, or necessary, on the ETX-LS are from the three inner most screws Collimation Screws eyepiece field of view (Fig. 8, 2), in the same direction as the darker shadow is offset in the ring of light. 4. Turn the set screw that you found with the pointing exercise while looking in the eyepiece. You will notice that the star image will move across the field.
A Note About the “Flashlight Test”: If a flashlight or other high-intensity light source is pointed down the main telescope tube, the view (depending upon the observer’s line of sight and the angle of the light) may reveal what appears to be scratches, dark or bright spots, or just generally uneven coatings, giving the appearance of poor quality optics.
Your ETX-LS telescope comes with a “Mini SD Card” slot located in the front edge of the fork arm. With a user supplied “Mini SD Card” or a “Micro SD Card” in a Mini Card Holder, you can update your telescope firmware or save images made with the ECLIPS CCD. Only use SD Cards bearing the official SD logo. Each card must be properly formatted, using a PC utility or AutoStar Suite, before use in the ETX-LS. The card must be formatted with the FAT32 File System.
TRAINING THE DRIVE APPENDIX A: TRAINING THE DRIVE Perform this procedure if you are experiencing any pointing accuracy problems. Fig. 9 depicts the complete Drive Training procedure. NOTE: Use a terrestrial object, such as a telephone pole or lamp post, to train the drive. Complete this exercise once every 3 to 6 months.
CREATING USER OBJECTS and TOURS User Object are catalogs of deep sky objects you can create or import that are not in the ETX-LS telescope. You can define your own objects and create your own titles. Tours, similar to the three preloaded guided tours (Tonight’s Best”, “A Star’s Life” and “How Far Is Far”), can also created. You can chose your own theme and objects.
BASIC ASTRONOMY In the early 17th century Italian Scientist Galileo, using a crude telescope considerably smaller than the ETXLS, turned it to look towards the sky instead of distant trees and mountains. What he saw, and what he realized about what he saw, forever changed the way mankind thought of the universe.
Mars is about half the diameter of Earth, and appears through the telescope as a tiny reddish-orange disk. It may be possible to see a hint of white at one of the planet’s Polar ice caps. Approximately every two years, when Mars is closest to Earth in its orbit, additional detail and coloring on the planet’s surface may be visible. Jupiter is the largest planet in our solar system and is 11 times the diameter of Earth. The planet appears as a disk with dark lines stretching across the surface.
