Do not look through a telescope or its viewfinder as it is moving. Children should always have adult supervision while observing.

Introduction

This manual describes applications of the Autostar Computer Controller with various models of Meade telescopes: ETX-90EC: Refer to the manual included with the ETX-90EC for instructions on the basic operation of the telescope, including usage of the standard-equipment Electronic Controller (EC). DS-telescopes (e.g., DS-60, DS-70, etc.): (a) Refer to the manual included with each of these models for instructions on the basic operation of the telescope. (b) If you purchased a DS-model which includes the #492 Dual-Motor Electronic Control System, then interchange the Electronic Controller (EC) of the #492 System with the Autostar Computer Controller and follow the instructions in this manual. The Autostar handbox plugs into the same HBX connector on the telescope as the EC handbox. (c) If your DS-model did not originally include the #492 System, and you are now adding the complete #493 Autostar Computer Control System (including motors on both axes) to your telescope, then read the enclosed manual (Meade #493 Autostar Computer Control System) first, before reading this manual. Autostar assists the observer with a large variety of features, including: Control the movement of the telescope to locate terrestrial and astronomical objects. Catalog of events (e.g., Moon phases, meteor showers, etc.).

-3 Guided tours of the best objects based on date and location. Model #495 Autostar has a database of over 1,200 astronomical objects. Model #497 Autostars database includes over 12,000 astronomical objects. A glossary of over 90 descriptions and definitions. A built in Help function by pressing the ? key. Utilities including eyepiece magnification, alarms, battery monitor, power saving functions, and more. Connect to a computer to remotely control the telescope. Language Selection: Autostar offers text in one of six possible languages. Press the key for the desired language. *Problem* If the wrong language is selected, press MODE and Autostar requests the language selection again. Sun Warning: Autostar displays a sun warning message which must be carefully read by every person using the telescope. After reading the message, follow the instructions to move to the next operation. *Hint* If screen messages are moving too fast (or slow), use the SCROLL keys (8 & 9) to change the speed. Self Calibration: Testing Motors is displayed and the telescope moves a short distance in both axes. Automatic calibration of the motors happens only once, the first time Autostar is used. NOTE: If Autostar is moved to another telescope, it needs to be recalibrated (see the Setup:Telescope:Calibrate Motor menu). Getting Started: Getting Started, is displayed with a message offering a description of Autostar operation. Press ENTER (2) to bypass this tutorial or press the ? key (10) to begin the message. At this point, Autostar can move the telescope using the ARROW keys (5). Pressing one of these keys moves the telescope up, down, left, or right. The speed of movement is changed by pressing a NUMBER key (9 = fastest, 1 = slowest). Date: The date must be entered each time power is applied. Enter numbers by pressing the numeric keys. Press the right or left ARROW key (5) to move the cursor. To change the month, use the up or down ARROW key. After the correct month is displayed press the right ARROW key to move to the year. Change the year, if required, using the numeric keys. When the correct date is displayed, press ENTER to complete the date entry. *Hint* The utility light (14) is turned on during date and time entry to illuminate a watch. Time: Local time must be entered each time Autostar power is applied. Enter the time using the NUMBER and ARROW keys. Change AM or PM using the SCROLL keys (8 & 9). When the time displayed is correct, press ENTER to start the clock running.
This Instruction Manual begins by explaining the operation of Autostar in sequence from turning on power to locating the first object in the sky. The telescope and manual should be used together to complete this important series of operations. The balance of the manual is a reference for additional functions. The first time Autostar power is applied, additional activities are required. Pick a comfortable location and take the time necessary to read each step carefully. When viewing is required, move to an open area outside and continue operation.

First Operation

Autostar Installation: Verify that power is turned off at the telescope computer control panel. Plug the coil cord (13) into the coil cord port (11). Plug the other end into the computer control panel HBX (handbox) port. Turn on the telescope power using the switch on the ETX computer control panel or by plugging in the power cord to the DS computer control panel. Initialization: With power on, Autostar begins the startup process by displaying the Meade copyright message, sounding a beep, and initializing the computer system. After initialization, Autostar requests information needed to operate the telescope. *Problem* If Autostar does not display messages, turn the power off and then back on. Also, check the batteries or other power source. If the beep sounded and the screen is difficult to read, press MODE (3) and Autostar resets the screen to factory settings.
-4Daylight Savings: When time is entered, it must be identified as Standard or Daylight Savings. Daylight Savings is when clocks are set ahead one hour. If Daylight Savings, select YES, otherwise choose NO. Use the SCROLL keys (8 & 9) to chose YES or NO. When the screen is correct, press ENTER to complete the entry. Telescope Site: The location on Earth (site) of the telescope must be entered. Use the SCROLL keys to pick the nearest Country (or State) from the alphabetical list. When the screen shows the correct selection, press ENTER. Next use the SCROLL keys to select the nearest City. Press ENTER when the best choice is displayed. NOTE: Not all countries or cities are listed. Pick the nearest from available choices. To add more sites, see the Setup:Site:Add menu. Telescope Model: Use the SCROLL keys to display the telescope model, then press ENTER. The telescope model can be found on the telescope box or a foil label on the telescope tube. Autostar automatically requests this information only once. Autostar Initialization Complete: In future sessions, Autostar only requests the date and time during the power-on sequence. Other items (such as language, motor calibration, site, and telescope model) remain unchanged from the previous session. After initializing, Autostar pauses at the alignment menu. Alignment relates objects in the sky to the position of the telescope. Autostar needs to be aligned accurately to find objects. Before proceeding with alignment, a general explanation of Autostar functions is helpful. Keypad and Help Function: The Autostar keypad has 20 keys. To register a single keystroke, press and release a key firmly and briefly. Holding a key for a longer period causes a repeated key entry. This is useful for operations which require multiple keystrokes. The Help (?) key (10), provides advice on operations, in the form of a moving message. LCD Screen and Hypertext: The Autostar screen has 2 lines of 16 characters each. The top line is the current active function or menu and the bottom line is the next level of options, data, or a message. When a moving message appears the speed can be changed using the SCROLL keys. To exit the message, press MODE briefly, unless the message gives some other instruction. Sometimes embedded in a moving message is a bracketed [word], referred to as Hypertext. Autostar Hypertext is similar to that used on the Internet. While a Hypertext word is visible, press ENTER, and the definition of the word appears, replacing the first message. After the new message is complete, press MODE and return to the original message. If the Hypertext is an object, like Jupiter, press GO TO while the word is visible and the telescope moves and points at the object.

Autostar Menus

Autostar Menu Structures: Autostar has menus with lists of available features (see Figure 1). The menus are organized in descending levels and are seen on the Autostar screen (1). The top line of the screen is the currently active menu category and the bottom line has the list of menu options that can be selected. Four keys are used to navigate the menus; ENTER, MODE, and both SCROLL keys. Pressing ENTER activates the item listed on the bottom line (moving down a menu level) and moves it to the top line. With the selected function on the top line, a new list of functions can then be displayed on the bottom line. To go back to the previous menu (moving up a menu level), press MODE. Pressing a SCROLL key changes the menu item visible on the bottom line. Since only one item of a menu list can be displayed on the bottom line, scrolling makes the other choices visible.
Autostar Manual Operation
Moving the Telescope: The ARROW keys (5) move the telescope in four directions; up, down, left, and right. The speed of movement is changed by pressing a numeric key from 1 to 9, with 9 being the fastest. Speed settings remain until changed by pressing a different number. Take time now to move the telescope using the ARROW keys. Pick an object and point the telescope at it. Use a slower speed when nearing the object to accurately center it in the viewfinder and then in the eyepiece. These skills are useful when training and aligning the telescope.

-6Figure 1 shows the complete Autostar menu structure showing the paths that can be followed. From any point in the menu, pressing ENTER moves along a menu line to the right. Pressing MODE moves to the left along a menu line. Pressing the down SCROLL key moves down menu lists and pressing the up SCROLL key moves up. Menu Example: Finding the sunset time is a good example of how to use Autostar menus. Begin by pressing MODE several times until the screen reads Select Item: on the top line and Object on the bottom line. Pressing MODE multiple times causes Autostar to move back to the Object menu. The main menu has six choices; Object, Event, Guided Tour, Glossary, Utilities, and Setup. Pressing a SCROLL keys makes each of these visible on the bottom line of the screen. Press a SCROLL key until the bottom line reads, Event, then press ENTER to select that menu. The top line now reads Event: and the bottom line reads, Sunrise (the first item in the Event menu). Use a SCROLL key to view the other items, finishing with Sunset on the bottom line. Press ENTER to start the sunset calculation which then displays the sunset time for the current day. To leave the Sunset function and return to the Event menu, press MODE. Press MODE again to return to the main menu with the top line reading, Select Item: and the bottom line Event. Use similar sequences of the ENTER, MODE and SCROLL keys to explore other functions in the Autostar menu. Try other events or look up words in the Glossary. Do not change any settings in the Utilities or Setup menus until they have been explained later in this manual. *Hint* To avoid changing any value, press MODE which returns to the previous menu without making a change to any Autostar settings. Also use the Help (?) key for an explanation of any menu. To train Autostar, prepare the telescope for optical viewing by removing dust covers and inserting an eyepiece. The viewfinder should also be aligned and ready for use. Select a fixed land object as a reference for the training process. Point the telescope at the selected object and center it in the eyepiece. Press MODE until the main menu is displayed (Select Item:). Press a SCROLL key until Setup is on the bottom line, then press ENTER. With Setup: now on the top line, press a SCROLL key until the bottom line reads Telescope, then press ENTER. In the Telescope menu, press a SCROLL key until Train Drive appears on the bottom line, then press ENTER. The top line of the screen should read, Train Drive: and the bottom line should read Az. Train. Both telescope motors need to be trained separately. Start with Az. Train by pressing ENTER and following the instructions given. Autostar moves the telescope away from the centered object and asks that it be centered using only one ARROW key (all other ARROW keys are disabled). After the object is centered, press ENTER. Autostar now moves the telescope in the other direction and ask for the object to be centered again. Center the object and press ENTER. The training for the Azimuth axis is complete. Autostar has returned to the Train Drive: menu. Select the second motor using a SCROLL key until the bottom line reads, Alt. Train. Press ENTER and follow instructions as before. This time, the telescope moves up and down otherwise the training sequence is the same as Az. Train. After completing Alt. Train, Autostar is ready for alignment and operation. Remember the accuracy of this training determines how well Autostar finds objects.

Telescope Alignment

Alignment is the method used to relate objects in the sky to the position of the telescope. Autostar has six methods of alignment, three for Polar alignment and three for Alt/Az Alignment. The simplest method to align is Easy Align in the Alt/Az mode. Easy Align requires the telescope to be placed level on a table or on a tripod such as the Meade Deluxe Field Tripod. Select an

Telescope Training

Autostar is not able to accurately point at objects unless it is aligned and trained. Training Autostar allows it to collect data about the gears in the telescope motor system. Once training is complete, Autostar saves the data for later operations. Use great care in training the Autostar system to achieve maximum accuracy.
-7outside area with few obstructions and an open sky. The telescope should be prepared for observing with lens covers removed, a low power eyepiece installed and the viewfinder aligned. Use MODE to return to the main menu (Select Item:). Chose the Setup menu and press ENTER. Press ENTER again to select the Align menu. Press ENTER a third time to begin the Easy Align procedure and follow the instructions given by Autostar. The first action is to put the telescope in the Home position. Home position for all telescope models is with the telescope tube level (at 0) and pointed North. ETX telescopes must also have the base in a special position to avoid internal hardstops. Begin by releasing the ETX horizontal lock lever. Turn the telescope counterclockwise until it stops. Next turn the telescope clockwise until the fork arm is directly over the computer control panel and lock the horizontal axis. With the telescope in the home position (level and pointed North), press ENTER. Autostar now selects a bright star and moves the telescope to point near it. Using the ARROW keys, center the star in the viewfinder and then in the eyepiece. The alignment star should be easily recognized and is the brightest object in the sky where the telescope is aimed. When the star is centered, press ENTER. Autostar then selects a second star and points the telescope toward it. Repeat the same procedure as used on the first star. If the alignment operation was done accurately, Autostar displays, Align Successful. The telescope begins tracking (motors can be heard making a low hum) and the screen returns to the main menu. *Hint* If a selected star is not visible or is behind an obstacle, press a SCROLL key and Autostar makes another selection. The SCROLL key can be pressed as often as needed to locate a visible star. *Problem* If Autostar detects inconsistent data the screen reads: Alignment Failed. Repeat the alignment procedure until successful. Guided Tour picks the best objects available for viewing. To start a guided tour, select the Guided Tour function from the main menu. Use the SCROLL keys to view the list of tour objects and press ENTER to select any object of interest. When selected, the object name appears on the top line and information about the object is on the bottom line. Object information includes: astronomical coordinates, size, brightness, and more. All information can be seen using the SCROLL keys. Some objects have a moving message with a description of the object. If a moving message appears, use MODE to exit the message when completed. To direct Autostar to point the telescope at a selected object, press GO TO. The telescope moves at high speed toward the object. The telescope slows as it approaches the object and eventually stops and sounds a beep. The object should be visible in the eyepiece of the telescope. To see more objects in the Guided Tour, press MODE. Display a new object with the SCROLL keys and press ENTER to select it. Use this method to view any of the Guided Tour objects. *Problem* If objects are not in the eyepiece after GO TO is pressed, check the viewfinder to see if it is near the center. Under high magnification, some objects may be slightly out of the field of view and need some minor manual correction using the ARROW keys. If the object was not close to center, there are several possibilities. First, the telescope must sit on a stable surface or tripod. Second, use only the ARROW keys or GO TO key to move the telescope or alignment is lost. Third, be sure the date, time, and site are accurately entered. Fourth, make sure the telescope axis locks are firmly engaged to prevent slippage of the internal clutch. Fifth, telescope training must be accurate. Repeat very carefully all of the steps to train the telescope. Last, the alignment procedure must be done accurately. Make sure each step is done carefully and that alignment stars are centered. Synchronize Function: To improve the ability of Autostar to find objects, a sync function is included to make minor alignment corrections. If an object is not centered in the eyepiece, press and

Finding Objects in the Sky
With Autostar aligned, it is possible to find any visible object in the Object menu. Another option, is to take a Guided Tour.
-8hold ENTER for two seconds. Autostar requests that the selected object be centered, then press ENTER again. This improves the accuracy of alignment, particularly in the region of sky immediately around the sync object. Telescope Status Display: This is activated by pressing MODE for more than 2 seconds. The screen shows values related to Autostar operation, and can be viewed by using the SCROLL keys. The telescope can also be pointed at a particular location using the ARROW keys and watching a location display. For automatic movement of the telescope, press GO TO during a location display. Autostar requests the destination coordinates to be entered. Enter the coordinates, then press ENTER. Autostar moves the telescope to that location. To exit the status display, press MODE. Deep Sky is a database of objects outside our solar system such as nebulae, star clusters, galaxies, and quasars. Star is a database of stars by different categories such as named, double, variable, or nearby. Satellite is a database of Earth-orbiting objects such as the International Space Station, the Hubble Space Telescope, and other satellites. This feature is recommended for advanced users only since acquiring and tracking a fast moving object can be complicated. Additionally, Autostar needs fresh satellite data or it is unable to accurately predict the appearance time and location. The Meade web site (www.meade.com) provides updated information on orbits and complete instructions on how to use this feature. User Objects allows the user to define deep-sky objects of interest that are not currently in the Autostar database. Landmarks stores terrestrial points of interest. To enter a new landmark the telescope must be located and aligned exactly as when other landmarks were entered. Sync on a reference landmark, then move the telescope to the new landmark and enter it into the Autostar database. Identify is used when an object is placed in the telescope eyepiece and Autostar identifies the object being observed. B. Event Menu Options The Select Item: Event menu provides access to dates and times of astronomical events. Included are: Sunrise and Sunset displays the time that the Sun rises or sets on the current date. Moonrise and Moonset displays the time that the Moon rises or sets on the current date. Moon Phases displays the date and time of Full, New, 1st Qtr, and 3rd Qtr Moon. Meteor Showers provides information about upcoming meteor showers, including dates of the shower and when it is scheduled to reach maximum.

Autostar Menus and Function Reference
This section discusses each of the Autostar menus and functions (see Figure 1). To access any of the functions use the ENTER, MODE and SCROLL keys as in previous operations. A. Object Menu Options The Select Item: Object menu contains a database of objects for viewing, including astronomical, terrestrial and user-defined objects. When an object has been selected it appears on the top line of the screen. The bottom line contains information about the object which is viewed using the SCROLL keys. Press GO TO and the telescope points at the current object. Solar System includes eight planets (Earth is not included) in order out from the Sun, followed by the Moon, asteroids, and comets. Constellation is a database of all 88 northern and southern hemisphere constellations. When this menu option is chosen and a constellation name appears on the first line of the screen, pressing GO TO changes the second line to the name of the brightest star in the constellation. Pressing GO TO again moves the telescope to that star. Use the SCROLL keys to cycle through the stars in the constellation from brightest to dimmest.
-9 Solar Eclipse lists upcoming Solar Eclipses, including the date and type of eclipse along with the location and time of the first and last contacts of the lunar shadow across the Earth. Lunar Eclipse lists upcoming Lunar Eclipses. Min. (Minimum) of Algol is the minimum brightness of the eclipsing binary star system, Algol. Every 2.8 days during a 10 hour period, Algol undergoes a major change in magnitude as one of the two stars passes behind the other. The combined magnitude of the two stars dips from +2.1 to a minimum of +3.4 halfway through the eclipse as the second star is hidden. Autumn and Vernal Equinox calculates fall or spring equinox. Winter and Summer Solstice calculates the winter or summer solstice for the current year. C. Glossary Menu Options The Select Item: Glossary menu provides an alphabetical listing of definitions and descriptions for common astronomical terms and Autostar functions. Press ENTER to access the Glossary database. Use the SCROLL keys to scroll through the alphabet. Press ENTER on the desired letter. Scroll to the desired entry, then press ENTER to read the description. D. Utilities Menu Options The Select Item: Utilities menu provides access to several extra features within Autostar, including a countdown timer and an alarm. Specific Utilities options include: Timer selects a countdown timer. This feature is useful for things such as astrophotography and in tracking satellites. To use the Timer, press ENTER, then choose Set or Start/Stop. Alarm selects a time for an alarm signal as a reminder function. To use the Alarm, press ENTER, then choose Set or Start/Stop. Eyepiece Calc calculates information about an eyepiece and how it functions for the specific telescope to which Autostar is connected. Brightness Adj uses the scroll keys to adjust the brightness of the screen. When complete, press ENTER. Contrast Adj uses the scroll keys to adjust the contrast of the screen. This feature is usually only required in very cold weather. When complete, press ENTER. Battery Alarm sounds when the batteries are nearing replacement. If not desired, press the scroll key to change the screen from YES to NO. Press ENTER and the beep no longer sounds. Landmark Survey automatically moves the telescope to all userdefined landmarks with a pause at each location. Use the ARROW keys to manually locate the first landmark. Press and hold ENTER for 2 seconds; the message ENTER to Sync. appears. Press ENTER and this landmark is synchronized with all other landmarks. Important Note: To accomplish a landmark survey, all landmarks must have been entered into the Autostar database from the same reference point (i.e., the telescope must be in the exact same location and mounted and aligned in the exact same way). Sleep Scope is a power saving option that shuts down Autostar and the telescope without forgetting its alignment. Press ENTER to activate the Sleep function and Autostar goes dark but the internal clock keeps running. Press any key, except ENTER, to re-activate. Park Scope is designed for a telescope that is not moved between observing sessions. Align the telescope one time, then use this function to park the telescope. Next time it is powered up, enter the correct date and time no alignment is required. Pressing ENTER causes the telescope to move to its pre-determined Park position. Once parked, the screen prompts to turn off power. E. Setup Menu Options The Select Item: Setup category primary function is to align the telescope. However, there are numerous other features available within Setup. These options are: Date changes the date currently used by Autostar. Time changes the time entered into Autostar. Setting the correct time is critical for Autostar to properly calculate locations and events.

- 10 Daylight Saving is used to set the status of Daylight Savings time. Telescope accesses the telescope options, including: Telescope Model: Selects the model of telescope connected. Focal Length: Changes the focal length of the telescope by typing in new numbers, then press ENTER. Az Ratio and Alt Ratio: The Az (Azimuth) ratio and Alt (Altitude) ratio refers to the gears installed in the telescope motors. Do not alter these numbers. Mount: Choose between Alt/Az mount or Polar Mount. A polar mount requires that the telescope be physically polar aligned. Train Drive: Trains the telescope motor drive to locate objects with more precision. This function is very important to accomplish the first time Autostar is connected to a telescope. Tracking Rate: Changes the speed at which the telescope tracks targets in the sky. Sidereal is the rate that stars move across the sky due to the Earths rotation, Lunar is the rate that the Moon moves, and Custom allows entry of userdefined tracking rates. Reverse L/R: Reverses the functions of the left and right arrows (i.e., the right key moves the telescope to the left). Reverse UP/DOWN: Reverses the functions of the up and down arrows (i.e., the up key moves the telescope down). slews to a nearby bright star and requests ENTER to Sync. Center the star in the eyepiece, then press ENTER. The telescope then slews to the originally requested object. Targets switches between Astronomical targets (motor drive on) and Terrestrial targets (motor drive off). Site allows access to the Site options including: Select: Displays the current site chosen during initialization. Use the scroll keys to cycle through all available sites. Add: Adds a new observing site. Delete: Deletes a stored site. Edit: Edits a selected site, including: the name, latitude, longitude, and time zone.
Owner Info accesses the owner information menu, including the owners name and address. Clone uploads information from one Autostar to another. Three options are available: Catalogs: Sends only the user-defined object information, such as new satellite or comet information, to another Autostar. Software: Sends only the basic Autostar software. This is useful if one user has downloaded a new version of the Autostar software from the Meade website (www.meade.com) and wants to pass this new software along to friends. All: Everything is sent to another Autostar.
NOTE: The reverse functions above are useful for observers in the southern hemisphere (i.e., South America, Australia, Africa, etc.) Calibrate Motor: If the telescope motors appear to have any sort of problem, use this option to retest the motors before doing a Reset. This option is also used if Autostar is moved between telescopes to match Autostar to the telescope. High Precision: If High Precision is turned on, when looking for a faint celestial object (i.e., a nebula or galaxy) Autostar

Meade #1244 Electric Focuser
For use with ETX-90 and ETX-105 Telescopes
The Meade #1244 Electric Focuser rapidly focuses eyepiece images in all ETX-90 and ETX105 telescope models. The #1244 includes coarse and microfine speeds. The standard-equipment focuser 3-button hand controller accepts one usersupplied 9-volt battery. If used with an ETX-EC Astro Telescope, the focuser functions are controlled directly with either the Electronic Controller (standard with the ETX90EC or ETX-105EC) or with the optional #497 Autostar Computer Controller, rather than with the Focuser 3-button hand controller. PARTS LIST When opening the packing box for the first time, carefully note the following parts: Electric focuser gearbox with attached coiled cord Electric focuser 3-button hand controller Packed in a poly bag: 1.75-long hex-head screw 1 diameter brass focusing gear Mounting plate Hex-wrench set (3 wrenches) INSTALLATION To attach the #1244 Focuser to the telescope: 1. Use the medium hex-wrench to remove the hex-head screw (1, Fig. 1) from the rear cell of the telescope. The screw is located above and slightly to the left of the focus knob (2, Fig. 1). 2. Use the small hex-wrench to loosen the set screw on the telescopes focus knob (2, Fig. 1); remove the knob. NOTE: Do not discard the hex-head screw removed in step 1 or the focus knob removed in step 2. If the #1244 Focuser is ever removed, these items must be reinstalled on the telescope. 3. Slide the center hole of the mounting plate (2, Fig. 2) over the focus shaft, so that the flat side faces the body of the telescope and the upper hole is aligned with the hole from which the hex-head screw was removed in step 1.

4. Place the focusing gear (1, Fig. 2) on the focus shaft (3, Fig. 2) so that the hub of the gear faces the body of the telescope and the gear is approximately flush with the rear of the shaft. Tighten the set screw on the focusing gear with the small hex-wrench. 5. Carefully place the electric focuser gearbox (4, Fig. 2) over the focusing gear. To orient the gearbox, the attached coiled cord should be on top. Slide the gearbox shaft into the hole from which the hex-head screw was removed in step 1. The focusing gear (1, Fig. 2) fits into the round slot in the gearbox.
6. Place the 1.75-long hex-head screw (5, Fig. 2) into the hole in the rear of the focuser gearbox. Tighten the screw to a firm-feel only using the large hex-wrench. 7. Insert one user-supplied 9-volt battery into the compartment on the rear of the hand controller. Plug the coiled cord of the gearbox into the hand controller. The focuser is now ready for operation. OPERATION The #1244 Electric Focuser may be used with the standard-equipment 3-button hand controller, with the Electronic Controller handbox that is included as standard equipment with the ETX-90EC or ETX-105EC, or with the optional #497 Autostar Computer Controller. See the appropriate controller below for details. NOTE: If using the Electronic Controller or the Autostar Controller, detach the coiled cord from the focuser 3-button hand controller and plug it into one of the AUX ports of the telescopes Computer Control Panel. Flip the power switch to ON. Electric Focuser Controller: The hand controller has two speeds of operation: coarse and microfine. Press the SPEED key to change the focus speed. The Left Arrow moves the focus out and the Right Arrow moves the focus in.
Electronic Controller: After power is applied, the four LEDs flicker. Press any button so that only one light remains lit. Press the SPEED key to switch between the four available focus speeds. The focus speed is indicated by the four lights: the top LED is fastest and the bottom LED is slowest. Press IN and OUT to move the focus in or out. Autostar Computer Controller: After power is applied and Autostar has been initialized (see the Autostar instruction manual), press and hold MODE for two seconds. The Focus menu displays. Press one of the Number keys to change the focus speed: 1, 3, 6, 8, 2: 4, 5: 7: 9: slow moderate medium fast

The Down Arrow moves the focus out and the Up Arrow moves the focus in. Press MODE to exit the Focus menu.
