8. "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. Display the "Landmark: Select" menu option. Press "ENTER". 3. Use the Scroll keys to scroll through the list of objects you have previously entered. When the desired object displays, press "ENTER" to select the object. Use the Scroll keys to scroll through location information about the object, if desired. Press "GO TO" to slew the telescope to the landmark. 4. Press "BACK" to exit. Observing Satellites In this procedure, you will prepare your telescope to observe a satellite pass. 1. Navigate to the "Object: Satellite" menu option and press "ENTER". 2. Use the Scroll keys to scroll through the list of satellites. 3. Select a satellite from list and press "ENTER". 4. "Calculating..." and then "Tracking..." displays. If the satellite is going to make a pass, "Located" displays. 5. Use the Scroll keys to display data about the pass: aos - acquisition of signal and los - loss of signal. If you subtract the aos from the los, you can calculate how long the satellite will be visible. Location information also displays. 6. "Alarm" displays after the location information. Press "ENTER" and LS automatically sets the alarm to sound a minute before the satellite's scheduled appearance. You may return to regular observations until the alarm goes off. 7. When the alarm goes off, return to the Satellite menu and press a Scroll key until the desired satellite is on the top line of the display. 8. Press "GO TO", LS slews the telescope to where the satellite should appear. The motor drive stops and a countdown is displayed. NOTE: If the scheduled appearance position of the satellite is obstructed (i.e., by a building, tree, or hill), press "ENTER" and LS starts to move the telescope along the expected satellite track. When the track clears the obstruction, press "ENTER" again to pause the telescope, then continue with this procedure. 9. With about 20 seconds left on the countdown timer, start watching through the telescope Red Dot Finder (Pg. 12, Fig. 2, 16) for the satellite to enter the field of view. 10. When the satellite enters the viewfinder field of view, press "ENTER". The telescope starts to track with the satellite. 11. Use the LS Arrow keys to center the object in the viewfinder, then look through the eyepiece to view the object. Satellite orbits change and new satellites (including the Space Shuttle) are launched. You can use the AutoStar Updater program approximately once a month to get updated information and instructions on how to download this data to LS. If orbital parameters are more than one month old, the satellite pass may not happen at the time predicted by LS. Downloading requires you use a USB cable to connect the telescope to a PC to update the satellite elements. NOTE: Satellite observing is an exciting challenge. Most satellites are in low orbit, traveling at approximately 17,500 mph. When visible, they move quickly across the sky and are only in the field of view for a few minutes, requiring LS to slew the telescope rapidly. Best viewing is near sunrise or sunset when the sky is dark. Viewing in the middle of the night can be problematic because the satellite may pass overhead, in the Earth's shadow.
