Alignment Procedure In order for the LCM LCM will automatically select and slew to a second star for alignment. Two-Star Alignment requires the user to identify and manually slew the telescope - Celestron 114LCM Computerized Telescope | LCM Series Manual (English) - Page 11

Each rate corresponds to a number on the hand - Celestron 114LCM Computerized Telescope | LCM Series Manual (English) - Page 15

The LCM will remember these values and use them each time it set the slew limits to 90º in altitude. This will allow the telescope to slew to any object above - Celestron 114LCM Computerized Telescope | LCM Series Manual (English) - Page 16
