See Filter Limits in the Utility Feature section of the manual for more information on setting the filter limits. Caution: Never slew the telescope when someone is - Celestron NexStar 130SLT Computerized Telescope | NexStar SLT Series Manual - Page 20

Note: The EQ North and EQ South tracking modes are only needed with telescopes that can be polar aligned. The NexStar SLT series are exclusively Alt-Az mounted telescopes - Celestron NexStar 130SLT Computerized Telescope | NexStar SLT Series Manual - Page 21
Tracking Rate - In addition to being able to move the telescope with the hand control buttons, the NexStar will continually track a celestial object as it moves across the night sky. The tracking rate can be changed depending on what type of object is - Celestron NexStar 130SLT Computerized Telescope | NexStar SLT Series Manual - Page 22
