Once the LX80 is fully assembled and AudioStar initialized, you will need to set the telescope into the home position, and perform an alignment on the night sky in order for the LX80 to successfully locate and track celestial objects. Performing the “Easy Alignment” routine is the ideal way to get started.

1.It is best to start with the mount pointing North as this will simplify the setup. On the front of the mount, line up the North arrow so it points toward either True North or Magnetic North (Page 11, Fig 5, 36). If in the Southern Hemisphere, point the front of the mount True South or Magnetic South.

Note: To locate True North or Magnetic North, see “Finding True North” or “Finding Magnetic North” below.

2.Level the mount, if necessary, by adjusting the length of the three tripod legs or adjusting the fine leg levelers located at the top of each tripod leg.

3.Unlock the RA Lock (Page 8, fig 1, 29). Rotate the Optical Tube Assembly until the “AZ” arrow lines up with the “AZ/EQ” arrow on the base, as shown in Page 28, Fig 34.

Finding True North

Method #1: Finding True North using the North

Star (Polaris): To find True North, insert the bubble level/compass into the accessory adapter and point the telescope tube towards Magnetic North. See the “Locating Polaris” diagram below, which directs you to the North Star (Polaris). Looking towards Magnetic North locate the Big Dipper; follow the two stars in the bowl of the Big Dipper to the North Star. With the tube
