Hand Control Guide

Before you can begin using your NexStar 80SLT, you must setup your computerized hand control and go through the SkyAlign alignment procedure. In order for the NexStar to accurately point to the objects in the sky, it must first be aligned with known positions (stars) in the sky. With this information, the telescope can create a model of the sky, which it uses to locate any object in its database

Use the hand control direction arrow buttons to point telescope at a distant land object, like a telephone pole or at night you can use the moon. Center and focus the object in the 25mm eyepiece of the telescope.

In order to accurately center an object in the eyepiece it may be necessary to change the slew speed of the motors. To change the slew speed, press the RATE button then select a number from 1 (slowest) to 9 (fastest).

With the object centered in the eyepiece, use the azimuth (right/left) and altitude (up/down) adjustment knobs on the finderscope to place the red alignment dot directly over the centered object.
