This section describes the basic hand control procedures needed to operate the NexStar. These procedures are grouped into
three categories: Alignment, Setup and Utilities. The alignment section deals with the initial telescope alignment as well as
finding objects in the sk ; the setup section discusses changing parameters such as tracking mode and tracking rate; finally,
the last section reviews all of the utilities functions such as the RS-232 connection, activating the cord wrap feature and
backlash compensation.

In order for the NexStar to accurately point to objects in the sky, it must first be aligned to two 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 with known
coordinates. There are two ways to align the NexStar with the sky depending on what information the user is able to
provide. If you know the names of two bright, visible stars in the sky, you can use the two-star alignment method; if you
do not know the names of two stars in the sky, you can enter the longitude and latitude (provided in Appendix C) of your
observing location and NexStar will auto-align itself to two stars in the sky for you.

With the two-star alignment method, the NexStar requires the user to know the positions of only two bright stars in order to
accurately align the telescope with the sky and begin finding objects. Once the telescope is powered on, the LCD displa
will guide you through all the steps to align the telescope properly. Before the telescope is ready to be aligned, it should be
set up in an outside location with all accessories (eyepiece, diagonal and Star Pointer) attached and lens cover removed as
described in the
Assembly
section of the manual. Here is an overview of the alignment procedure
1.
Once the NexStar is powered on , Press ENTE to begin alignment.
2.
Use the Up and Down scroll keys to select
,
and press ENTER.
3.
The NexStar display will ask you to move the telescope tube until it is horizontal to the ground. To do this, use the
direction keys (3) to move the telescope until it is roughly level with the ground. Press ENTER.
