5.Info: Displays coordinates and useful information about objects selected from the NexStar database.

6.Tour: Activates the tour mode, which seeks out all the best objects for the current date and time, and automatically slews the NexStar to those objects.

7.Enter: Pressing Enter allows you to select any of the NexStar functions and accept entered parameters.

8.Undo: Undo will take you out of the current menu and display the previous level of the menu path. Press Undo repeatedly to get back to a main menu or use it to erase data entered by mistake.

9.Menu: Displays the many setup and utilities functions such as tracking rate and user defined objects and many others.

10.Scroll Keys: Used to scroll up and down within any of the menu lists. A double-arrow will appear on the right side of the LCD when there are sub-menus below the displayed menu. Using these keys will scroll through those sub-menus.

11.Rate: Instantly changes the rate of speed of the motors when the direction buttons are pressed.

12.RS-232 Jack: Allows you to interface with a computer and control the NexStar remotely.

Hand Control Operation

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 sky; 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 slew limits, PEC and backlash compensation.

Alignment Procedures

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 many ways to align the NexStar with the sky depending on what information the user is able to provide: GPS Align Mode allows the NexStar to acquire all the necessary information needed to point itself to the required alignment stars; AutoAlign will ask the user to input date and location information in order to locate the alignment stars; Two-Star Alignment does not require the user to input date and location data, but does require the user to identify and manually slew the telescope to the two alignment stars. Quick-Alignwill ask you to input all the same information as you would for the AutoAlign procedure. However, instead of slewing to two alignment stars for centering and alignment, the telescope bypasses this step and simply models the sky based on the information given. Finally, EQ North and EQ South

Definition alignments are designed to assist you in aligning the NexStar when polar aligned using an equatorial wedge. Each alignment method is discussed in detail below.

"Altazimuth" or "Alt-Az" refers to a type of mounting that allows a telescope to move in both altitude (up and down) and azimuth (left and right) with respect to the ground. This is the simplest form of mounting in which the telescope is attached directly to a tripod without the use of an equatorial wedge.
