improved. To improve pointing accuracy in another region of

the sky, perform the PAE function again, this time choosing a

bright star in the new region of interest.

Note: If the mount is “parked” before it is powered off (see “Utility

Functions”), the star alignments and PAE corrections will remain

stored in the hand controller. As long as the mount is not moved

between usage, the alignment will not need to be performed

again when the mount is subsequently powered on.

Object Catalog

The GoTo hand controller boasts a vast database of over

13,400 object coordinates and information. The database

contains the following catalogs:

Named Star - A list of 212 well-known bright stars.

Solar System - The other 8 planets of our solar system, and

the Moon.

NGC - 7,840 of the brightest deep sky objects from the NGC

2000.0 database (edited by Roger W. Sinnott, copyright by

Sky Publishing Corp., used with permission).

IC - 5,386 objects from the Index Catalog.

Messier - Complete list of all 110 Messier objects. These are

some of the most spectacular objects to view in the night sky.

Caldwell - Complete list of all 109 Caldwell objects.

Double Stars - Includes 55 of the best double stars to view.

Variable Stars - Includes 20 of the most well-known variable

stars.

User Defined - Up to 25 objects can be saved in the User

Defined database (see “Using the User Defined Database”).

Selecting an Object

Once the telescope has been aligned, you can access and

view the variety of different objects in the GoTo hand control-

ler’s database. There are three methods of selecting a celes-

tial object to view.

1. Shortcut Buttons

TOUR: Takes you on a preset tour across the night sky.

The brightest and most beautiful deep-sky objects will auto-

matically be chosen by the hand controller for your viewing

pleasure. Use the scroll buttons to view the different deep-

sky objects that are available for viewing through the tour

function. Choose the desired object by pressing ENTER. The

LCD screen will display the coordinates of the chosen object.

Press ENTER again, and the hand controller will ask “View

Object?” Press ENTER once more to have the telescope slew

to the object.

M, NGC, IC: These shortcut buttons give you direct access to

the most popular celestial catalogs. Use the numeric buttons

to select an object by entering its catalog number. Pressing

ENTER will display its coordinate. Primary information such

as size, magnitude, and constellation are obtained by press-

ing the scroll buttons. Press ENTER again, and the hand

controller will ask “View Object?” Press ENTER once more to

have the telescope slew to the object.

PLANET: This shortcut button takes you straight to the Planets

submenu in the hand controller’s database. Use the scroll but-

tons to scroll through the list of planets (and the Moon) in

our solar system. Press ENTER to display the chosen planet’s

coordinates. Press ENTER again, and the hand controller will

ask “View Object?” Press ENTER once more to have the tele-

scope slew to the object. If the planet you selected is currently

below the horizon, the hand controller will prompt you to make

another choice.

USER: This shortcut button will take you to the database that

you have defined for yourself. You can enter a new location or

recall the objects that have been previously saved (see “Using

the User Defined Database”).

2. Object Button

The OBJECT button takes you to the Objects Catalog, where

you have complete access to all of the celestial objects in the

database. Simply scroll through the object catalogs using the

scroll buttons and choose the catalog of objects you wish to

view. Press ENTER to confirm your choice. Use the scroll

buttons to choose an individual object within the catalog and

press ENTER a second time to display the object’s coordi-

nate. Press ENTER again, and the hand controller will ask

“View Object?” Press ENTER once more to have the tele-

scope slew to the object.

3. Menu

You can also access the Objects Catalog through the Main

Menu. In the Main Menu, scroll down to “Object Catalog”

and press ENTER. Like the OBJECT button, this gives you

complete access to the 13,400 celestial objects in the hand

controller’s database.

Other Functions

The GoTo hand controller is equipped with a variety of addi-

tional functions that allow you to optimize performance and

access other features of the system.

Utility Functions

Utility Functions are useful tools that provide simple, yet

handy, processes to enhance your observing experience.

Show Position: Displays the coordinates (right ascension

and declination) of the location where the telescope is cur-

rently pointing.

Display Time: Displays the local time and local sidereal time.

Park Scope: Moves the telescope to the “home” position. This

allows you to power off the Sirius EQ-G mount while saving

alignment and PEC training data. When subsequently pow-

ered on, the initial setup information must again be entered

(be sure to enter the current time accurately!), but the align-

ment procedure can be skipped.

Inquire Version: Displays the hardware, firmware, and data-

base version of the GoTo hand controller. If the hand controller

is connected to the mount, this will also display the firmware

version of the motor control board. Use the scroll buttons to

view the version numbers.
