coordinates of the object. Press it again to display the text

- To slew to the object displayed, press ENTER.

- To see the next tour object, press the DOWN key.

Identify Button

Pressing the IDENTIFY button will search SkyProdigy’s database

catalogs and display the name and angular distances to the near-

est matching objects from the telescope’s current location. This

feature can serve two purposes. First, it can be used to identify

an unknown object in the eld of view of your eyepiece. Addi-

tionally, Identify Mode can be used to nd other celestial objects

that are close to the objects you are currently observing.

For example, if your telescope is pointed at the brightest star in

the constellation Lyra, choosing Identify will no doubt return the

star Vega as the star you are observing. However, the Identify

feature will also search its NGC and Solar System databases and

display any planets or Deep Sky objects that are close by. In this

example, the Ring Nebula (M57) would display as being

approximately 6° away.

The brightness and proximity of the objects displayed can be

dened by the user using the Identify Filter under Telescope

Setup.

Direction Buttons

The SkyProdigy has four direction buttons in the center of the

hand control which control the telescope motion in altitude (up

and down) and azimuth (left and right). The telescope can be

controlled at nine dierent speed rates.

1 = 2x 6 = .3º / sec

2 = 4x 7 = 1º / sec

3 = 8x 8 = 2º / sec

4 = 16x 9 = 3.5º / sec

5 = 32x

Motor Speed Button

Pressing the MOTOR SPEED button (12) allows you to instantly

change the speed rate of the motors from high speed slew

rate to precise guiding rate or anywhere in between. Each rate

corresponds to a number on the hand controller key pad. The

number 9 is the fastest rate (approximately 3.5º per second,

depending on power source) and is used for slewing between

objects and locating alignment stars. The number 1 on the hand

control is the slowest rate (2x sidereal) and can be used for

accurate centering of objects in the eyepiece. To change the

speed rate of the motors:

• Press the MOTOR SPEED key on the hand control. The LCD

will display the current speed rate.

• Press the number on the hand control that corresponds to

the desired speed.

The hand control has a “double button” feature that allows you

to instantly speed up the motors without having to choose a

speed rate. To use this feature, simply press the arrow button

that corresponds to the direction that you want to move the

telescope. While holding that button down, press the opposite

directional button. This will increase the speed to the maximum

slew rate.

When using the UP and DOWN buttons on the hand control, the

slower slew rates (6 and lower) move the motors in the opposite

direction than the faster slew rates (7- 9). This is done so that an

object will move in the appropriate direction when looking into

the eyepiece (i.e. pressing the up arrow button will move the star

upwards in the eld of view of the eyepiece). However, if any of

the slower slew rates (rate 6 and below) are used to center an

object in the StarPointer, you may need to press the opposite

directional button to make the telescope move in the correct

direction.

Help Button

The HELP button gives you instant access to helpful information

and useful utilities that can help improve the pointing accuracy

of your telescope.

• General FAQ – Is a quick reference to many of the features

and function of your telescope.

• Glossary – Provides denition to many astronomical terms

you may come across while using your telescope.

• The HELP button can also be used to diagnose and improve

pointing accuracy should you notice that bright objects are

not well centered (or completely missing) in the eyepiece.

This is particularly useful when using the StarSense Manual

alignment process in which only a small portion of the sky is

used to align the telescope. To use the HELP button to improve

accuracy:

1. Slew to the database object that is not visible (or not well

centered) in the eyepiece.

2. After the slew is complete press the HELP button. Do not

attempt to use the direction buttons to manually search for

the object.

3. The telescope will then slew to a nearby bright star and

take a reference image. SkyProdigy will make adjustments

to its sky alignment model based on the stars captured

in the image. Once complete, slew the telescope back to

the original object. You should notice a considerable

improvement in pointing accuracy in that region of the sky.

Menu Button

SkyProdigy contains many user dened setup functions

designed to give the user control over the telescope’s many

features. All of the set up and utility features can be accessed by

pressing the MENU key and scrolling through the options below.

In order to make navigating through the hand control menus

as easy as possible, the menu levels are divided into Basic and

Advanced functions.
