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 field of view of your eyepiece. Addi-
tionally, Identify Mode can be used to find 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
defined 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 different speed rates.
1 = 2x
2 = 4x
3 = 8x
4 = 16x
5 = 32x
Nine available slew speeds

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.
6 = .3º / sec
7 = 1º / sec
8 = 2º / sec
9 = 3.5º / sec
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 field 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 definition 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 defined 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.
