Tour Mode

The telescopes include a tour feature which automatically

allows the user to choose from a list of interesting objects

based on the date and time in which you are observing. The

automatic tour will display only those objects that are within

your set ﬁlter limits (see Filter Limits in the Setup Procedures

section of the manual). To activate the Tour mode, press the

TOUR key (6) on the hand control. The hand control will display

the best objects to observe that are currently in the sky.

Constellation Tour

In addition to the Tour Mode, your telescope has a Constellation

Tour that allows the user to take a tour of all the best objects in

each of the 88 constellations. Selecting Constellation from the

LIST menu will display all the constellation names that are above

the user deﬁned horizon (ﬁlter limits). Once a constellation is

selected, you can choose from any of the database object catalogs

to produce a list of all the available objects in that constellation.

Direction Buttons

The hand control has four direction buttons (3) in the center

of the hand control which control the telescope’s motion

in altitude (up and down) and azimuth (left and right). The

telescope can be controlled at nine different speed rates.

Rate Button

Pressing the RATE key (11) 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 (3º 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 (0.5x

sidereal) and can be used for accurate centering of objects in

the eyepiece and photographic guiding. To change the speed

rate of the motors:

• PresstheRATE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 number will appear in the upper-right

corner of the LCD display to indicate that the rate has

been changed.

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 slew rate to the

maximum slew rate.

The direction that a star moves in the eyepiece when a direction

is pressed will change depending on which side of the Meridian

the telescope tube is positioned. In order to change the

direction of the arrow buttons, see Scope Setup Features later

in this section.

SEtup proCEDurES

The Hand Control contains many user deﬁned setup functions

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

advanced features. All of the setup and utility features can be

accessed by pressing the MENU key and scrolling through

the options:

Tracking Mode — This allows you to change the way the

telescope tracks depending on the type of mount being used

to support the telescope. The telescope has three different

tracking modes:

EQ North Used to track the sky when the telescope is

polar aligned in the Northern Hemisphere.

EQ South Used to track the sky when the telescope is

polar aligned in the Southern Hemisphere.

Off When using the telescope for terrestrial

(land) observation, the tracking can be

turned off so that the telescope

never moves.

Tracking Rate — In addition to being able to move the

telescope with the hand control buttons, your telescope will

continually track a celestial object as it moves across the night

sky. The tracking rate can be changed depending on what

type of object is being observed:

Sidereal This rate compensates for the rotation

of the Earth by moving the telescope at

the same rate as the rotation of the Earth,

but in the opposite direction. When the

telescope is polar aligned, this can be

accomplished by moving the telescope in

right ascension only.

Lunar Used for tracking the moon when

observing the lunar landscape.

Solar Used for tracking the Sun when solar

observing with the proper ﬁlter.

ViewTime-Site— Displays the current time and longitude/

latitude downloaded from the optional CN-16 GPS receiver.

It will also display other relevant time-site information like

time zone, daylight saving and local sidereal time. Local

sidereal time (LST) is useful for knowing the right ascension

of celestial objects that are located on the Meridian at that

time. View Time-Site will always display the last saved time and

location entered while it is linking with the GPS. Once current

information has been received, it will update the displayed

information. If GPS is switched off or not present, the hand

control will only display the last saved time and location.

User Deﬁned Objects — Your telescope can store up to 100

different user deﬁned objects in its memory. The objects can

be daytime land objects or an interesting celestial object that

you discover that is not included in the regular database. There

are several ways to save an object to memory depending on

what type of object it is:

GoTo Object To go to any of the user deﬁned objects

stored in the database, scroll down to
