6. Use the UP and Down scroll keys to select the alignment star

to be replaced, and press ENTER. It is usually best to replace

the star closest to the new object. This will space out your

alignment stars across the sky. If you have used one of the

single object alignment methods then it is always best to

replace the object that is “unassigned” with an actual object.

7. Press ALIGN to make the change.

Selecting an Object

Now that the telescope is properly aligned, you can choose

an object from any of the catalogs in the LCM’s database. The

hand control has a key designated for each of the catalogs in

its database. There are two ways to select objects from the

database;scrollingthroughthenamedobjectlistsandentering

object numbers:

• PressingtheLISTkeyonthehandcontrolwillaccessall

objects in the database that have common names or types.

Each list is broken down into the following categories:

Named Stars, Named Object, Double Stars, Variable Stars

and Asterisms. Selecting any one of these options will

display an alpha-numeric listing of the objects under that

list.PressingtheUpandDownkeys(10)allowsyoutoscroll

through the catalog to the desired object.

• Pressinganyofthecatalogkeys(M,CALD,NGC,orSTAR)

will display a blinking cursor below the name of the catalog

chosen. Use the numeric key pad to enter the number of any

object within these standardized catalogs. For example, to

ﬁnd the Orion Nebula, press the “M” key and enter “042.”

• PressingthePLANETbuttonwillallowyoutousetheUP

and DOWN arrow keys to scroll through and select the eight

planets as well as the Moon.

When scrolling through a long list of objects, holding down

either the Up or Down key will allow you to scroll through the

catalog at a rapid speed.

When entering the number for an SAO star, you are only

required to enter the ﬁrst four digits of the object’s six digit

SAO number. Once the ﬁrst four digits are entered, the hand

control will automatically list all the available SAO objects

beginning with those numbers. This allows you to scroll through

only the SAO stars in the database. For example, in searching

fortheSAOstar40186(Capella),therstfourdigitswouldbe

“0401”. Entering this number will display the closest match

from the SAO stars available in the database. From there you

can scroll down the list and select the desired object.

Slewing to an Object

Once the desired object is displayed on the hand control

screen, you have two options:

• Press the INFO Key. This will give you useful information

about the selected object such as magnitude, constellation

and fascinating facts about many of the objects.

• Press the ENTER Key. This will automatically slew the

telescope to the coordinates of the object. While the

telescope is slewing to the object, the user can still access

manyofthehandcontrolfunctions(suchasdisplaying

informationabouttheobject).

If you slew to an object that is below the horizon, LCM will

notify you by displaying a message reminding you that

you have selected an object outside of your slew limits

(see Slew Limits in the Scope Setup section of the manual).

Press UNDO to go back and select a new object. Press

ENTER to ignore the message and continue the slew. The

LCM hand control will only display objects that are below

the horizon if the Filter Limits are set below 0º in altitude.

See Filter Limits in the Utility Feature section of the manual

for more information on setting the ﬁlter limits.

Caution: Never slew the telescope when someone is looking

into the eyepiece. The telescope can move at fast

slew speeds and may hit an observer in the eye.

Object information can be obtained without having to do a

star alignment. After the telescope is powered on, pressing

any of the catalog keys allows you to scroll through object lists

or enter catalog numbers and view the information about the

object as described above.

Finding Planets

TheLCMcanlocateall8ofoursolarsystemsplanets(including

Pluto)plustheSunandMoon.However,thehandcontrolwill

only display the solar system objects that are above the horizon

(orwithinitslterlimits).Tolocatetheplanets,pressthe

PLANET key on the hand control. The hand control will display

all solar system objects that are above the horizon:

• UsetheUPandDOWNkeystoselecttheplanetthatyou

• PressINFOtoaccessinformationonthedisplayedplanet.

• PressENTERtoslewtothedisplayedplanet.

To allow the Sun to be displayed as an option in the database,

see Sun Menu in the Utilities section of the manual.

Tour Mode

The LCM includes 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. To activate the Tour mode, press the TOUR key on the

hand control. The LCM will display the best objects to observe

that are currently in the sky.

• Toseeinformationanddataaboutthedisplayedobject,

Constellation Tour

In addition to the Tour Mode, the LCM telescope has a

Constellation Tour that allows the user to take a tour of all

the best objects within a particular constellation. Selecting

Constellation from the LIST menu will display all the

constellation names that are above the user deﬁned horizon

(lter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.
