improve your pointing accuracy, especially on objects in that
part of the sky.
• If you have aligned your telescope using the One-star align
method, you can use re-align to align to an additional object
in the sky. This will improve the pointing accuracy of your
telescope without having to re-enter addition information.
To replace an existing alignment star with a new alignment star:
1. Select the desired star (or object) from the database and slew
to it.
2. Carefully center the object in the eyepiece.
3. Once centered, press the UNDO button until you are at the
main menu.
4. With
LCM Ready
displayed, press the ALIGN key on the
hand control.
5. The display will then ask you which alignment star you want
to replace.
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 (Sao)
Now that the telescope is properly aligned, you can choose an
object from any of the catalogs in the SkyExpedition’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 first 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,
SkyExpedition 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, plus Pluto,
the Sun and Moon. However, the hand control will only display
the solar system objects that are above the horizon (or within
its filter 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 wish
to observe.
• 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 SkyExpedition 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 SkyExpedition will display the best objects to
observe that are currently in the sky.
• To see information and data about the displayed object, press
the INFO key.
• To slew to the object displayed, press ENTER.
• To see the next tour object, press the Down key.
constellation tour
In addition to the Tour Mode, the SkyExpedition 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
(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.
• To see information and data about the displayed object, press
the INFO key.
• To slew to the object displayed, press ENTER.
• To see the next tour object, press the Up key.
