Meade LX200 Instruction Manual page 21

You can use the object library in the following ways:
Directly access the library by using the M, STAR, or CNGC
keys (see THE LX200 KEYPAD HANDCONTROLLER, page 14)
and entering a specific catalog number.
Use the START FIND option to find objects in organized
strips of the sky that can be custom tailored to show only the
objects that you wish to see with a selection of object types,
size brightness.
Scan the sky and have the object library tell you what is in
the field of view in the eyepiece by using the FIELD option.
Below is a description of the four OBJECT LIBRARY menu
files and file options:
To access the OBJECT LIBRARY menu file, move the arrow to
the OBJECTLIBRARY display by pressing the PREV or NEXT
key while in the T E L E S C O P E / O B J E C T L I B R A RY m o d e .
Press the E N T E R k e y. You can access the four menu
selections within the OBJECT LIBRARY by moving the arrow
to the desired menu selection with the PREV or NEXT keys
and performing the following steps.
a. OBJECT INFO: Press the ENTER key to read the type,
brightness, size, and quality. Press ENTER again to read
the coordinates. Press ENTER once more to determine
how far off the telescope is pointing from the entered object
(this is displayed in LCD bars: each bar is 10°, or if it is on
the object, no bars). You can access the same information
at any time by pressing the ENTER key for any object
entered by the M, STAR, or CNGC keys. Press MODE to
exit to the main menu file.
b. START FIND: The START FIND option resources the
CNGC objects within the object library and begins a logical
search, starting wherever the telescope is positioned when
activated. To cover the entire visible sky, it will make 31
strip divisions of about 12° width, moving from West to
East, from the North Pole to the South Pole, then South to
North. Once it has found all the CNGC objects, it repeats
its sequence until new objects are visible.
Press the ENTER key and the hand control displays the
first object in its finding sequence. This object is selected
by the LX200, based on where the instrument is pointing in
the sky when you entered START FIND. To point your
LX200 to the object displayed, press the GO TO key; it will
slew to the object.
While in the START FIND option, you can either choose the
next object in line or skip it. To find the next object in
sequence, press the NEXT key; the display will show the
new CNGC object. If you do not wish to view this object,
press NEXT again. If you wish to return to a previously
viewed object, press the PREV key until the desired
catalog number is displayed and press the GO TO key. If
you have set some limitations in the PARAMETERS option,
the telescope will find only those objects within your chosen
confines.
If you find that the object is not well centered in the
eyepiece after you executing a GO TO (due to poor
leveling, improper time input, or errors in site location),
center the object; then press and hold the ENTER key until
the display reads COORDINATES MATCHES. This feature
synchronizes the LX200 for an area of the sky, so that the
next object (if the leveling, time input, or site location
information is not corrected) will be better centered,
provided it is not too far away from the object to which you
matched coordinates.
To exit the START FIND menu selection and return to
the main menu, press MODE.
c. FIELD: Press the ENTER key to identify objects in the
field of view of the telescope. The LX200 displays the
object centered in the eyepiece field, and it shows how
many other NGC objects are in the field at the same
time (defined by the RADIUS parameter setting) as
shown in Display 28:
Objects: 5
Display 28
Center: CNGC 4438
Press the ENTER key to see information about the
object as shown in Display 29:
CNGC 4438 VG GAL
Display 29
MAG 10.1 SZ 9.3'
Read Display 29 as follows:
COMPUTERIZED NEW GENERAL CATALOG Object
#4438, VERY GOOD, GALAXY, MAGNITUDE 10.1,
SIZE 9.3' (in arc minutes).
Press ENTER again to read the coordinate location of
the object as shown in Display 30 (the * after the R.A.
coordinate number indicates the catalog coordinates
of the object, not necessarily where the telescope is
pointing) :
RA = 12:27.2*
Display 30
DEC = +13'03
Press E N T E R once more to see how far your
telescope will have to move to acquire the object
entered. The display shows LED bars, with each bar
representing 10° of movement, as shown in Display
31:

If you are centered on the object already (if you are in
the FIELD menu selection or if you have made a GO
TO command in one of the other methods for finding
an object), the above display will be blank.To review
any of the data on an object, continue pressing
ENTER until the desired field appears.
You can use these commands in any of the following
situations:
When you have an object entered in the keypad
While directly entering specific objects by pressing
the M, STAR, or CNGC keys
In the START FIND menu selection
In the OBJECT INFORMATION menu selection
In the FIELD menu selection
