Press the “ OBJECT ” shortcut key. The screen will display “ OBJECT LIST ” in the top row. Use
the two scroll keys to browse the list until “ Caldwell Catalog ” is displayed, and then press
the ENTER key. The screen will then display “ Caldwell Catalog / Cald. #= ” for a 3-digit Cald-
well index number between 1 and 109 to be entered in.
2. View Information on the Object:
• The operation is similar to that of locating Messier objects; refer to Section 5.1 for de-
tails.

ENTER key. The screen will then display “ SAO Catalog / SAO 0000xx ” to wait for input of the
4 left-most digits of the 6 digits SAO index number (i.e. “ SAO 0238xx ”). Press ENTER key
and then the hand control will find the first SAO number in the database that matches the
4 left-most digits entered (i.e. “ SAO 023801 ”)
Use the scroll keys to change the last 2 digits until the screen displays the desired SAO
index number. Press the ENTER key to confirm the input. (i.e. “ SAO 023825 ”)
Note: The SAO catalog in the SynScan hand control is a sub-set of the SAO catalog. It
only contains stars brighter than magnitude 8.
• The operation is similar to that of locating Messier objects; refer to Section 5.1 for de-
tails.
• The operation is similar to that of locating Messier objects; refer to Section 5.1 for de-

tails.
• For named stars, Distance to Earth in light years( DIST.), Spectral type, Bayer Desig-
nated name, catalog(SAO, HIP, HD) number are provided.
• For double stars, the separation angle ( Separation: ) and the position angle ( Position
Angle ) are provided.
• For varialble stars, the separation angle ( Separation: ) and the position angle ( Position
Angle ) are provided.
