Celestron hand controls have a Star button that directly accesses SAO (Smithsonian Astrophysical Observatory catalog) stars in the scope’s firmware database. You can also find these stars by pressing List, then scrolling to SAO.
The display will show “SAO left digits” and “0000XX.” Since the hand control doesn't have all quarter-million SAO stars, the leftmost 4 digits will be prompted and then you scroll down to the SAO number you actually want. As one example, Arcturus is also known as SAO 100944. Enter 1009 and scroll through 100922, 100925, 100929 etc. until you reach 100944. The gaps in the sequence represent the stars not in the hand control but in the SAO catalog.
If the star has only 5 or fewer digits, put in leading zeros to make up the four digits. For example, to find 37693, enter 0376 and then scroll to find 37693.
Here is the location for named star, variable star, and SAO star lists for Celestron scopes. The lists are provided in PDF and XLS formats: http://downloads.celestron.com/index.php?subdir=Archives%2FMiscellaneous%2FStar-Lists&sortby=name
Check with the Smithsonian Astrophysical Observatory for the complete SAO catalog of 258,996 objects: http://tdc-www.harvard.edu/catalogs/sao.html
Note: Don’t confuse the order number on the SAO list with the actual SAO number or you will end up looking at a different star in another part of the sky.
