A question: The NexStar computerized hand controller is/was advertised as containing a database of 40,000 objects, and one of the catalogs it lists is SAO (Smithsonian Astrophysical Observatory). The SAO catalog contains over 258,000 objects. Can anyone tell me what are the limiting criteria of the SAO objects available through Celestron's database?
NexStar 8i SCT, Orion 80ED APO refractor, Orion 120 mm EQ refractor, 3.5-inch Questar
