| Coronado 497 Autostar Controller with 30,000 Object Database Including "Sun as an Object". |
- Additional Capabilities: In addition to database object selection and observation, Autostar permits a wide array of fascinating and educational capabilities.
- Automatic GO TO capability to any astronomical object: of known Right Ascension and Declination, plus digital readouts of telescope position, continuously in RA and Dec.
- Precise sidereal-rate tracking: in either altazimuth or equatorial modes. Once an object is located by Autostar, the telescope automatically tracks it and keeps it centered in the telescope's field of view, fully compensating for the Earth's rotation.
- 200 User-Defined Objects: The observer can add the locations of up to 200 objects of his/her choosing, store these objects in Autostar's memory, and call them up at any time.
- 9-Speed Dual-Axis Operation: Use the Autostar pushbuttons to move the telescope on either or both axes, simultaneously, at any of nine drive speeds, from 2x sidereal to 5°/second. Guided Tours: Allows Autostar to choose the best objects for observing on any given night.
