My 25" dob is equipped with ServoCat and Argo Navis and can track satellites without needing a computer... but the AN *is* a computer, of sorts. From the manual... "Argo Navisâ„¢ has a powerful 32 bit CPU at its heart that will guide you continuously to keep track of satellites. The sophisticated software even accounts for precession and atmospheric refraction." Wonder if anyone ever got knocked off their ladder using a big Dob to track satellites? |

It is folly to even try to track a satellite while on the ladder of a big dob. It is hard enough to track a satellite that is low enough to have both feet on the ground. The eyepiece on my dob is about 8 feet from the azimuth pivot, so it moves pretty quickly! |

Every goto mount controller, every hand controller that is anything more than four buttons, has a computer in it. As does the system controlling his dob. He just means that he doesn't require an _external_ computer to manage satellite tracking. |

A computer without a computer... :-) And finding something which really is without a computer is getting increasingly hard... |

Every time it plugged in, time/date has to be entered or location if changed. Far as I know, if used for tracking from external software and PC , it tracks in leapfrog mode, not continuous. Interesting article about how to convert it for continuous tracking, using ardunio! https://sites.google.com/site/wayneh...-mount-control |
