APPENDIX E: INITIALIZATION EXAMPLE

Initialization is a procedure that ensures that Autostar operates correctly. When you first use Autostar, it doesn't yet know where the observation location site is or the time or date of the observation session.

During the procedure, information, such as the current time and date, observation location, and telescope model, is entered into Autostar. Autostar uses this information to precisely calculate the location of celestial objects (such as stars and planets) and how to move your telescope correctly for various operations.

The diagram below depicts an example of the Autostar initialization procedure. The following are the parameters that are used in the example:
