ADVANCED AUTOSTAR II FEATURES
Before trying out the examples in this section, familiarize yourself with the basic oper-
ations of A
utostar II described earlier in this manual. The following examples assume
that you have a basic knowledge of Autostar II and understand how to scroll to a
desired men
u or menu option, and how to enter numbers and text. It also assumes
that you have initialized and aligned your telescope.
Adding Observing Sites
If you plan to observe using Autostar II at different geographic locations, you can store
obser
vation sites in Autostar II's memory to help simplify your telescope setup.
Perform these procedures using the Site options (Add, Select, Delete, Edit) of the
Setup menu.
To Add a Site to the user-defined site list:
In this example, you will choose a city and add it to the database list. You will then
select the site to enable it.
1. Navigate to the "Setup: Site" menu. Press ENTER,
2. Scroll through the options until "Site: Add" displays. Press ENTER.
3. Scroll through the list of countries/states. Press ENTER when the country/state

method.

list of sites. When the desired site displays, press ENTER.
To Edit a Site:
In this procedure, you will enter a location that is not available in the Autostar II data-
base by editing data of a nearby site. You will edit the location's name, latitude, longi-
tude, and the time zone shift. You will then select the site to enable it.
You will need to know the latitude and longitude of your location to perform this pro-
cedure.

site and press ENTER so that the site is added to your observing sites list.
