NOTE: Starfinder only prompts you to enter Country (or State) and City as described in steps 3, 4, and 5, the first time it is activated. These prompts do not appear again, unless you reset Starfinder (see "RESET," page 32).

However, if you need to enter this information (e.g., you change your geographic location), you need not perform a Reset, which erases user entered data, such as Landmarks and User Objects. You can change the location information by using the Site option of the Setup menu. See "SITE," page 32, for detailed information.

4.Use the Scroll keys (6 and 7, Fig. 13) to cycle through the database of countries, states, and provinces. Press ENTER when the correct location displays.

5.Starfinder then prompts you to enter the nearest city (listed alphabetically) to the observing site. Use the Scroll keys to cycle through the database of cities. Press ENTER when the correct city appears on screen. The display then reads "Align: One Star." You now can use Starfinder's Arrow keys to move the telescope to observe.

NOTE: If you go past the "Align: One Star" (or any other menu display you wish to select), press MODE to return to the previous display(s).

6.Press the Arrow keys (5, Fig. 13) to slew (move) the telescope up, down, right, or left. You can slew (move) the telescope at different speeds.

Slew Speeds

Starfinder has seven slew (move) speeds. Each speed has been calculated to accom- plish specific functions. Pressing the Speed/? key (8, Fig. 13) briefly changes the slew speed, which is shown briefly on Starfinder’s display as the key is pressed. Each press decreases the slew speed down one level and then cycles back to the fastest speed.

NOTE: Pressing the Speed/? key briefly changes the slew speed. Holding down the Speed/? key longer (one to two seconds) accesses the Help function.

The seven available speeds are:

Speed 1	Max	=	240 x sidereal (60 arc-min/sec or 1°/sec)
Speed 2	0.5°	=	120 x sidereal (30 arc-min/sec or 0.5°/sec)
Speed 3	64X	=	64 x sidereal (16 arc-min/sec or 0.27°/sec)
Speed 4	32X	=	32 x sidereal (8 arc-min/sec or 0.13°/sec)
Speed 5	16X	=	16 x sidereal (4 arc-min/sec or 0.067°/sec)
Speed 6	8X	=	8 x sidereal (2 arc-min/sec or 0.033°/sec)
Speed 7	2X	=	2 x sidereal (0.5 arc-min/sec or 0.008°/sec)
