2.4.2.2 Completing Startup

After the system has completed its startup tasks, it will display the UTC Date/Time,

Mount Type, and geographic location. It will then go into Menu Mode and display the

“Align Telescope” menu item.

Since the date and time you enter on the Gemini will be UTC, you need to set your time

zone for correct conversion to your local time. If the display has gone blank, you will

first need to get into Menu Mode by pressing the MENU button. Use the DEC buttons to

scroll through the menu choices until you get to "Setup" and then press the RA+ button.

You are now in the Setup submenu. Use the DEC buttons to scroll through the menu

choices until you come to “Geogr. Location” and press the RA+ button to select it.

Such navigation sequences will be abbreviated in this manual by using the names of the

submenu items separated by a right arrow “→” symbol. Thus, the menu item you just

chose would be depicted “Setup→Geogr. Location.” Finally, use the DEC buttons to

scroll through the menu choices until you come to “Timezone” and press the RA+ button

to select it.

The display will show the current time zone setting as some number of hours ahead of or

behind the time in Greenwich England. For example, the United States west coast is

UTC-8 hours or 8 hours behind Greenwich when daylight savings time is not in effect.

Press the DEC+ or DEC- buttons to scroll through the time zones. When your time zone

is displayed, press the RA+ button to select it.

Having set your location and time zone correctly, you can store them. Up to four different

locations can be stored and reloaded. These locations default to Hollywood CA, Colfax

CA, Berlin Germany and Sydney, NSW Australia, but can be overwritten by your own

settings. Use the “Setup→Geogr. Location→Store Site” command to store the site name,

coordinates and time zone. You can find more information about this command in

chapter 5.

2.4.2.3 Preferences

Finally, there are some preferences that you can set to tailor Gemini to your liking and to

your particular mount. Most of these are optional and can be changed any time. Such

items include:

• Hand Controller Mode (Visual, Photo, All Speeds)

• Moving Speeds (Slew, GoTo, Center, Guide). Changing the Slew and GoTo

speeds may be needed if a motor keeps stalling during a slew. Often slowing

these speeds down helps.

• Brightness of the HC display

Refer to chapter 5 for details about setting these and other options.

IMPORTANT: Changing your geographic location between northern and southern

hemispheres will reverse the tracking direction (and because of this, also the Safety

Limits). Gemini makes even more internal adjustments when you change the Mount
