Startup Procedure - Celestron CGEM 1100 Instruction Manual

the telescope will automatically slew to. One Star Align uses the same time/location information but only uses one star for
alignment. Solar System Align will display a list of visible daytime objects (planets and the moon) available to align the
telescope. Quick-Align will ask you to input all the same information as you would for the Auto Align procedure. However,
instead of slewing to the alignment stars for centering and alignment, the telescope bypasses this step and simply models the
sky based on the information given. Finally, Last Alignment restores your last saved star alignment and switch position.
Last Alignment also serves as a good safeguard in case the telescope should lose power.

Before any of the described alignments are performed, the telescope mount needs to be positioned so that the index marks are
aligned on both the right ascension and declination axes. (see Fig 3-2).
Once the index position has been set, the hand control
will display the last entered date and time information
stored in the hand control.
1. Press ENTER to begin the alignment process.
2. The hand control will ask the user to set the
mount to its index position. Move the telescope
mount, either manually or with the hand control,
so that the index marked in both R.A. and Dec
are aligned (see Fig
continue.

The hand control will then display the
last entered local time, time zone and
date.

Use the Up/Down keys (10) to view the
current parameters.

Press ENTER to accept the current parameters.

Press UNDO to enter current date, time and location information into the hand control. The following
information will be displayed:
Location - The hand control will display a list of cities to choose from. Choose the city from the database that is
closest to your current observing site. The city you choose will be remembered in the hand controls memory so that
it will be automatically displayed the next time an alignment is done. Alternatively, if you know the exact longitude
and latitude of your observing site, it can be entered directly into the hand control and remembered for future use as
well. To choose a location city:

Use the Up and Down scroll keys to choose between City Database and Custom Site. City Database will
allow you to select the closest city to your observing site from a list of either international or U.S. location.
Custom Site allows you to enter the exact longitude and latitude of your observing site. Select City Database and
press ENTER.

The hand control will allow you to choose from either U.S. or international locations. For a listing of U.S.
locations by state and then by city, press ENTER while United States is displayed. For international
locations, use the Up or Down scroll key to select International and press ENTER.

Use the Up and Down Scroll buttons to choose your current state (or country if International locations was
selected) from the alphabetical listing and press ENTER.

Use the Up and Down Scroll buttons to choose the closest city to your location from the displayed list and
press ENTER.
Time - Enter the current local time for your area. You can enter either the local time (i.e. 08:00), or you can enter
military time (i.e. 20:00 ).

Select PM or AM. If military time was entered, the hand control will bypass this step.

Choose between Standard time or Daylight Savings time. Use the Up and Down scroll buttons (10) to toggle
between options.
