TwoStarAlign uses the entered time/location information and
allows the user to select which two alignment stars 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.
Startup proCEDurE
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 3-2). Press Enter to continue.

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
