Align requires no knowledge of the night sky it is not necessary to know the name of the stars that you are aiming. You may even select
a planet or the moon. The CPC is then ready to start finding and tracking any of the objects in its 40,000+ object database. Before the
telescope is ready to be aligned, it should be set up in an outside location with all accessories (eyepiece, diagonal and finderscope)
attached and lens cover removed as described in the Assembly section of the manual. To begin Sky Align:
1. Power on the CPC by flipping the switch located on the control panel of
the drive base, to the "on" position. Once turned on the hand control
display will say
CPC Ready
. Press ENTER to choose Sky Align or use
the UP/Down scroll keys (10) to select a different method of alignment.
Pressing the ALIGN key will bypass the other alignment options and the
scrolling text and automatically begins
Sky Align.
2. Once Sky Align has been selected, the hand control will display “Enter if
OK”, “Undo to edit” and “GPS Linking”. The bottom line of the LCD
will display either the current time or the time when you last used the
telescope. The GPS will quickly link up and display the current date,
time and location. Additionally you have the option of pressing UNDO
and manually updating the time/site information. Press ENTER to
accept the time/site information downloaded the GPS.
3. The hand control will display a message reminding you to level the
tripod if you already haven’t done so. Press ENTER to continue.
4. Use the arrow buttons on the hand control to slew (move) the telescope
towards any bright celestial object in the sky. Center the object in the
crosshairs of the finderscope and press ENTER.
5. If the finderscope has been properly aligned with the telescope tube, the
alignment star should now be visible inside the field of view of the
eyepiece. The CPC will ask that you center the bright alignment star in
the center of the eyepiece and press the ALIGN button. This will accept
the star as the first alignment position. (There is no need to adjust the
slewing rate of the motors after each alignment step. The CPC
automatically selects the best slewing rate for aligning objects in both
the finderscope and the eyepiece).
6. For the second alignment object, choose a bright star or planet as far as
possible from the first alignment object. Once again use the arrow
button to center the object in the finderscope and press ENTER. Then
once centered in the eyepiece press the ALIGN button.
7. Repeat the process for the third alignment star. When the telescope has
been aligned to the final stars, the display will read "
Match
Confirmed".
Press UNDO to display the names of the three bright
objects you aligned to, or press ENTER to accept these three objects for
alignment. You are now ready to find your first object.
Tips for Using Sky Align
Remember the following alignment guidelines to make using Sky Align
as simple and accurate as possible.
• Be sure to level the tripod before you begin alignment. The time/site information along with a level tripod will help the telescope
better predict the available bright stars and planets that are above the horizon.
• Remember SkyAlign does not care where the optical tube is pointed at the beginning of the alignment. So to make the alignment
process even faster it is acceptable to move the telescope to the first alignment star manually by loosening both clutches.
However the following alignment stars still need to found and centered using the hand control.
• Remember to select alignment stars that are as far apart in the sky as possible. For best results make sure that the third alignment
star does not lie in a straight line between the first two stars. This may result in a failed alignment.
• Don’t worry about confusing planets for stars when selecting alignment objects. SkyAlign works with the four brightest planets
(Venus, Jupiter, Saturn and Mars) as well as the Moon. In addition to the planets, the hand control has over 80 bright alignment
stars to choose from (down to 2.5 magnitude).
A Few Words on GPS:
The CPC uses an on-board GPS to take the
guesswork out of aligning your telescope with the
sky. Once an alignment method is selected, the
CPC automatically initiates the internal GPS
module. However, there are a few things you
should be aware of in order to get full use of its
many capabilities:
GPS alignment will only work when the
telescope is set-up outdoors with an
unobstructed view of the sky. If the CPC
is set-up in a location that has a limited
horizon in any direction it may take
longer for the telescope to find and link
with the needed satellites.
When using the GPS for the first time, it
may take 3-5 minutes for the CPC to
link-up with its satellites. Once the
telescope is successfully linked, leave the
telescope powered on for at least 20
minutes. During this time the CPC will
download the complete almanac of
orbital elements (called the ephemeris)
for the orbiting GPS satellites. Once this
information is received it will be stored
for future alignments.
If your CPC is transported over a long
distance (say from the northern to the
southern hemisphere) it may take as long
as one hour to establish a satellite link
from its new location. Observers wishing
to travel long distances with their
telescope are advised to turn on their
telescope in advance to allow the GPS to
acquire the necessary data.
