COMPUTERIZED TELESCOPE
TIPS FOR USING SKYALIGN
Remember the following alignment guidelines to make using SkyAlign 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 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).
> Rarely SkyAlign will not be able to determine what three alignment objects were centered.
This sometime happens when a bright planet or the Moon passes near one of the brighter stars.
In situations like these it is best to try to avoid aligning to either object if possible.
> Be sure to center the objects with the same final movements as the direction of the Go To
Approach. For example, if the scope normally finishes a Go To with the front of the scope moving
right and up, you should center all three alignment objects in the eyepiece using the right and up
arrow buttons (the up/down arrows reverse at slew rates of 6 or lower). Approaching the star from this
direction when looking through the eyepiece will eliminate much of the backlash between the gears
and assure the most accurate alignment possible.
AUTO TWO-STAR ALIGN
As with
SKYALIGN
, Auto Two-Star Align requires you to enter all the necessary time/site information
as before. Once this information is entered, NexStar will prompt you to select and point the tele-
scope at one known star in the sky. The NexStar now has all the information it needs to automatically
choose a second star that will assure the best possible alignment. Once selected the telescope will
automatically slew to that second alignment star to complete the alignment. With the NexStar set up
outside with all accessories attached and the tripod leveled, follow the steps below to align the tele-
scope:
1. Once the NexStar is powered on, Press
ENTER
to begin alignment.
2. Use the
UP
and
DOWN
scroll keys to select Auto Two-Star Align and press
ENTER
.
3. The Hand Control will display the last time and location information that was entered into
the Hand Control. Use the
UP
and
DOWN
buttons to scroll through the information. Press
ENTER
to accept the current information or press
UNDO
to manually edit the information
(see SkyAlign section for detailed instruction on entering time/site information).
4. The display will now prompt you to select a bright star from the displayed list on the hand
control. Use
UP
and
DOWN
buttons (6 and 9 on the keypad) to scroll to the desired star and
then press
ENTER
.
5. Use the arrow buttons to slew the telescope to the star you selected. Center the star in the
finderscope and press
ENTER
. Finally, center the star in the eyepiece and press
ALIGN
.
