Instruction manual

when the correct location displays.
d. The next screen asks for the city (listed
alphabetically) closest to the observing site.
Use the Scroll keys to scroll through the list
of cities. Press ENTER when the correct city
appears on screen.
5. Daylight Savings Time: The next screen
requests the status of Daylight Savings Time.
If Daylight Savings Time is active, press the
1 key. If Daylight Savings Time is not active,
press the 2 key.
Note: Daylight Savings Time may be referred
to by a different name in various areas of
the world.
6. Telescope Model: AutoStar then asks for the
Telescope Model. Using the scroll keys (Pg. 19,
Fig. 5, 7) on the AutoStar locate the model of
your telescope and press enter.
7. Now enter the current date, then
press ENTER.
8. Enter the current time. Select “AM,” “PM,” or
24-hour clock (blank). Then press ENTER.
9. With “Align: Easy” displayed, use the Scroll
Keys to display “Align: Two Star”. Press Enter.
10. Setting the Home Position: “North Method:
1=True 2=Compass” displays. AutoStar is
asking which Home Position method to use
to setup the telescope. See page 9 “The LT
Series Home Position” for more information.
The easiest way to set the telescope in the
home position is using the Magnetic North
method. Follow the steps on page 9 to set the
home position. If using True North, press the “1”
key, or press the “2” key to use Magnetic North.
Press enter when complete.
11. “Select Star” displays. Autostar then displays a
database of stars for the observer to choose
from. Use the Scroll keys to scroll to a star on
the list that you wish to align upon. Select a
star that you can easily locate in the night sky.
Press ENTER.
12. The telescope slews to the star. Use the Arrow
keys to move the telescope until the star is
centered in the eyepiece. Press ENTER.
13. Repeat procedure for the second alignment
star. The telescope is aligned and you are now
ready to use Autostar’s GO TO capabilities for
a night of observing.
Too Much Power?
Can you ever have too much power? If the
type of power you’re referring to is eyepiece
magnifi cation, yes, you can! The most
common mistake of the beginning observer
is to “overpower” a telescope by using high
magnifi cations which the telescope’s aperture
and atmospheric conditions cannot reasonably
support. Keep in mind that a smaller, but bright
and well-resolved image is far superior to one
that is larger, but dim and poorly resolved (see
Figs. 12a and 12b to the left). Powers above 400X
should be employed only under the steadiest
atmospheric conditions.
Most observers should have three or four
additional eyepieces to achieve the full range
of reasonable magnifi cations possible with
the LT Series telescopes. See OPTIONAL
ACCESSORIES, page 16.

magnifi cation and too much magnifi cation.
