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.

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.

LT Series TIPS

Too Much Power?

Can you ever have too much power? If the type of power you’re referring to is eyepiece magnification, yes, you can! The most common mistake of the beginning observer is to “overpower” a telescope by using high magnifications 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 magnifications possible with the LT Series telescopes. See OPTIONAL ACCESSORIES, page 16.

Figs. 12a & 12b: Jupiter; examples of the right amount of magnification and too much magnification.
