Initialization is a pro- cedure that ensures that AutoStar oper- ates correctly. When you first use AutoStar, it doesn't yet know where the observa- tion location site is, what your model number is (AutoStar operates with several different models of Meade telescopes) or if you are in a daylight savings time period.

During the procedure, you are requested to enter this information. AutoStar uses this information, plus time and date information it receives for a high- precision internal clock to precisely cal- culate the location of celestial objects, such as stars and planets, and how to move your telescope correctly for various operations.

You will only be asked for the location and model number information the first time you initialize AutoStar or after a reset. You can change this information (for example, you may move more than 50 miles away) by going to the Site and Telescope model options in the Setup menu.

7.Set Your Location or Zip Code: The Location screen displays. This screen asks you if you wish to choose either the zip code of your observing location or the location (i.e., entering the city and state or country of your observing location). Press Up to select the zip code option or down to enter the city and state.

Note: The location settings (country/state/province and city, or zip code) are only asked for the first time you turn on the control panel. If you wish to change this set- ting later on, use the Site menu. See SITE, page 27, for more information.

a.If you chose the zip code option, the leftmost “0” is highlighted. Use the Scroll keys to scroll through the digits. When you reach the desired number, use the Right Arrow key to move to the next digit position. Repeat this process until all 5 digits of your zip code are entered. Press ENTER.

b.If you chose the location option, the next screen asks for the country or state/province (list- ed alphabetically) of the observing site.

Use the Scroll keys to scroll through the list of countries, states, and provinces. Press ENTER when the correct location displays.

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.

8.Select model number. As AutoStar operates with several different models of telescopes, it next requests your telescope model number. Use the Scroll keys to cycle through the models. Press ENTER when your model number displays.

9.System initialization is complete. The Easy Alignment feature begins automatically after the control panel is initialized.

TIPS FOR BEGINNERS

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” his or her tele- scope by using high magnifications which the tele- scope’s aperture and atmospheric conditions can not reasonably support. Keep in mind that a small- er, but bright and well-resolved image is far superi- or to one that is larger, but dim and poorly resolved (see below). Powers above 110X should be employed only under the steadiest atmospheric conditions.

AutoStar can calculate the best eyepiece for you to use. Try out the “Eyepiece Calc” feature in the Utilities menu.

Most observers should have three or four additional eyepieces to achieve the full range of reasonable magnifications possible with the ETX telescopes. See OPTIONAL ACCESSORIES, page 32.
