Meade ETX-90PE instruction manual Landmarks, Downloading Tours

STAR "name"

Enter STAR followed by the name of the desired star in quotes. For example: STAR "Vega"

LANDMARK az alt "title" "description"

Enter the azimuth (az) for the desired object in the following format: xxxdxxmxxs. For

example: 123d27m00s. Then enter the altitude of the desired object in the following

format: xxdxxmxxs. Then enter the title string and description string in quotes. For example:

LANDMARK 123d27m00s 57d20m20s "Landmark 1" "North corner of apartment building"

PICK ONE / PICK END

These two statements are used to surround a list of items that AutoStar can choose from during a tour. AutoStar begins at the top of the PICK ONE list and displays the first object from the list that is above the horizon and ignores the rest.

This statement is useful for developing tours that can be presented year round. For each object type you wish to use to illustrate in your tour, pick 10 to 12 examples spaced across the range of right ascension. Bracket them by the PICK ONE / PICK END statements. One current example displays for the user. For example:

AUTO SELECT TEXT "Globular Cluster" "Globular clusters are huge balls of stars."

"They contain 50,000 to 100,000 stars and are located on the fringes of our""galaxy."

PICK ONE

AUTO SELECT MESSIER 13

AUTO SELECT MESSIER 15

AUTO SELECT MESSIER 92

AUTO SELECT MESSIER 4

AUTO SELECT MESSIER 68 AUTO SELECT NGC 1234

AUTO SELECT TEXT "None Available" "I'm sorry. There are no bright globular"

"clusters visible at this time."

PICK END

AUTO SLEW ON / AUTO SLEW OFF

With AUTO SLEW ON enabled in the tour, AutoStar automatically slews the telescope to objects first before displaying the text description. This feature is useful when designing tours in which observing certain objects is required. For example, an astron- omy professor may require his students to observe six objects, four of which AutoStar automatically slews to in a tour. The students would have to manually slew to the last two objects. He would then place AUTO SLEW ON before his first required object and AUTO SLEW OFF after the fourth object.

#END

To end a tour, type the command #END on a separate line at the very end of the tour.

Downloading Tours

Once a tour is written and stored as an ASCII file (saved either as a "text only" or "MS DOS text" file), load it into AutoStar using the AutoStar Update Utility on your PC. As tours are downloaded into the handbox, AutoStar examines the programming. If it doesn't understand the terminology used within a tour, it flags questionable areas and displays them in a pop-up window on your computer screen. Make the necessary corrections and try to download again. See the instruction sheet with your #505 Cable Connector Kit for more information about downloading data to and interfacing with AutoStar.

Landmarks

This menu option allows you to define and store terrestrial objects in the Landmark database. First, a landmark needs to be stored in memory using the "Landmark: Add" option. To view a landmark, use the "Landmark: Select" option. Landmarks may also be viewed using the "Landmark Survey" option in the Utilities menu.
