To perform a Landmark Survey
This procedure allows you to perform a tour of the objects entered in the “Object: Landmark”
menu option – note that the Landmark Survey will function only if you have previously entered
objects in the Landmark menu.
1.
Navigate to “Utilities: Landmark Survey” menu and press ENTER.
2.
“Landmark Survey: Slewing...” displays. The telescope moves to the first object on the
Survey list and displays the name of the object.
3.
Press MODE to pause the Survey. Press ENTER to restart the survey at the first object of
the survey.
To check on the available amount of memory in AutoStar.
AutoStar has a limited amount of memory. Once you begin to store Landmarks, User Objects
and other bits of information in AutoStar, you will begin to use up memory. This procedure allows
you to check on how much memory is still available.
1.
Navigate to the “Setup: Statistics” menu option and press ENTER.
2.
“Statistics: 37.2K Char. Free” displays. This is the amount of memory that is still available
to the user.
Identify
This procedure allows you to use AutoStar to identify objects you have found in the night sky
using the Arrow keys. If the object is not in AutoStar’s database, AutoStar displays information
about an object in its database that is closest to the one you queried about.
IMPORTANT NOTE:
The telescope must be successfully aligned before the
Identify feature can be used. Once aligned, it cannot be physically moved from that
location. Moving the telescope disrupts the telescopes frame of reference to the
night sky and will prevent it from identifying objects.
In this procedure, you will center an object you wish to have identified by AutoStar in the
telescope eyepiece and use the “Identify” menu to find out information about the object or the
nearest object to it in the AutoStar database.
1.
Center the object you wish to have identified in the telescope’s eyepiece.
2.
Navigate to the “Object: Identify” option and press ENTER.
3.
“Searching...” displays. When AutoStar finishes calculating, the name of the closest object
displays.
4.
Press a Scroll key to display information about this object. AutoStar displays some or all
the following information about the object with each press of a Scroll key:

Advanced Alt/Az Alignment
If you would rather choose your own alignment stars from the Autostar database during the
Alt/Az alignment procedure, Autostar offers two methods described below. Information for
Equatorial (Polar) alignment is discussed in “Appendix A”, page 49.
