APPENDIX I:

THE MOON MENU

The Moon option of the Object menu allows you to observe the

moon in a way never possible before. You will be able locate

many specifi c features of the lunar surface, including hundreds

of craters, mare, valleys, and mountains. One special feature

allows you to view all six Apollo landing sites. While you won’t

be able to see details such as any of the lunar landers or lunar

excursion modules left behind by the astronauts (the best earth-

based telescopes can only resolve features of about a half-mile

across), you’ll be able pinpoint the landing sites and study the

terrain surrounding these sites.

When AutoStar II syncs to a lunar feature, the telescope switches

to Selenographic coordinates, i.e., lunar latitude and longitude.

To observe the Apollo 15 landing site using the
Moon option:

1. Initialize and align the telescope system as

previously described.

2. Press “5” on the AutoStar II keypad. “Solar

System: Mercury” displays.

Lakes, and Valleys and Rills.

6. Select a distinct lunar crater with which you are

familiar, such as Copernicus or Kepler, from the

Craters option and press ENTER.

7. Then press GO TO to slew to that feature.

Center the feature in the eyepiece and hold

down ENTER for more than two seconds to

ENTER TO SYNC. The telescope is now synced to

Selenographic coordinates.
