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.

Moon option:

familiar, such as Copernicus or Kepler, from the
Craters option and press ENTER.
7. Then press GO TO to slew to that feature.
