Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the
Sun. Do not look through the telescope as it is moving.
APPENDIX B: THE MOON
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 specific 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 astro-
nauts (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.
