Astronomy without Telescopes

Since the larger towns tend to be north and west of here, our best view is to the south....We have binoculars, but no telescope.


AstronomyCast has a podcast on how to view the stars without a telescope.
Having a Planisphere helps: Uncle Al's Skywheel has PDF files to make your own, and yes, he includes Spanish and Southern Hemisphere charts on his site.
