Lessons

  1. The Care and Feeding of an Astronomical Telescope is the single most important aspect of owning an astronomical telescope. If you don't take care of your telescope, what you see through your telescope will look distorted and fuzzy. And if you don't feed your telescope, you might as well turn it into a very expensive lamp, or a kitty condo, if you own a Newtonian.
  2. A Beginner's Guide to Tripod Astrophotography
  3. The Day After Tomorrow: Could it really happen?
  4. Full Moon Names: Harvest, Hunter, Wolf and ... Sturgeon?
  5. Why does the Night Sky Change? How and Why the Night Sky Changes with the Seasons
  6. Your graphical guide to superstring theory: What are superstrings, and how do they relate to our everyday world?
