Astronomy Fundamentals : Core Concepts About Telescopes

No piece of equipment is more central to our stargazing hobby than the telescope. Many telescope users have discovered that they get a lot more satisfaction out of their 'scopes if, instead of thinking of their telescope as a magical device that somehow shows them the heavens, they gain a basic understanding of how the telescope does what it does.

For the December 16th Astronomy Fundamentals program, long-time member and telescope user & designer Drew Carhart will provide a genuinely fundamental overview of telescope basics. Have you had trouble conceptualizing why f-number is sometimes more important than objective diameter? What the mm number on an eyepiece means? What the heck an exit pupil actually is? Or how different -- or similar -- a refractor is from a catadioptric telescope? Drew will touch on these concepts and more.
