You can love telescopes in Centennial.

What it really is

Three things to try today

  1. Look through anything curved and see what it does to light.
  2. Find out the size of the biggest telescope on earth.
  3. Look at the Moon through binoculars.

For the grown-up reading this

Nobody has to talk a child into liking telescopes. They have to not talk them out of it. Centennial is one of the cities the Denver–Aurora–Centennial, CO metro area is officially named after.

Aperture, not magnification, is the number that matters. Say so early.
