This OER explores the operation of a Telescope. It combines a lesson on lenses with a lesson using a Galileoscope. It also includes resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.

This text includes 25 reading assignments for an introductory astronomy course. They have been modified from the OpenStax Astronomy 2e and College Physics 2e (linked in related resources below) textbooks to order the topics in a logical manner for a one semester course and provide shortened (~10-20 pages) readings intended for biweekly reading assignments. The text also features enhanced treatment of the Newton's Laws, Energy, and Optics content that go beyond the typical introductory astronomy course for non-majors.
Course connections: This content was built for an introductory survey of astronomy course (e.g., PHYS 103), including apparent motions of objects in the sky, light, telescopes, solar system objects, exoplanets, the sun, stars, galaxies, and cosmology. Basic math skills (arithmetic, powers, scientific notation, unit conversions) will be used frequently. This course is designed for students in all majors.
6.161 offers an introduction to laboratory optics, optical principles, and optical devices and systems. This course covers a wide range of topics, including: polarization properties of light, reflection and refraction, coherence and interference, Fraunhofer and Fresnel diffraction, holography, imaging and transforming properties of lenses, spatial filtering, two-lens coherent optical processor, optical properties of materials, lasers, electro-optic, acousto-optic and liquid-crystal light modulators, optical detectors, optical waveguides and fiber-optic communication systems. Students engage in extensive oral and written communication exercises. There are 12 engineering design points associated with this subject.
