The Practical Astronomer Comprising illustrations of light and colours--practical descriptions of all kinds of telescopes--the use of the equatorial-transit--circular, and other astronomical instruments, a particular account of the Earl of Rosse's large telescopes, and other topics connected with astronomy

"The Practical Astronomer" by Thomas Dick is a scientific publication written in the mid-19th century. The work serves as an introductory guide to the principles of light and color, various types of telescopes, and other astronomical instruments, with the intent of making astronomy more accessible to the general reader. Dick aims to inspire interest in celestial observations and provide practical knowledge about the tools necessary for exploring the night sky. The opening of the volume establishes the significance of light as foundational to astronomy, illustrating its role in the visibility of celestial objects and their observation. Dick elucidates the characteristics and behaviors of light, such as its propagation, reflection, and refraction, laying the groundwork for a deeper understanding of optical instruments. He stresses the moral and divine implications of light, touching upon its beauty and consistency in the universe, while setting up the subsequent sections that will cover telescopes and other related instruments. The reader is invited to appreciate not just the technical aspects of astronomy, but also the broader implications for understanding our place within the cosmos.
