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 an educational guide explaining the basics of astronomy. It starts by discussing light and color, which are key to seeing things in space. Then it talks about different kinds of telescopes and other tools used to study the stars. The book explains how these tools work and how they help us learn about the universe. The author wants more people to be interested in astronomy, so he makes it easier to understand how to use telescopes and other instruments for exploring the night sky and appreciating our place in the cosmos.
