In this insightful work on astronomy, the writer attempts to explain how much of the fundamentals of Astronomy can be obtained with the coarsest observation with the naked eye, and that the instrumental images derived from a standard globe are sufficient for understanding the instruments in an Observatory. His main aim is to impress upon the student of Astronomy that nothing is entirely beyond his reach.

This is a concise work on several elements concerning the subject of astronomy. It's a perfect book for beginners in astronomy that introduces them to telescopes, planets, stars, skies, and celestial maps. The American astronomer and the author of this work, Harold Jacoby, described the topics in simple and easy-to-understand language. Jacoby made many observations of celestial occurrences such as lunar and solar eclipses. He was popular in Europe and America and was a member of many scientific groups. Contents include: Navigation at Sea The Pleiades The Pole-Star Nebulæ Temporary Stars Galileo The Planet of 1898 How to Make a Sun-Dial Photography in Astronomy Time Standards of the World Motions of the Earth's Pole Saturn's Rings The Heliometer Occultations Mounting Great Telescopes The Astronomer's Pole The Moon Hoax The Sun's Destination

Excerpt from Practical Talks by an Astronomer The present volume has not been designed as a systematic treatise on astronomy. There are many excellent books of that kind, suitable for serious students as well as the general reader; but they are necessarily somewhat dry and unattractive, because they must aim at completeness. Completeness means detail, and detail means dryness. But the science of astronomy contains subjects that admit of detached treatment; and as many of these are precisely the ones of greatest general interest, it has seemed well to select several, and describe them in language free from technicalities.
